The short answer is, Yes. [UTILITY] > “Settings” > “MIDI I/O” > set MIDI I/O = MIDI (green). Connect a 5-pin MIDI cable from the Out of your external controller to In on the MONTAGE

Sorry, I don’t know the Arturia Keylab 61 Mk2 or it’s MIDI capability. So we can’t help you with that (how many channels can it transmit on simultaneously?)

If it transmits on more than one Channel simultaneously, you can use the MONTAGE in MIDI I/O Mode = Multi. Each MONTAGE Part is on a MIDI Channel that corresponds to its PART number. Part 1 = Ch1, Part 2 = Ch2, and so on through to Part 16 = Ch16.

Press [UTILITY] > “Settings” > “Advanced” > MIDI I/O Mode = Multi.

If however, it transmits on just one MIDI channel, you can set the “MIDI I/O Mode” = Single or Hybrid, and select a channel on which to communicate.

“MIDI I/O Mode” = Single = Allows you to use an external controller that only transmits on a single MIDI Channel to access all KBD CTRL Parts of the current Performance. As many as eight Parts, 1-8, can linked together for simultaneous play. The active (green) KBD CTRL icon denotes Parts linked to be played together from the MONTAGE keys. The MONTAGE becomes a sound module capable of sounding in response to a single input channel — all none KBD CTRL are not accessible.

“MIDI I/O Mode” = Hybrid = the same as Single, except the non-KBD Ctrl Parts are available on their correspondingly numbered MIDI Channel as individuals. This allows you to play the KBD CTRL linked Parts from one of your two keybed, while the other plays a Single program or the other non-linked are played from a sequencer.

Thank you Bad Mister, based on what am finding in the manual for the Arturia it appears it may have the ability to communicate simultaneously to 16 channels with its various modes. I'll give it a shot, and follow the steps provided to set the montage to these settings.

Fingers crossed i'll figure it out.

Thanks again for the quick response.
