1. Introduction

Dirty Delay is a plug-in for digital audio workstations which provides time delay effects for adding depth and ambience to your recordings. The plug-in includes support for setting the time delay in terms of tempo and note lengths. It also allows you to add filtering, distortion characteristics and feedback to the delay path for cool musical effects.

Features include:

• Independent Delay Path with Variable Time Controls
• Shelf and Cut Filters
  • Character Processing on the Feedback

WARNING!: Dirty Delay functions as a "feedback" delay. There are gain elements within the delay path that allow you to increase signal levels above unity gain. This can lead to signal accumulation at the output, which can lead to clipping and extremely loud sounds coming through your speakers! You must remain aware of the gain elements that could cause these undesired effects and be prepared to act accordingly if you encounter extreme feedback events.

The particular parameters to watch closely are the Filter (particularly when set above the line), Character Gain, Feedback and Crossfeed. Turn these down to tame feedback. Also be aware that when you automate these parameters, playback through the complete automated sequence might provide the desired control over feedback levels for the song. However, stopping playback at particular points in the automated sequence where these parameters are high may lead to feedback. A quick solution is to mute your speakers, pull down the offending parameters, or jump to a silent section and start the transport.

2. System Requirements

• Pro Tools™ (Mac): Pro Tools 10 or higher running on a Macintosh computer. This software supports Native operation ONLY! Due to limitations in memory resource allocation, Dirty Delay is not supported in AAX DSP.
• Pro Tools™ (Windows): Pro Tools 10 or higher running on a Windows computer. This software supports Native operation ONLY! Due to limitations in memory resource allocation, Dirty Delay is not supported in AAX DSP.
• Native (Mac): Any Mac DAW that supports Audio Unit or VST plug-ins.
• Native (Windows): Any Windows DAW that supports VST plug-ins.
  • Mac: Any Intel-based Mac running Mac OS X 10.6.8 or newer
• Windows: Any Windows PC running Windows 7 or newer
• A PACE iLok.com account. You can install your license on your computer or on an iLok key. Please note that one license authorizes the software on any platform.

3. Installation

For both Mac and Windows, there is a single standard installer for the Production Bundle that allows you to decide which plug-ins to install to your computer, depending on what individual plug-in licenses you own and what formats you use.

IMPORTANT: Please make sure you have your license installed and available before you first launch your host after running the installer. Otherwise, you will receive a message on launch that the software is not licensed, asking you to "Buy" or "Quit". There are some hosts that will not rescan for your plug-ins on the next launch after the license is installed, and some hosts do not provide a user menu preference to rescan.

Mac

Please note— The following graphics show installation on a macOS 12 system; the process may be slightly different in other versions of the OS, but the basic concepts are the same. Small details such as file sizes shown may vary with subsequent releases.

- Important note for Pro Tools users

Version 4 of the AAX plugins will install alongside v3, so both will remain available in your system. There are two reasons for this:

1. The v4 plug-ins are currently Native only and do not provide DSP executables for HDX/Carbon DSP chips.
2. At the request of many Pro Tools users, we have made changes to the AAX v4 plug-ins to provide finer and more consistent behavior of EQ parameters when controlled by EuCon control surfaces and Pro Tools automation.

In some specific workflow cases, these changes have the potential to affect automation playback of older sessions, so the safe route would be to keep older automated sessions running on v3, and using v4 for new sessions.

For specifics on these changes, please see the latest release notes within the v4 plug-in UI by clicking on the Metric Halo logo in the upper left corner of the plug-in window.

Existing sessions will recall with the v3 instances for both Native/DSP, and you can continue to add new instances of the v3 plugins (for example, if you want to be able to use DSP versions for tracking).

You can add v4 instances as you wish to take advantage of the new features and new plug-ins.

You can switch v3 instances to v4, and your settings will be preserved.

If you load sessions with v3 instances, but only have v4 installed, Pro Tools will automatically migrate the instances to v4 Native with the parameter settings intact.

- "Select a Destination" lets you install the plugs for all users (if you are logged in as an admin), only your user, or to another volume entirely.

Update Notification (all platforms)

All Metric Halo Production Bundle plug-ins will automatically check for newer version availability (if your computer is connected to the internet).

