Here is how Midi learn works:
When you toggle the MIDI Learn switch down then back up the midi activity led stays on
and the MCV876 is in
Midi Learn
mode waiting to receive a MIDI message containing MIDI
channel information. When a message arrives (you play a note on the master keyboard for
example) , the Midi channel number is extracted, compared to the actual interface MIDI
channel and set to this new value if different. If the MIDI channel of the message is identical
to the one configured into the interface, and if the message received is a MIDI note ON
message, the interface extracts the MIDI number of the note played and sets this value as
the reference (base or lowest) note. This allows transpose of the MCV876 to any note on the
keyboard. The reference note is the lowest note the interface can play (digital zero).
Using the small Windows configuration programme available from Marc’s website you can
configure the unit to
any of the available play modes
mode as you desire.
By default
the poly midi is configured in
Poly Mode 2 with modulation wheel as the midi
CC generating CV3.
V3.06 Firmware and different Play Modes
The Poly Midi unit can be configured in these different play modes, using the windows
configuration programme mcv876v3-04.exe which is available from:-
http://m.bareille.free.fr/mcv876/mcv876.html
(a copy is included on the cd distributed with the poly midi cv unit).
