Frequently Asked Questions - Tekturon D16 Group

What are the system requirements for Tekturon?

Tekturon requires Windows 7 or newer (2.8 GHz SSE CPU, 8 GB RAM) or macOS 10.13 or newer (Intel 2.8 GHz or Apple M1, 8 GB RAM). 16 GB RAM and multi-core 3.2 GHz are recommended. It runs as a VST2/VST3/AU/AAX plugin in a compatible host.

How do I set the delay time manually?

Use the Time Grid parameter in the Master section. In sync-off mode, adjust from 1 to 500 ms by dragging the digits. Alternatively, use the Tap button to tap in a rhythm; the plug-in averages the intervals to set the delay.

Can I synchronize delays to my DAW tempo?

Yes, enable the Sync toggle. When active, the Time Grid displays note values (1/8, 1/16, 1/32, 1/64) with rhythmic modifiers: Full, Tri (2/3 duration), or Dot (3/2 duration).

How do I adjust feedback for individual delay lines?

Select the Feedb view using the View Selector. Drag the vertical bars for each delay line (1-16). The effective feedback is the global Feedback value limited by the local bar setting.

What filter types are available and how are they applied?

Each delay line has a multimode filter with types: LP (low-pass), BP (band-pass), HP (high-pass), Off (bypass), or MF (follow Master Filter type). Global Cutoff and Resonance set the base, while per-line bars provide relative offsets.

How do I save and manage presets?

Click the Save button in the Preset section. The Preset Browser allows browsing, searching, filtering by groups/tags, marking favorites (global) or pins (per-instance). Right-click for rename, delete, export (drag-and-drop), and import (drag files into browser).

Can I assign MIDI controllers to parameters?

Yes, right-click any parameter and choose MIDI CC > Learn, then move a controller on your MIDI device. Confirm with OK. To clear, use the Clear button. Save/load MIDI CC maps from the cog menu.

What is the Shuffle parameter?

Shuffle adds a swing effect by increasing delay on even-numbered taps and decreasing on odd-numbered taps by the same amount. The strength is controlled from 0 to max.

How does the Mute function work?

Each delay line has a mute button (toggle). The In/Out switch determines whether the mute cuts the signal before (IN) or after (OUT) the delay line. Muted lines are indicated by dimmed bars.

What are the GUI customization options?

From the cog menu, under GUI, you can adjust Size (multiple skin sizes), System Scale (match to screen resolution), and Theme (color variant). Also save a default state so new instances load with your preferred settings.

CPU usage may vary widely depending on the manner in which the product is used. Factors that may contribute to variance in CPU usage include particular patch and its complexity, the global quality setting, project sample rate. In order to form a better understanding of how a plug-in will behave within your current setup, we highly recommend downloading the demo and giving it a try.

Preliminary information

This chapter contains general advice for using the plug-in's interface.

To do a right-click on macOS with single button mice:

Either use your mouse click while holding the CTRL key on your keyboard or use two fingers on your touchpad.

Checking the value of a parameter

Right-click on any parameter to check its value in its context menu:

A parameter's context menu

Note: It's currently not possible to enter a precise value in the input box; it's just to check the value.

Fine-tuning continuous parameters

Tweak a control (knob) while holding the CTRL key (on Windows) or Apple CMD key (on macOS) - this will make the tweaking more precise while moving the mouse pointer up and down.

Double-click to reset a continuous parameter's value

Double-clicking on a parameter restores its value to the initial state, either default (right after loading the plug-in / loading it along a project file) or from the most recently loaded preset.

Overview

Tekturon is a multi-tap delay effect with 16 independent delay lines.

When the plug-in is loaded, its graphic interface appears:

Tekturon's graphic interface

There are two main sections on the interface:

- Configuration and Preset management section:

Configuration and Preset management section

- All the remaining controls are in the Signal processing.

Signal Flow

At the core of Tekturon are 16 delay lines. The time delay between subsequent taps is equal and controlled by a single parameter – the Time Grid. The taps are labeled by numbers 1 to 16. The signal flowing into tap 1 is not delayed relative to the dry signal. Tap number 2 is delayed by the value of the Time Grid and tap number 3 is delayed by twice the value of the Time grid and so on up to tap 16 (which is delayed by 15 times the Time grid value).