Abstract logo design featuring stylized letter 'M' with a red circular element (no text or symbols)

Plug-in Update Alert

If a new version is found, the Metric Halo icon in the plug-in header bar will sport a lovely red dot. Click on the dotted icon and check the Update Notification tab for release notes and download instructions.

4. Plug-In Header Bars

All Metric Halo family plug-ins display the MH control bar directly above the processor control UI. This control bar is very helpful for organizing your MH presets, as it allows you to organize and access all your presets across all supported plug-in formats on Mac, Windows and our hardware DSP via MIOConsole3d.

It is especially useful in that, regardless of platform, it provides a straightforward, powerful and consistent processing workflow wherever you might be working.

With the constant evolution of computer capabilities opening the door to new production techniques and music delivery formats, the differences between DAW software workflows have become ever more diverse. Many of the major DAWs provide their own plug-in headers within every plug-in instance window, providing their own feature set catering specifically to their internal workflow.

Conversely, other equally popular DAWs provide no added feature support for plug-ins (such as plug-in parameter Undo/Redo), opting instead to insert plugs as a straight processing block.

The MH family plug-in header bar bridges that gap by offering the most asked for plug-in functions in a simple GUI, making all of our plug-ins functions and their presets available to every user on every platform.

The plug-in header bar has two rows of controls, with the Metric Halo logo icon at the top row left.

The top row handles plug-in operations, including update notification and download, access to MH online resources, GUI preferences, tooltip help, A/B parameter snapshots, snapshot Blend, plug-in Undo/Redo, Compare and soft Bypass.

A B Blend 140% Compare Bypass Factory Default

MH Plug-in header (default setting: eq and dynamics graph display closed)

The lower row (with the 'hamburger' menu icon at the left) is all about preset management.

The menu includes organizational and preset import/export features for sharing saved preset files with the outside world, and restoring presets from early days MIO and MH plug-in versions.

Clicking the MH icon expands the entire plug-in window to the right and opens a multi-function control sidebar with the Preferences tab in focus:

Plug-in control pane tabs

When updates are available for download from Metric Halo, the MH icon will sport a blatant red dot (shown in the header map at the top of this page) and an Update tab is added to the sidebar. These tabs are dynamic by design, and additional tabs may appear as new content becomes available.

To close the sidebar, click the MH icon again, or the "X" at the right edge of the tab bar.

standard plug-in UI Preferences

The Preferences tab provides controls to modify the color scheme of text and graphical elements.

Initially added in response to requests from users with various visual impairments, in practice the ability to match the color of the plug-in to the mixer strip where it resides makes for a nice improvement in workflow.

Shown above are the basic parameter controls used by the majority of Production Bundle plug-ins.

More complex processors, such as ChannelStrip with multiband EQ and dynamics graph grids, will have additional preferences to further customize those UI elements. Processors with simpler graphics will have fewer UI preference controls.

UI parameter changes are live, so you can see changes to the plug-in graphics as you make them. This includes colors, gradients, graphic element show/hide, knob types and bevels.

Clicking color selection swatches opens the standard OS color pickers window with the eyedropper tool for sampling any color visible on your display.

UI Preferences functions are listed on the next page.

Note: The color scheme you set will be saved to the computer and automatically applied to the next instance of that plug-in type of whatever native format, even on another DAW.

You can always revert to the factory default settings by clicking the Reset Prefs to Factory Default button at the bottom of the Preferences pane.

Complete Plug-in Preferences List

The following is a list of all the preferences available across all of the plug-ins. They don't all apply to every plug-in, but you can refer here to find the documentation for the prefs that that are displayed in the actual plug-in.

Current Release Notes

Preferences About Current Release Notes Important Notes • This version of the AAX plugins are currently Native only and do not provide DSP executables for HDX/Carbon DSP chips. As a result, if you upgrade your AAX plugins to v4, you will not able able to use them on the HDX/Carbon DSP chips but they will continue working natively. • The installer for this version will overwrite earlier versions of the plugins, and the versions installed by this installer require the updated v4 license. This version of the plugins is a complete rewrite of the host-side components of the plugins, and is now based on Metric Halo's MHShell plugin technology. This provides a number of significant benefits to owners of the plugins: • All plugins are now built under a unified shell so they all inherit the base functionality of the shell, including: ○ New look, including skin choice and preferences ○ MH Logo Details view ○ Software update tracking ○ Quick Links to product pages, manuals, and tech support ○ Undo/Redo ○ A/B snapshots, and snapshot blend ○ More flexible resizability ○ Common controls in the header bar (Help, Resize, Pane Disclosure) • Unified build architecture, so all plugins on all platforms (MIO, Mac, Win) receive all updates and improvements simultaneously. • Added support for VST3, so now all plugins support AU, AAX, VST2 and VST3 on macOS, and AAX, VST2, and VST3 on Windows.

