fect the sound (for example the assignments of M1..M4).
USB IN sets which incoming data is processed on the USB
connector [USB CONNECTION] with the same options as
for MIDI IN .
USB OUT sets which data is sent out on the USB connector
[USB CONNECTION]:
OFF
sends no NRPN or sysex data
NRPN
sends only internal NRPN data
SYSEX
sends only internal sysex data
NRPN+SYSEX
sends internal NRPN and sysex data
17.16 Poly chain
Here you can setup multiple MOTAS-6 devices to play poly-
phonically together. Each device must be connected in a
chain using MIDI from OUT [MIDI OUT SOCKET] of each
device to IN [MIDI IN SOCKET] of the next. When poly-
chain is ON notes received are allocated to the devices in
the chain in a round-robin fashion. All devices should be
set to have the same max devices and each device should
be set to its number in the chain.
To assist with the setup you can press
[BUTTON-LFO X FRE-
QUENCY / DECREASE]
to transmit the polychain settings to
the next device. Pressing
[BUTTON-LFO X WAVEFORM / INCREASE]
also transmits the current patch. Note that the MIDI in
and out options need to be set appropriately, see section
.
17.17 System settings
DISPLAY CONTRAST sets the display contrast from 0 to
127.
SCREENSAVER – when set to ON the display dims (to con-
trast level 0) after a certain period of inactivity.
EXT.PAGE CHANGE – when set to YES means that the dis-
played page may change to match that corresponding to
the incoming external MIDI controller NRPN data.
ALLOW UPDATES – when set to YES allows system firmware
updates to be received over MIDI/USB (note that also the
MIDI IN or USB IN must be set to receive sysex to allow
upates).
MENUS RESET – when set to YES menus return to first item
in the list instead of remembering last edited option.

17.19 Calibration
MOTAS-6 will have been factory calibrated, but sometimes
re-calibration of the internal analogue circuitry may be nec-
essary as the properties of the analogue components can
vary with time and temperature.
One of the most important calibrations is the pitch of the
oscillators. Some vintage analogue synths have a poor rep-
utation for pitch stability but with MOTAS-6, thanks to ad-
vanced design and digital control, the stability is very good.
Press 1 to calibrate all parts of the analogue circuitry, 2
to calibrate the pitch of the oscillators and analogue noise
level, 3 to calibrate the filter cut-off frequency and reso-
nance levels or 4 to calibrate the PWM offsets (so that the
50% PWM setting is a perfect square wave). Whilst the