Each delay line also has its own independent feedback loop and an effect chain processing the signal output from the loop.

A delay line FX chain consists of:

• Multimode filter with adjustable Cutoff and Resonance
- Stereo Panning
- Stereo Spread

Bi-level control of the effect

The plug-in is controlled hierarchically:

• Globally - From the Master section, where the delay lines are all altered at once

Master section

- Locally - By adjusting each of the delay line parameters individually using the bar graph display situated on the left side of the GUI.

The Bar graph display

The parameters set globally from the Master section are:

- Base value – A reference point for the relative values (offsets) set locally and individually for each delay line. This is the case for:

• Multimode filter Cutoff
• Multimode filter Resonance
• Delay loop Feedback value

- Parent value – A default value, which can be overridden by the local value; specific for the particular delay line. This happens for

- Multimode filter type

Some of the delay line parameters do not have global counterparts in the Master section. They are controlled individually per delay line from the bar graph display. This applies to:

• Stereo Panning
• Stereo Spread

Certain parameters can only be controlled globally (they cannot be adjusted per delay line). These are:

• Shuffle
• Time grid

Unit delay value – the Time grid

The Time grid is a global parameter which controls:

- The delay time between subsequent Taps – their time spread.

- It is also the base value of the delay time for all delay line feedback loops. Effective delay time for a delay line is defined as multiple of the Time grid in a range x1 to x16:

Effective Loop Delay= N*Time Grid

Delay time in an individual delay line

The parameter value is controlled from the Time grid section on GUI:

The Time grid parameter

It is expressed in milliseconds and controlled in a range from 1 to 500 [ms] (when Sync mode is disabled). The value can be adjusted by dragging the up-down mouse pointer above the digits representing the consecutive decimal positions on the display.

Tap function

Tap is used to set the delay time "by ear" by clicking Tap rhythmically. The plug-in measures the time between the consecutive clicks, averages it and sets it as a new delay time. This function is also available when tempo Sync is enabled or disabled.

Tap button

Host tempo synchronization

Sync toggle button:

Sync button

This activates / deactivates the synchronization of the Time grid with the host (DAW) application tempo. When enabled, the delay is represented as a Rhythmic value (in tempo-dependent units) consisting of a Note value and a Rhythmic modifier. Note, when this mode is active the Time grid value is controlled in a different manner and the look of the Time grid display changes slightly.

Time Grid section when Sync is active

Note values

The Time Grid Note value can be adjusted by dragging the up-down mouse pointer over it;

Available values are: 1/8, 1/16, 1/32 and 1/64

Rhythmic modifiers

Clicking a Rhythmic modifier selects it:

There are 3 possible values to choose from:

• Full – Effective delay value is equal to set Note value.
  • Tri - Effective delay value is equal to 2/3rds the duration of set Note value.
  • Dot - Effective delay value is equal to 3/2nds the duration of set Note value.

Delay lines

Tekturon has 16 delay lines - each with its own feedback loop and effect chain processing the signal output from the loop:

    style D fill:#ccf,stroke:#333
    style I fill:#cfc,stroke:#333

Individual Delay line in Tekturon

A single delay line is fed from the Tap. This is delayed with respect to the Dry signal by a value proportional to Tap's index value (subsequent Taps are delayed from each other by the value of the Time grid).

Delay value in the feedback loop

The feedback loop delay is expressed as the multiple of the unit delay value (the Time grid). It is set for each of the 16 delay lines independently using the bar graph display to the left:

The Bar graph display

To edit delay values first switch to the Delay view using View Selector:

View Selector

The adjustment is performed by mouse clicking / dragging the vertical bars corresponding to the particular delay lines. The vertical position of the click represents the value. The bars are arranged so the delay lines' indexes corresponding to them start from the left side of the display (1 to 16):

Delay values for all delay lines

The numeric representation of each bar is shown in the bottom row:

Delay values for all delay lines

Delay value (the multiple of the unit delay value - Time grid) can be picked from the range x1 to x16.

Shuffle

Shuffle parameter

The Shuffle parameter introduces additional delay before each even numbered Taps and reduces the delay before odd numbered Taps by the same amount:

Influence of the Shuffle parameter on the delay times.