Plug-in Snapshot Registers: A/B

A B Blend

Plug-in Header: Snapshot Registers: A/B

The A and B buttons control the A and B state registers. The A/B registers are used to store modified parameter snapshots in addition to the original saved preset called up by Compare.

The Blend function can be used to smoothly morph between the parameters set in the A and B registers, and Blend is a mappable parameter so it can be operated with external MIDI control. Details of the A/B Snapshot Blend feature follow on the next page.

For each of the A and B buttons the visual display tells you the state of the register:

• Light Grey means the register is empty
• Dark Grey means it has settings, but is unselected
- Blue means it has settings and is selected

You can perform the following actions:

• Clicking on an empty register takes a snapshot of the current settings and saves them to the register.
• Clicking on an unselected filled register copies the register parameters to the current active plugin settings.
• Clicking on a selected register toggles to the other register; this lets you toggle between the register settings without having to move the mouse
• - clicking on a register snapshots the current settings and saves them to the register, overwriting the prior contents (if any).
• Changing settings when a register is selected will update the settings in the register to reflect the change.

Snapshot Blend

The Blend button allows you to interpolate (or morph) between the parameter snapshots stored in the A and B registers. It becomes active when both A and B have a parameter set stored.

Blend is a MIDI-mappable parameter so it can be operated in realtime with external MIDI control and/or automated in the DAW. This allows you to automate a transition from the A → B register, the B → A register or any setting between the two.

A B Blend 65.60 A B

Plug-in Header: Snapshot Blend

The Blend button's visual display tells you the state of the register:

• Light Grey means it is empty
- Dark Grey means it has settings, but is unselected
- Blue means it has settings and is selected

Click on Blend to popup the blend control. Slide all the way to the left to apply the settings in the A register. Slide all the way to the right to apply the settings in the B register. Intermediate settings for blend will give you intermediate settings for any parameter that is different in register A and B. The blend control does not change the state of Bypass.

Note that the Blend is not a parallel processing mode where two instances of the processor are running the A and B settings and the output is a parallel blend of the two settings. Rather, Blend interpolates the parameter settings of the two registers to one instance of the processor. You can see the parameter controls move between A and B settings as you slide the Blend control.

The A/B and Blend settings are stored and recalled as part of the plug-in state, but are not saved as individual presets in the preset bar.

While you can use the blend with arbitrary A and B settings we find it works best when you craft the settings in the two registers in such a way as they are related to each other. Specifically, if an indexed (stepped) parameter is different between the two settings, the interpolated value will snap to one of the indexes between the two settings, which can be jarring.

It is best if the parameters that you blend are smooth parameters (e.g. gains, frequencies) and make sure the indexed parameters (enables, modes, band types) are set the same for both registers.

The easiest way to do this is to load the same setting into both registers and then tweak the settings of one of the registers.

This works especially well if you make one of the registers be the basic settings with all the gains or thresholds flattened out so that you can smoothly interpolate between a setting and effectively bypassed - we have found that this allows you to zero in a perfect configuration between too much and too little.

Plug-in Undo/Redo

All the plug-ins provide support for undo/redo from the plug-in header bar.

User interface control panel showing a left-right arrow icon with A and B buttons, labeled 'Blend' button

Plug-in Header: Undo/Redo

The left and right curved arrows represent Undo (Left) and Redo (Right). These arrows are grey when there is nothing to Undo or Redo.

The arrows are white when it is possible to Undo (Left) or Redo (Right). Clicking the left arrow when it is white will undo the last action you made in the plug-in. When you undo something that change is placed on the redo stack, and the Redo button will turn white.

Clicking the Redo button (when it is white) will restore the state that the last Undo changed.

