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 of 127) is
equivalent to approx. 3 seconds.
OS version
Displayed as: Version
This is read-only data, and reports Summit’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 4 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/V
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 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
Initial 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
Initial value: +0
Range of adjustment: -12 to +12
Transpose is a very useful global setting which “shifts” Summit’s keyboard up or down
one semitone at a time. It also applies the same “shift” to received MIDI Note data, so if
you are playing Summit from a master MIDI keyboard or controlling it from a sequencer,
you can still use transposition. Transpose differs from oscillator tuning in that it
modifies the control data from the 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.

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.
Assign MIDI Channels - Part A
Displayed as: PartA Chan
Initial value: 2
Range of adjustment: 1 to 16
Summit’s bi-timbral architecture effectively means it comprises two independent
synthesisers, one for each Part. When working with Multi Patches, you can configure it
to receive and transmit MIDI data for each of the two Parts on separate channels, for the
greatest flexibility of interfacing with external equipment.
PartA Chan lets you select which MIDI channel is to be used for MIDI data relating to
Part A.
No data is transmitted or received on the Single MIDI channels when Summit is in Multi
Patch mode. How Summit handles MIDI data in and out in Multi Patch mode is further
modified by the MULTI MODE in use. See page 46 for more details.
Assign MIDI Channels - Part B
Displayed as: PartB Chan
Initial value: 3
Range of adjustment: 1 to 16
PartB Chan lets you select which MIDI channel is to be used for MIDI data relating to
Part B. In all other respects, it operates described for as PartA Chan above.
Assign MIDI Channels (Global)
Displayed as: Globl Chan
Initial value: 3
Range of adjustment: 1 to 16
The Global MIDI channel should be used in Single Patch mode. No data is transmitted on
the Global MIDI channel when Summit is in Multi Patch mode.