This causes a swing effect between the bounces output from consecutive delay lines. The Shuffle parameter controls the strength of the effect.

Feedback

Feedback is controlled hierarchically. At a global level, using the Feedback parameter in the Master section affects the Feedback value in all delay lines at once:

Global Feedback parameter

It can also be adjusted locally using the Bar graph display by selecting Feedb using the View Selector:

View Selector

The local Feedback values in the delay lines can then be adjusted individually:

Individual Feedback values

The effective (actual) feedback value for a particular delay line is equal to the value of the global Feedback parameter (from the Master section) limited by the amount set locally using the Bar graph display.

Mute Tap 1 Direct Signal

Mute Tap 1 Direct Signal switch:

Mute Tap 1 Direct Signal

When enabled, the zero numbered bounce (non-delayed signal) output from the first delay line is muted. This prevents overlapping it with the unprocessed (Dry) signal. This is a useful option when Tekturon is used as insert effect in situations where the FX (dry->wet) value sets the Dry signal as well as for cases where the plug-in is used on FX send track.

Effect chain of a delay line

Multimode filter

Multimode filter is the first effect in the chain. It is controlled hierarchically:

- Globally – Influencing all delay lines simultaneously from the Master filter section where the following parameters can be edited:

Master filter section

• Cutoff frequency
• Filter Resonance
• Filter Type – Where we have following values to choose from:
• LP - Low pass filter
• BP – Band pass filter
• HP – High pass filter
• Off - Filter inactive

- Locally – Influencing each delay line individually using the bar graph display on the left side of GUI

The Bar graph display

Filter cutoff

Local (per delay line) value of the Cutoff parameter is controlled via the bar graph display from the Cutoff view selected by the View Selector

View Selector

A single bar represents the delay line's relative cutoff frequency value, a deviation from the value of Cutoff parameter in the Master section:

Digital waveform display showing a constant blue line across multiple channels with no visible text or symbols

Relative values of the Cutoff for all delay lines

Resonance

The local (per delay line) value of the Resonance parameter is controlled via the bar graph display from the Reso view selected by the View Selector:

View Selector

A single bar represents the delay line's relative Resonance value, a deviation from the value of Resonance parameter in the Master section:

Digital audio waveform display showing a constant blue line across multiple channels (no text or symbols)

Relative values of the Resonance for all delay lines

Filter type

Selecting the Filter type locally (per delay line) is performed using the bar graph display from the F.Type view selected with View Selector:

View Selector

Per delay line Filter Type

The following types can be selected:

• / HP - High pass filter
  • /BP Band pass filter
• /LP=low pass filter
• / OFF—Filter inactive

• / MF – Delay line filter type is the same as filter type selected in the Master Filter section.

Master filter section

Panning

Stereo Panning is controlled only locally – per delay line. Editing is done via the Bar graph delay from the Pan view selected with View Selector:

View Selector

Panning is controlled in the range -100% to 100% (where 0% means center of the stereo stage):

Digital signal waveform display with alternating blue and black lines over a 12-bit time axis (no text or symbols)

Panning values

Stereo spread

Stereo Spread, which is a phase shift between stereo channels, and creates the impression of widening the stereo image. It is controlled only locally – per delay line. Editing is done via the Bar graph delay from the Spread view selected with View Selector:

Spread is controlled in range of -100% to 100%, where 0% means no spread at all.

-100% delays the left channel by 12 of the Time grid value with respect to the right channel and for 100% the right channel is delayed by 12 of the Time grid's value with respect to left channel.

Mixing bus

The Mixing Bus is the final module of the Tekturon signal processing path. It is responsible for controlling the volume of each signal leaving all 16 delay lines and then mixing them together.

Mixing bus signal flow

The delay line outgoing signal Volume is adjusted via Bar graph display (the Vol view selected with View Selector parameter):

View Selector

Volume is in a range from 0% to 100% for each delay line independently:

The delay lines' output volume values

Additionally, each bar also serves as a stereo VU-meter indicating (with a pale blue color) the level of the delay line output signal.

Audible lines

At the bottom of the display is the Audible row. This shows the active delay lines (with illuminated rectangles).

Audible controls

The prerequisite for a line to be considered as active is its Volume being set to a value greater than 0%. The row is constantly displayed.