If the Redo button is white and you make a change in the plug-in, the Redo button will go grey as the redo buffer will be cleared.

For MH 3d hardware users: A note regarding plug-in Sidechains

In host-based DAWs, the mechanism for routing signals to plug-in sidechain inputs is handled within the DAW itself in a separate routing UI from the plug-in.

In MIOConsole3d, plug-ins which support external sidechain inputs are assigned from within the plug-in UI (as shown below).

A B Blend 140% Compare Bypass Master CompEQ 1 Sidechain In: Unassigned

MIOConsole3d ChannelStrip header

In MIOConsole3d, sidechain inputs may be routed from any input or bus available in the system, except for the Main bus. These routes are naturally going to be different from what would be assigned in a DAW session.

For this reason, external sidechain assignments are the one parameter which can not translate between a host-based DAW preset and the same preset opened within MIOConsole3d.

5. Operation

The Dirty Delay user interface uses several control elements to operate the plugin. These elements are:

Link Control

The Link Controls button at the upper left corner of the Dirty Delay UI toggles stereo linking of the left and right channel parameters.

Link Off (default state) & Link Controls On

When engaged, any changes made to the left channel control knobs will also change the right channel's knobs, maintaining any pre-existing offset. Changing the right channel's knobs directly will change only for the right channel in order to adjust the desired offset with respect to the left channel knobs.

Control Knob

Control Knobs are used to control various parameters.

5.76 Gain

Control Knob

Some control knobs sweep from a minimum to maximum value, from left to right. Others are centered by default and can sweep left or right to subtract or add value respectively, or to set the parameter as a percentage.

You can change the value of each knob in a number of different ways. Click and drag the knob to change the value continuously. Dragging up or to the right will increase the value, while dragging down or to the left will decrease the value.

If you hold the Mac Option key or Window Alt key when you click, the knob will reset to its default value. You may also double-click a knob to reset it.

Click on the number (readout) of the knob, or right-click or control-click on the knob itself to display a text entry field that allows you to type in a number directly (shown above). The pop-up will remain active until you dismiss it by clicking somewhere else or hitting Return, Enter, Tab, Mac Command +., Windows Alt key or ESC keys. Hit Return or Enter to confirm the value and dismiss the pop-up.

Hit the Tab key to confirm the value and display and entry field for the next control. Shift + Tab will display the entry field for the previous control.

Hit the Mac Command + ., Windows Control + . or ESC (Escape) to dismiss the pop-up and cancel the change.

Toggle Button

Toggle Button (Off & On)

Toggle buttons are simple on/off switches. They light up when they are on and are dark when they are off. Toggle the state of the button by clicking on it. The button shown is used to enable Tempo Sync within Dirty Delay.

Tempo Tap

The Tempo Tap Pad allows you to set the delay time in BPM with successive mouse clicks. Tap in quarter-note beats to set the Tempo.

Note Length

Whole Half Quarter Eighth ✓ Sixteenth Thirty Second Sixty Fourth Manual

Note Length Selector and Popup Menu

The Note Length selector (above left) opens the pop-up menu (above right) to select the note value of the delay with respect to the tempo.

Standard musical note values are available, as well as Manual mode. When set to a musical note, the correct delay time is set automatically and the associated delay knob will be grayed out.

When set to Manual, you can set the delay time using the delay knob. Manual Delay is a full manual mode which overrides all Tempo control of the delay, including Sync and Tap.

Radio Button

Triplet & Dotted Note length modifiers

The buttons used to modify the delay note values with triplet or dotted note time are "radio buttons".

Radio buttons are like toggle buttons, except that they simultaneously disable another parameter when enabled. In the case of triplet and dotted note length modifiers, you can select triplet, dotted or neither, but not both.

Delay Filter

This section allows detailed control over the 2-band EQ applied to the delayed signal.

• The horizontal axis provides frequency calibration in Hertz (Hz).
• The vertical axis provides level calibration in decibels (dBr).
• The heavy green line indicates the relative change in level at each frequency that is created by the combined effects of all the active bands in the equalizer.

Each EQ band is represented by a numbered, colored dot in the transfer function.

The band that is currently being edited will be displayed along with the overall response curve. If the associated band is a parametric filter there will also be two smaller colored dots that can be used to control the bandwidth of the filter.

