Message Time
Displayed as: M sg Tim e
Initial value: 64
Range of adjustment: 0 to 127
M sg Tim e sets the time for which parameter values (and the saved value for the current
Patch) are displayed when a rotary control is adjusted. The maximum time (value = 127) is
equivalent to approx. 3 seconds.
OS version
Displayed as: Version
This is read-only data, and reports Peak’s OS (Operating System) version. This lets you
ensure that you have the most up-to-date OS installed.
Auto Calibration
Displayed as: Calibrate
Pressing the Row 3 button initiates a calibration routine which sets up the filters, VCAs
and distortion circuitry accurately. This will have been done at the factory and should not
need to be run again, but the routine has been included for good measure. The procedure
takes several minutes, and the synth should not be touched while in progress. Note that the
routine overrides the master volume control and sets it to maximum.
WARNING: The test generates various tones which will be present at the
synth’s outputs; we recommend you mute or turn off any external amplifier or
loudspeakers connected as these tones will be at full volume.
When the calibration routine is complete, the display shows:

SYNTH 3/8
VelShape 64 h
TuneCents +0
Transpose +0
Key Response
Displayed as: VelShape
Initial value: 64
Range of adjustment: 0 to 127
This parameter modifies the synth’s response to the velocity curve set on the controlling
keyboard. The default value of 64 results in a linear relationship between the velocity curve
and the synth’s response. Reducing the value will result in lighter key touches producing
a greater volume; a higher value results in the opposite. You can set the VelShape
parameter to suit your normal playing style.
Master Fine Tuning
Displayed as: TuneCents
Default value: 0
Range of adjustment: -50 to +50
This control adjusts the frequencies of all the Oscillators by the same small amount,
allowing you to fine-tune the whole synth to another instrument if necessary. The
increments are cents (1/100 of a semitone), and thus setting the value to ±50 tunes the
synth to a quarter-tone midway between two semitones. A setting of zero tunes keyboard
with the A above middle C at 440 Hz – i.e., standard Concert Pitch.
Transpose
Displayed as: Transpose
Default value: +0
Range of adjustment: -12 to +12
Transpose is a very useful global setting which “shifts” the received MIDI Note data
up or down one semitone at a time. It differs from oscillator tuning in that it modifies the
control data from a controlling keyboard rather than the actual oscillators. Thus setting
Transpose to +4 means that you can play with other instruments in the actual key of E
major, but only need to play white notes, as if you were playing in C major.
Note that Transpose does not affect Note data generated by the arpeggiator.

Assign MIDI Channel
Displayed as: MidiChan
Default value: 1
Range of adjustment: 1 to 16
MIDI protocol provides for 16 channels of data. This allows up to 16 devices to co-exist
on a MIDI network, provided each is assigned to operate on a different MIDI channel.
MidiChan lets you set Peak to receive and transmit MIDI data on a particular channel, so
that it can interface correctly with external equipment.
Local Control On/Off
Displayed as: Local
Default value: On
Range of adjustment: Off or On
In normal operation (with Local set to On), all of Peak’s physical controls are active, and
also transmit their settings as MIDI data, provided that CC/NRPN on Menu Page 5 is set
to either Transmit or Rec+Tran (see below). With Local set to Off, the controls no longer
vary any parameters in Peak’s synth engine, but still transmit their settings as MIDI data in
the same way.
Arp MIDI mode
Displayed as: Arp>Midi
Default value: On
Range of adjustment: Off or On
This setting determines how the arpeggiator handles MIDI data.
• Off: the arp responds to incoming MIDI note data, either via the MIDI IN DIN port or
the USB port. Control data is transmitted from both the MIDI OUT and USB ports.
If the note data is supplied via the MIDI IN port, it is also retransmitted from MIDI
THRU.
• On: In this setting, the arp responds to received MIDI note data in the same manner,
but additionally transmits arpeggiator note data via both the MIDI OUT and USB
ports, along with control data.
MIDI control data
Displayed as: CC/NRPN
Default value: Rec+Tran
Range of adjustment: Disabled, Receive, Transmit, Rec+Tran
With the default CC/NRPN setting of Rec+Trans, Peak’s physical controls transmit their
settings as MIDI CC or NRPN data. The synth engine itself also responds to received
MIDI CC/NRPN data with this setting. You can choose to only transmit MIDI data and not
receive it (Transmit), or to receive it but not transmit (Receive), The fourth option, Disabled,
effectively isolates Peak from any other MIDI equipment to which it is connected. See also
Local Control On/Off above. Note that CC/NRPN messages do not include Patch data,
which is handled separately as Program Change messages – see Bank/Patch.
