FireWire interface functions ........................... 19 Introduction Thank you for purchasing the Korg LIVE CONTROL MIXER ZERO4. To ensure full enjoyment of your new purchase, please read this owner’s manual carefully and use the product as directed.

Four-channel stereo digital mixer The ZERO4 is a 24-bit stereo digital mixer that supports sampling frequencies of 44.1 kHz, 48 kHz, 96 kHz, and even 192 kHz for ultra-high quality audio. FireWire audio/MIDI interface The ZERO4 is also an audio/MIDI interface via featuring two FireWire connections. By connecting your computer and ZERO4 via a FireWire cable, and you’ll be able to transfer audio and MIDI data to and from the ZERO4. Up to 8-in and 16-out channels of audio data can be transferred over the FireWire connection. Auto BPM detection An auto BPM detector is built-in, allowing you to detect the BPM of audio material on a specific channel. You can use tap tempo alone or in conjunction with auto BPM to enhance the tempo detection. (Manual BPM can also be used.) BPM Delays and other effects can be synchronized to the specified BPM. Mic preamps The mic preamp built into the MIC jack use high audio quality circuitry designed with the cooperation of Peter Watts Designs Corporation. This logo is the property of the Peter Watts Designs Corporation led by Peter Watts, a veteran designer of numerous professional audio devices throughout his tenure at the Trident Audio Corporation in the UK and as chief engineer and developer at Mackie Designs in the USA. Flexible channel selection In addition to mic/guitar/line/phono analog audio inputs, the ZERO4 also provides digital audio inputs from the FireWire interface. In addition, each mixer channel can also serve as a MIDI controller, giving you flexible control of your audio sources. EQ type selector You can specify the type of EQ. The EQ types include typical EQ curves tuned to a particular musical genre, as well as types available only with digital processing, such as filters and isolators. Fader/crossfader curve controller Parameters are provided so that you can create your own fader curves and crossfader curve. Since you can specify the fader curve separately for each channel, you can obtain the exact sharpness and play you want for the faders. The crossfader lets you smoothly transition between audio sources.

Adjust the gain of the audio input assigned to the mixer channel. Top panel TIP: If the MIC input level is too high, causing the sound to distort, press the top panel MIC GAIN switch to change the mic preamp gain to LOW.

CUE This function lets you monitor your performance through headphones without outputting it from the MASTER OUT jacks. To monitor the sound of the CUE bus through headphones, turn the monitor section MONITOR BAL knob toward the CUE position. In this state, you can leave a fader lowered but turn CUE on and use your headphones to check the sound adjusted by EQ and the channel effect; then when you’ve adjusted the sound to your liking, raise the channel fader to output the sound from the master outputs. Monitoring via CUE By turning on the CUE switch of a mixer channel, you can send its prefader sound to the CUE bus.

1. Turn on the CUE button of the mixer channel you want

sound. Use the MONITOR LEVEL knob to adjust the overall volume.

3. By turning the SPLIT switch on, you can hear the CUE

signal from the L side of the monitor, and the master output from the R side of the monitor. When SPLIT is on, the MONITOR BAL knob does nothing.

Using the equalizer to adjust the sound Traditionally, an equalizer (EQ) divides the sound into different frequency regions, allowing you to shape the tonal character of the sound by boosting or cutting the output of each region. In more modern applications, the EQ can be used as an effect, providing filter sweeps and isolator functions. The ZERO4 provides 11 different types of EQ.

1. Use the EQ SELECTOR knob to select the equalizer

type. EQ type: These are a variety of EQ types with frequency responses suitable for different styles. Choose the type that’s appropriate for your needs.

ISOLATOR type: This is a -12dB/oct isolator. It divides the input sound into frequency regions, and allows you to individually cut the sound of each region. If you turn the knobs of all regions completely toward the left, the sound will disappear completely.

7. ZERO ISOLATOR WIDE DIVIDER

FILTER type: These are filter types in which HI is an LPF and LO is a HPF. Turning HI down (toward the left) will lower the cutoff frequency of the LPF. Turning LO down (toward the left) will raise the cutoff frequency. MID operates as a peaking EQ.

2. Use the EQ knobs to control the type of EQ you selected.

Adjust the three bands (HI/MID/LO) to obtain the desired tone.

In the ZERO4, the BPM (Beats Per Minute) setting is used as the master clock for MIDI and for effects that are synchronized to the BPM. The ZERO4 has an Auto BPM function that automatically detects the BPM from an audio input source. You can also set the BPM manually. Setting the BPM manually Turn the TIME/AUTO push knob to specify the desired BPM. Setting the BPM using tap tempo Press the TAP button at least three times to the beat of the song. The interval at which you pressed the button will be calculated, and specified as the BPM value.

The channel effects are inserted into each mixer channel. You can choose from eight different effect types, and operate the TIME, MOD, FB, and FX MIX knobs to control the sound. TIME knob MOD knob FB knob FX MIX knob Effect type list LFO LPF A low pass filter whose cutoff frequency is varied by an LFO. TIME: Adjusts the LFO speed. MOD: Adjusts the depth of LFO modulation. FB: Adjusts the amount of resonance. LFO HPF A high pass filter whose cutoff frequency is varied by an LFO. TIME: Adjusts the LFO speed. MOD: Adjusts the depth of LFO modulation. FB: Adjusts the amount of resonance. PHASER An effect that creates modulation by using an LFO to shift the phase of the sound. TIME: Adjusts the LFO speed. MOD: Adjusts the depth of LFO modulation. FB: Adjusts the amount of resonance. FLANGER An effect that creates intense modulation and a sense of pitch movement. It is effective when applied to a sound that contains numerous overtones. TIME: Adjusts the LFO speed. MOD: Adjusts the depth of LFO modulation. FB: Adjusts the amount of feedback. SLICER Cuts the sound in synchronization with the BPM. TIME: Adjusts the interval at which the sound is cut. MOD: Adjusts the proportion for which sound Setting the BPM automatically Here’s how you can use the Auto BPM Counter to detect the BPM of a song that’s being input

TIME : Adjusts the delay time. MOD: Adjusts the pitch of the input audio. FB: Adjusts the amount of feedback for the pitch-shifted sound. DELAY A stereo delay. TIME: Adjusts the delay time. MOD: Adjusts the time before reaching the delay time specified by TIME. FB: Adjusts the amount of feedback. TAPE ECHO An effect that simulates a tape echo. TIME: Adjusts the delay time. MOD: Adjusts the output level. FB: Adjusts the amount of feedback. The display indication when operating the TIME knob When you operate the TIME knob, the specified TIME parameter is shown in the display for approximately two seconds. The number shown indicates the beat. For example, a beat of 1/4 (quarter note) is shown as “1.4” in the display. Limitations on the delay time Depending on the combination of the BPM synchronization setting and the TIME parameter, the TIME parameter of the channel effect may exceed the allowable range. If this occurs, the display will indicate “FULL,” and the delay time will be set to the maximum allowable setting.

6. Loop Sampler and Master Effect

The loop sampler and the master effect are connected to the SAMPLER/FX bus in series. Input channel selection and mixing The audio of the mixer channel selected by the CH SELECT switch is sent to the SAMPLER/FX bus, and will be the input signal for the loop sampler and master effect. The MASTER FX & SAMPLE MIX fader will adjust the mix balance between the sound that has passed through the loop sampler and master effect, and the sound (“dry” sound) selected by the CH SELECT switch. By pressing the CUE button, you can monitor the “wet” sound via the CUE bus even if this is set to the “dry” side. Loop sampler This is a loop sampler that lets you play the recorded sample using either Gate Play or Loop Play methods. Operating procedure

1. Specify the recording/playback time.

The recording/playback time is specified by the LOOP LENGTH knob, relative to the BPM. Use the LOOP LENGTH knob to specify the number of beats that will be recorded/played-back. For example if you set the LOOP LENGTH knob to “1/4”, the length will be one quarter-note beat. The duration of one beat depends on the BPM value. (Refer to the table. Units are seconds.) BPM

2. Using Gate Play and Loop Play.

Limitations for different sampling rates If the ZERO4 is connected to your computer, you’ll be able to change the sampling rate from the control panel of the host application or audio driver. The available number of effects and mixer channels will depend on the sampling rate you select.

Using the ZERO4 at the 192 kHz sampling rate By starting up the ZERO4 in the special 192 kHz audio mode, you can use it as a high-quality 24-bit/192 kHz 8-in/8-out audio interface. Note: When using Mac OS X, the 192 kHz sampling rate is not supported. Starting up in 192 kHz audio mode While holding down the KEEP button, turn on the power. Note: If you start up in 192 kHz audio mode, you won’t be able to switch to other sampling rates (44.1 kHz, 48 kHz, 96 kHz). If you want to switch to a different sampling rate, you must turn off the power and then turn the power on again to start up in the normal way. Limitations in 192 kHz audio mode The specifications are limited as follows when operating in the special 192 kHz mode.