Clicking on a large colored dot and dragging it will allow you to adjust the frequency and gain of the associated band.

Mac Command-click, Windows Control-click or double click the dot to toggle the band enable.

Mac Option-click or Windows Alt-click the dot to adjust the bandwidth (drag right to increase, and left to decrease bandwidth).

Mac Command+Option-click or Windows Control+Alt-click the dot to switch the band filter type. Click and drag the smaller dots associated with a larger dot to adjust the filter bandwidth.

To dismiss the filter curve, click anywhere in the black area of the transfer function. This will deselect the filter point, and the only trace displayed will be the green master curve.

Filter Type

Each filter band has a filter type control that allows you to choose the shape of the filter applied by that band. Each band provides 6 different types of filter shapes:

Peaking/Parametric

Peaking/Parametric – a second order bell-shaped parametric boost/cut filter. Boost/cut has a range of ± 24 dB. When the boost is greater than +15 dB the filter gains a resonant quality. The center frequency of the filter can be any frequency between 20 Hz and 20 kHz. The bandwidth of the filter is continuously variable between 0.1 octaves and 2.5 octaves.

Low Cut

Low Cut - a 12 dB/octave low cut filter with a -3dB point that is continuously adjustable between 20Hz and 20kHz .

High Cut

High Cut - a 12 dB/octave high cut filter with a -3dB point that is continuously adjustable between 20 Hz and 20kHz .

Low Shelf

Low Shelf – a shelving filter that applies boost/cut to low frequencies. Boost/cut is limited to +12 dB/-24dB. The bandwidth controls the dip/peak that is added at the end of the transition band.

High Shelf

High Shelf – a shelving filter that applies boost/cut to high frequencies. Boost/cut is limited to +12 dB/-24dB. The bandwidth controls the dip/peak that is added at the end of the transition band.

Bandpass

Bandpass – a bandpass filter with 6dB per octave skirt on the high and low ends of the pass band. The width of the pass band can be adjusted between 0.1 octaves and 2.5 octaves and the center of the pass band is continuously adjustable between 20 Hz and 20 kHz.

You can select from these types via three different methods. Each time you click on the Filter Type control, the band will switch to the next type in the list (and wrap to the beginning when you hit the end of the list). If you click and hold the mouse button, a pop-up menu listing all of the types will appear after about 1/4 of a second. You can select the type directly from this pop-up menu. If you want to access the menu without having to wait, hold down the Mac ^ (Control) key when you click or right-click (Mac/Win).

Character Model Menu

Character Popup Menu

This pop-up menu selects the Character model applied to the delayed signal. There are 8 models available, which are detailed in the Processing chapter. The pop-up style menus can also be stepped through using the mouse scroll wheel.

Output Level Meter

RMS (PPM decay) Peak Hold (2 sec) Digital Peak clip VU (VU decay) Peak (PPM decay)

Dirty Delay Output Level Meter

For the main output stage of Dirty Delay we have provided meters driven with SpectraFoo™ metering technology. These meters show digital Peak, Peak Hold, RMS level and VU level.

Both the Peak and RMS level are represented with fast PPM ballistics.

The instantaneous Peak level is represented by the floating colored pip. Peak Hold is 2 seconds, indicated as a red floating marker pip.

The RMS level is the solid colored bar which transitions from green at "safe" high-headroom levels to yellow at -18dBFS, then to orange and finally red approaching -6dBFS.

The VU meter is the white floating marker pip showing IEEE standard 300 ms RMS average level.

The output section clip lights activate if there is an over in the output stage or in any of the processing section input stages. It is reset by clicking on the meter.

A Note About Clipping Indicators:

The clip lights do not mean that the plug-in is clipping; it means that the audio level in the DSP is currently over 0 dBFS. If you do not lower the signal level you run a chance of actually clipping the input of another processor or D/A converter.

In this chapter we'll discuss what each processing block does and how the controls work.

The block diagram above illustrates the overall signal path through Dirty Delay for both the mono and stereo versions. The diagram does not indicate the metering blocks.

Now lets examine the various processing blocks indicated in the diagram and elaborate on additional control elements built around them.