Master section

Master section

The Master Section is the final part of the processing path of Tekturon.

The Output volume controls the amplification of the output signal (in the range from -inf do +12 [dB]) The Output meter shows volume level visually. FX controls the dry/wet ratio of the unprocessed to processed signal.

Padlock allows the FX setting to be locked so the Dry/Wet ratio stays the same when loading presets. It works in toggle mode: one click locks the parameter, a second click unlocks it.

Preset Management

Preset storage

Presets, both from Factory content and user ones, are stored as files in proper locations on the disc. Each time a plug-in instance is loaded into a project, these locations are scanned and the presets found there are consolidated into a single linear structure (list) in the Preset Browser.

Browsing presets

The Preset management section (no matter what kind of preset it concerns) enables quick navigation and browsing of the preset structure:

The Preset management section

• PRESET - Displays the name of the currently loaded preset. Clicking the display opens the Preset Browser panel, allowing you to browse factory / user presets.
  • Prev / Next - Hovering over right side of the Preset display exposes the Prev / Next buttons: They allow for linear browsing of the presets list (depending on currently set filters - see sections below).
• Save ▶ - Saves current parameters as a new preset or allows for overwriting of the existing one (see sections below).

Right-clicking over the Preset display opens a context menu with two or three additional options:

• Init - Restores initial settings of plug-in parameters.
• Reload - Reloads the most recently loaded preset.
• Save - See description above.

The Preset Browser looks as follows:

The Preset Browser

There are four main parts:

• Sources - Situated in the left column, filter content Sources for displayed presets.
  • Filter - Below Sources, a preset Filter that uses the Tags system.
  • Results - List of presets (shown in the middle column) from Sources that meet criteria set in the Filter.
  • Info pane - The right column shows information about the currently selected preset(s), divided into several subsections.

If available - For some preset types this button can be hidden and accessible from the contextual menu (accessible via right mouse-click on Preset display)
If available

Sources

In this section, you can choose a Source / Source(s) that you want to browse presets from.

Preset Sources

There are two resources to choose from:

• Factory - Delivered together with the plug-in and cannot be modified (read-only).
• User - Created by the user and can be freely modified or shared with other users.

Choosing any of them will cause the results to narrow to the presets from one resource.

Filter

The section below is the Filter, which represents a preset filtering system using Groups and Tags to browse the content.

The Filter section

Groups and tags

Each Preset is described by a few common Groups. Within each of them there may be one or more Tags from a particular set.

The Filter group

Presets from the Factory resource were assigned Groups and Tags when they were created.

Groups and Tags describe the content clearly, taking into account the plug-in's purpose.

Editing of the Groups and Tags for Factory content is limited. User presets can be described with the same Groups and Tags as Factory content, or you may define additional Tags within factory Groups and even create your own Groups with your own Tags to describe your own presets.

The only limitation is that a user cannot remove factory Groups or Tags from Factory content.

Results

This is a list of presets from chosen Sources that meet the filtering criteria. The basic function of this section is to browse and load presets. It can also be used for editing, which is described later.

Preset filtering using Groups and Tags

The Filter section contains Groups of Tags. Each Group is represented by a rectangle with the Group name + set of Tags inside.

Group 2 with two tags set (Tag 2 and Tag 3)

The filtering process cascades from top to bottom. This means that all presets available in the selected Sources are filtered by selected Tags from the first Group (uppermost one), then the Group below and so on, until filtered by the last active Group (the bottom one).

Preset Filtering with the use of Groups

The result of the cascade filtering process is listed in the middle column, the Results / presets list section. You can also consider the Results list as an intersection of preset sets, found by filtering through every individual Group.

Basic Actions

Tags work as toggle buttons. Click to activate / deactivate a Tag; a gray background color means that the Tag is inactive, and orange means that the Tag is active.

Group 2 with two tags set (Tag 2 and Tag 3)

If at least one Tag in a Group is active, then the Group (filter) also becomes active, otherwise the Group chosen doesn't affect the filtering process at all.

Group operator

When a single Tag is active in a Group, only presets having that Tag set are displayed in the Results.

