Polyphony Selection
The AVS-MIDI-1 continuously detects which Gate Output plugs currently have
patch cables inserted, and uses this information to automatically and dynamically
select the utilised polyphony. The highest numbered Gate Output that has a plug
inserted decides the polyphony used, regardless of whether lower numbered
Gate Outputs have plugs inserted or not.
For example, say multitimbral mode is o
ff
, and a cable is inserted into Gate Output
number 3. When receiving notes, the unit will automatically cycle them from the
fi
rst to third channels, in a manner according to the selected note distribution mode.
When a channel is not included in the current polyphony setting, the V/Oct and
Velocity outputs are then freed up for manual control via MIDI Continuous Controller
(CC) messages. If no Gate Outputs are plugged in, that means it is possible to
manually control up to 8 CV outputs via CC messages, plus the Mod Wheel and
Aftertouch CVs. Please check the MIDI Implementation Chart below for details on
which CC numbers control these manual outputs, and which Program Change
messages may also be used to choose multitimbral and distribution modes
in session without resetting the unit.
MIDI Tuning Standard (MTS)
To implement a custom scale or tuning, MTS bulk dumps are used. You can use software like
Scala to create your own tunings, or use one of the thousands of available tunings on the
internet. Send your MTS bulk dump as Sysex to the AVS-MIDI-1, and if it is received
successfully, the LEDs will shine one by one from bottom to top. Otherwise, they will all
blink three times to indicated a failed dump. After a dump is received, the uploaded scale
becomes the new scale which the auto-tune function uses to tune VCOs. This means that in
order to use the scale, you must auto-tune your oscillator after uploading the scale.