Filter

The filter block provides frequency shaping to a copy of the input signal prior to being delayed. The available controls allow you to set the frequency and level of the variable pre-filters of the delay. Using these controls allows you to tailor desired frequencies with up to +6 dB of boost to -24 dB of cut. See the Delay Filter section in the Operation section for detailed information.

Character

The Character block follows the filter, and applies low order harmonics to the signal being delayed. Each Model represents a digital "copy" of an analog device; some models are made from measuring a device with different combinations of settings. The most effective way to utilize Character is to listen to how each model affects your sound rather than relying on the name alone.

• None: No modeling is applied.
• Valve: A tube-based EQ input stage.
• Soft Sat: Tube-based EQ with saturation.
• Transformer 1 Applies the harmonic distortion signature of a transformer-coupled input.
• Transformer 2: A variation of the "Transformer 1" model.
• Tube DI: Mastering quality tube DI.
• Tube EQ: Mastering quality EQ.
• Tube Soft Sat: Mastering quality EQ with saturation.
• Tube Symmetrical Clipper: Mastering quality EQ

While most of the models can be applied to all types of material, particularly after judicious filtering, overuse of the saturation models can lead to undesired effects.

Drive Gain

Character Drive and Gain controls

The Drive control applies ±24 dB of gain to the signal before it goes to the modeling section. This allows you attenuate the signal for a subtle effect, or boost to get a more dramatic effect.

As gain is changed before the modeling stage, the inverse gain is applied after. For example, if you set the Drive control to +6 dB, the gain is boosted 6 dB before the model and cut by 6 dB after. This allows you to "push" the modeling section with no increase in output level. You may also hit the model with less signal by setting the Drive control to a negative value without loss of overall volume.

You may still experience in increase in signal level when using positive Drive gain with some models; you can use the Gain control to correct this.

Tempo Control

This block generates the reference tempo for metrical time delays. Depending on the setting of the controls in the UI, this may generate the tempo from data provided by the host, by the rate of taps on the tap button or directly from the Tempo knob if the tempo is set manually.

With Sync toggled on, the base tempo automatically locks to the tempo set in your host. Toggle Sync off to manually enter the delay in ms on a per channel basis (stereo), or to tap tempo.

Click the tap button successively at the desired rhythm to set the tempo. When Sync is engaged, the Tap button will be disabled.

Delay

The Note Length sets the resolution of the delay time. The values are defined in note duration (Whole, Half, Quarter, etc.) with respect to the tempo grid.

Triplet and Dotted Note Length modifier buttons

Any note value can be modified to repeat in the form of triplets or dotted notes by engaging these buttons.

Offset

The offset block adjusts when you hear the delayed signal relative to the total feedback delay.

The time offset controlled by this block is adjusted with the Offset Knob in the UI. The Offset knob allows you to make fine adjustments to the groove of the delayed audio.

Turning the knob to the left will make the delays arrive earlier, and turning to the right will make the delays arrive later.

The range of the Offset knob is defined by the delay time. You can adjust the offset in each direction by up to half of the delay time.

Feedback Path

The Feedback path takes the output of the delay line and sums with the input.

The Feedback knob sets how much of the delayed signal is fed back into the delay path. Higher settings will generate more repeats, and can eventually cause the output to clip over time as the repeated signals accumulate.

The Feedback phase invert button causes the feedback to be inverted when it is engaged; every time the signal goes around the feedback loop the polarity will be inverted.

Phase Inversion Button - On (at left) & Off (at right)

Dedicated Phase Invert Buttons are available for both the Feedback and Crossfeed controls.

Crossfeed

The crossfeed controls are only available when using Dirty Delay as a stereo plug-in.

The left crossfeed control sets how much of the left channel delay feedback is fed into the right channel as a percentage, and vice versa for the right crossfeed control.

Wet/Dry Control

The Wet/Dry control sets the mix between the delay (wet) and original (dry) signals as a percentage.

Setting this control to 0 (full dry) lets no delayed sound through.

Setting this control to 100 (full wet) lets only delayed sound pass; you would want to use this setting when inserting Dirty Delay on an aux bus. If you are inserting Dirty Delay directly on an input or bus, use this control to balance the original audio and delay.

Output Gain

The Out Gain control allows you to vary the final output level of Dirty Delay by ±24dB .