If two or more Tags in a Group are active, the Results depend on the Operator chosen for the Group:

A Group operator

The Operator button works in toggle mode and offers a choice of two alternative Operators for the Group:

• Any ▶- Means that a preset is shown in the Results when the preset includes at least one of the active Tags from the Group.
  • All ▶ - Means that a preset is shown in the Results only when the preset includes all active Tags from the Group.

Filter enable / disable

You can quickly enable / disable the Filter using the toggle switch in the top-most section of the Filter:

An On/Off switch for a Group Filter

Other types of filtering

Searching by name

Alternatively, you can look for a preset by entering its name or just a piece of its name into the Find preset field:

The Find preset input

The Results are refreshed on-the-fly and they work together with the other filters.

Using the X icon clears the entire field:

Filtering Favorite presets

You can mark presets as a Favorite by clicking the Heart icon while hovering on preset name ▶. You can unmark presets by clicking the icon again (toggle mode):

Setting a preset as a Favorite on the list

Logical OR between Tags in the Group
Logical AND between Tags in the Group
It's allowed for every source (factory or user)

The flag is stored globally, meaning that a Favorite preset will be accessible as such from every other instance of the plug-in ▶

Once you have your Favorite presets flagged, you can quickly filter them using the toggle button with a Heart icon on it:

Find preset ...

Favorite presets filtering

If the button is active, then only Favorite presets will be shown (considering all remaining filters).

Filtering Pinned presets

You can Pin one or more presets using the Pin icon while hovering over a preset name ☐. You can unpin a preset by clicking the icon again (toggle mode):

Preset 6

Pinning a preset on the list

Unlike Favorites, this flag works locally and it's stored with the project file (not global config), so Pins are stored individually for every instance (with total recall, so a plug-in state is recalled if saved in the context of a project).

But, similarly to Favorites, you can easily filter presets using the toggle button with the Pin symbol on it:

Find preset ...

Pinned presets filtering

If the button is active, then only Pinned presets will be shown (considering all remaining filters).

Info pane

The column to the right shows information about the selected preset or presets. It also provides access to some of the preset editing functions.

The Info pane

There's a preset name at the top.

Editing presets

You can perform certain actions on presets, such as adjusting Groups and Tags, deletion, renaming the presets as well as their export or import. One should bear in mind, however, that some operations are only allowed on user presets but not on Factory content.

Preset selection for Edit

Some operations can be done on more than one preset, so you're allowed to select more than one preset at once; in the Results section, you can choose a preset or a set of presets in the following ways:

• Click a preset - Selects (and loads) one preset from the list.
• Win ( Ctrl + Click the preset ), Mac ( Cmd + Click the preset ) - Adds another preset to an already chosen preset or a set of presets.
• Shift + Click the preset - Selects a range of presets from the last chosen preset to the preset clicked with the Shift key.
  • Right-Click on any Preset in the Results section and choose the Select All option - this selects all presets:

Tags editing

When you select a preset or presets to change their tags, click the Pencil button next the Tags section in the Info pane to enter Edit mode for the Tags:

Entering the Tag edit mode

With the Edit mode enabled, you will see all possible Groups and Tags available for the preset(s):

The Tag Edit mode

Tag buttons work in toggle mode, much like filtering. Clicking them either sets or erases a Tag for a chosen preset. If a Tag is set for a preset, it is indicated by an orange background color, whereas if a Tag is not set, it has a gray background color.

If you choose multiple presets with existing tags, Tag buttons will appear orange if a specific Tag appears in all selected presets, and gray if it appears in none.

When a specific Tag is set only for a few of the selected presets, it appears as half-gray and half-orange.

Tags appearing only in part of selection

Changing the Tag status for one or more chosen presets sets or erases this Tag in all these presets. A status change is signaled by an Asterisk to the left of a Tag.

A Tag with a status change

Tag buttons highlighted in half-gray and half-orange color (where Tag values across the highlighted presets aren't all the same) work in a three-state system when switching between states; they turn gray if you erase the Tag for all selected presets, orange if you set the Tag for all selected presets, and return to half-gray and half-orange if the selected items remain unchanged or are returned to their initial state.

Potential changes have to be confirmed using the OK / Cancel buttons at the top part of the Tags section:

Confirmation buttons in the Tags section

Author editing

When you select a preset or presets to change the Author, click the Pencil button next the Author section in the Info pane to enter the Edit mode for the Author field:
