Details of each Feature
1. Better Integration with NATIVE INSTRUMENTS’ TRAKTOR Scratch.
Version 1.5 provides the ability to use time coded CDs in addition to time coded vinyl, and either can be ef-
fortlessly set up.
Simply connect your turntables or CD players to your ZERO4 and connect the ZERO4 to your computer.
* TRAKTOR Scratch is an optional component.
2. Automatic MIDI Clock Slave Function
ZERO4 can now slave to MIDI clock from host applications and hardware instruments alike.
ZERO4 recognizes incoming MIDI Clock from Firewire MIDI or MIDI input automatically, which provides
perfect sync of internal effects and the loop sampler.
When slaving to incoming MIDI clock, the BPM indicator will read “EXT”.
Additionally, if the MIDI clock signal is interrupted for an extended period, the Zero 4 will switch to the in-
ternal clock.
[Note] Auto BPM will not function when MIDI clock is received.
3. Re-trigger Loop Sampler
The new Re-trigger function enables you to reset the start point of a loop sample.
Simply press the KEEP button while LOOP PLAY or GATE PLAY is engaged.
The update also allows you to toggle between LOOP PLAY and GATE PLAY by pressing one or the other.
4. Higher gain on Line InputsA +12dB pre gain has been added to the LINE input when LINE
is selected via the INPUT SELECTOR knob.
This allows for better gain adjustment when lower level devices are connected.
In addition, the max. input level of the LINE terminal will be 10 dB.
5. The Cue balance curve has been adjusted for more consistent monitoring.
To improve cue monitoring, the level balance curve of CUE and MASTER for the MONITOR BAL knob has
been that the CUE and MASTER volume levels reach the maximum level when the knob is centered.
6. When CUE SPLIT is ON, the MASTER side of the level meter has been changed to Pre Fader.
When CUE SPLIT is ON, the master level indicator, on the right side of the master level meter has been
changed to pre (master) fader level
7. MUTE operation has been changed when AUDIO+MIDI is selected.
The MUTE operation has been changed so that the FX ON/MUTE switch can be used as a MIDI controller
by tilting it to the MUTE side when AUDIO+MIDI is selected.
With this new setting, the sound will not be muted.

Details of each Feature
1. Better Integration with NATIVE INSTRUMENTS’ TRAKTOR SCRATCH.
The system supports TRAKTOR Scratch by NATIVE INSTRUMENTS.
Connect a CD player equipped with a turntable or scratch function to the ZERO8.
Then, you can use TRAKTOR Scratch for scratching the audio files stored in your computer.
* TRAKTOR Scratch is an optional component.
2. An INPUT TRIM function has been added.
An Input Trim screen has been added in the System menu. This allows you to adjust the Pre-Gain value of
all Analog inputs independently for better gain adjustment to match each input source when a lower level
device which tends to cause noises is connected.
1 2 3
1: LINE .................................................................................................................. 0dB, +3dB, +6dB, +9dB, +12dB
Adjusts the input level of the device connected to the LINE terminal of each channel.
2: CD/LINE .......................................................................................................... 0dB, +3dB, +6dB, +9dB, +12dB
Adjusts the input level of the device connected to the CD/LINE terminal of each channel.
3: OTHER............................................................................................................... 0dB, +3dB, +6dB, +9dB, +12dB
Adjusts the input level of the devices connected to the terminals of PHONO1, PHONO2, PHONO3, MIC1,
MIC2 and GUITAR.[Note] The INPUT TRIM value is automatically set to 0 dB when TRAKTOR SCRATCH
is used. Do not change the INPUT TRIMs of the PHONO1, 2 and 3, and CD/LINE when TRAKTOR
SCRATCH is used.

3. A SEND SETUP menu has been added.
A new Send Setup menu in the System Menu allows you to set Ext. 1, Ext. 2 and Zero FX Pre or Post.
The FireWire selection provides a new level of input management, and also allows for full duplex opera-
tion on the audio channels.
Input selections can now be made from this screen while the Input knob in the FireWire Audio streaming
mode.
In essence, this means that audio can be sent to and from your computer on the same channel.

1: EXT1 ...................................................................................................................................................... PRE, POST
Sets the audio signal sent to the EXT1 destination of each channel.
PRE: The sound level will not reflect the fader position.
POST: The sound level will reflect the fader position.
2: EXT2 ...................................................................................................................................................... PRE, POST
Sets the audio signal sent to the EXT2 destination of each channel.
3: ZERO FX .............................................................................................................................................. PRE, POST
Sets the audio signal sent to the ZERO FX destination of each channel.
4: FIREWIRE ..............................PHONO1, PHONO2, PHONO3, MIC1, MIC2, GUITAR, LINE, CD/LINE
Sets the audio signal sent via FireWire when any of the Firewire options (AUDIO,AUDIO+MIDI and MIDI)
are selected using the INPUT SELECT knob for each channel.
For example, if you set the FireWire to CD/LINE and select AUDIO(FireWire) using the INPUT SELECT
knob, to the audio source connected via CD/LINE to your channel of choice will be sent PRE EQ to your
computer.
This allows for full duplex use of the Zero8, offering further processing options.
Now you can take full advantage of the processing power of your computer, building on the impressive array
of effects already offered by your Zero8!
[Note] The FireWire Send setting is effective only when the I/O setting of each channel is set to Pre EQ, Pre Fader
or Post Fader. In addition, when TRAKTOR SCRATCH is used, CD/LINE or PHONO1, 2 and 3 is automati-
cally selected. When TRAKTOR SCRATCH is used, do not change the FireWire Send setting. If the setting is
changed, restart your software.
4. A Transport button has been added to BPM page.
Transport Control Buttons now appear one the TEMPO screen, which allow you to send Start/Stop mes-
sages to any DAW host application running in slave mode.

5. Selectable MIDI Clock slave function.
A MIDI CLOCK setting page has been added to the SETUP/SYSTEM menu.
Zero8 can now slave to MIDI clock from host applications and hardware instruments alike.
ZERO8 recognizes incoming MIDI clock from Firewire MIDI or MIDI input automatically, which provides
perfect sync of internal effects.
1
1: MIDI CLOCK SOURCE ............................................................................... INTERNAL, EXT FW, EXT MIDI
Sets the MIDI clock source.
INTERNAL: The Zero8’s internal effects and operation will sync to the Zero8’s own internal clock.
With this setting, the ZERO8 transmits MIDI clock to an external device via MIDI or FW.
EXT FW: Zero8’s operation and internal effects will sync to the MIDI Clock signal via FW.
With this setting, the BPM indicator shows “EXT FW”.
EXT MIDI: Zero8’s operation and internal effects will sync to the MIDI clock via the external MIDI termi-
nal. With this setting, the BPM indicator shows “EXT MIDI”.
[Note] When EXT FW or EXT MIDI is set to the MIDI clock source, the auto BPM function will not operate.
6. All effect programs can be selected in the SEND effect mode.
PRE and POST settings have been added to the send effect settings accessible via the SETUP menu.
KAOSS-style control of various effects ? as already implemented in the Master and Channel effects - has been
added to the Send FX section as well
7. A Bypass function has been added to the parameter based (not touch-controlled) effects.
When a parameter based effect is selected (non touch-controlled) the effect can be bypassed by pressing the
HOLD button. This is a great way to audition your effect.
8. The cue balance curve has been adjusted for more consistent monitoring.
To improve cue monitoring, the level balance curve of CUE and MASTER for the MONITOR BAL knob has
been changed so that the CUE and MASTER volume levels reach the maximum level when the knob is cen-
tered.