• Number of channels: Four stereo channels (8-in/8-out)
• Channel EQ: Not available
• Channel effects, loop sampler, master effect: Not available Controller operation when in 192 kHz audio mode Channel Controller

A MIDI device connected to the ZERO4’s MIDI IN/OUT connectors can communicate with your computer via the FireWire connector. About MIDI MIDI stands for Musical Instrument Digital Interface, and is a world-wide standard that allows electronic musical instruments and computers to exchange a wide variety of performance-related information. About the MIDI implementation chart The owner’s manual of each MIDI device includes a “MIDI implementation chart.” This chart makes it easy to determines the types of MIDI messages that each device is able to transmit or receive. When using two MIDI devices, you can compare their MIDI implementation charts to see whether the messages transmitted by one device will be recognized by the other device. The MIDI implementation chart for this device is provided on the CD-ROM. Note: Details of the MIDI functionality are provided in the MIDI implementation, which can be found on the included CDROM. Using the ZERO4 as a MIDI controller In addition to functioning as a mixer, the ZERO4 can also be used as a realtime controller that transmits MIDI messages to control an application on your computer or an external MIDI device such as a synthesizer. Connecting to your computer

1. Install the MIDI driver.

FireWire cable, it will be detected as a “3-in/3-out” MIDI interface. In this connection, “ZERO 1” is used to communicate between the ZERO4 and the included “ZERO Edit” editor software. “ZERO 2” is used to exchange MIDI messages between the ZERO4 and your MIDI host application such as a DAW. “ZERO 3” will operate as a MIDI interface used to exchange messages with an external MIDI device connected to the ZERO4’s MIDI connectors. (☞p.22) Note: Depending on the DAW or other MIDI host application you’re using, the application may allocate all of the MIDI ports when it is started-up. If you want to use this type of application at the same time as the “ZERO Edit” editor for the ZERO4, you must start up ZERO Edit first and allow it to detect and connect the “ZERO 2” MIDI port. Then start up your MIDI host application, and you’ll be able to use the ZERO Edit software and your other application at the same time. Using the controllers of the mixer channels as MIDI controllers

1. Turn the INPUT SELECTOR knob to MIDI.

For the mixer channel you want to use as a controller, turn the INPUT SELECTOR knob to the MIDI position.

2. When you operate the knobs/switches of the selected

mixer channel, the MIDI control messages assigned to each controller will be transmitted. If you’re using a Macintosh, you don’t need to install a driver. At this time, the audio received at the LINE input jacks of the selected mixer channel will be output to the master bus. However, you won’t be able to adjust the fader, EQ, or PAN. Use the GAIN knob to adjust the volume.

2. Use a FireWire cable to connect the ZERO4 to your computer.

3. You can use the dedicated ZERO Edit editor software to

change the MIDI messages assigned to each controller. Use the included CD-ROM to install the “KORG FireWire Audio/ MIDI driver” in your computer. (☞p.24) TIP:

3. Make sure that your computer has detected the ZERO4.

4. Start up your host application.

Note: When you connect the ZERO4 to your computer via a

Note: Depending on the application you’re using, the application may display its own port name rather than obtaining the name from the ZERO4. Audio Device PortNo. Audio Input Audio Output

Note: In some cases, audio input ports number 17 and number 18 on your computer may show a port name such as “ZERO INVALID AUDIO1, INVALID AUDIO2” or “INPUT17, INPUT18.” These audio input ports are invalid, and cannot be used. Note: Depending on the application you’re using, the application may display its own port name rather than obtaining the name from the ZERO4. *1: The output locations of the audio output ports can be changed by using System Setup or the ZERO Edit application. MIDI connections In order to send and receive MIDI messages via the MIDI connectors, you will need to obtain commercially-available MIDI cables. Connect these cables between the ZERO4’s MIDI connectors and the MIDI connectors of your external MIDI device. MIDI IN connector: This receives MIDI messages from another MIDI device. Connect it to the MIDI OUT connector of your external device. MIDI OUT connector: This transmits MIDI messages from the ZERO4. Connect it to the MIDI IN connector of your external device. Installing the software Install the KORG FireWire Audio/MIDI driver and ZERO Edit software from the included CD-ROM into the computer to which you’ll be connecting the ZERO4.
