I don't have an answer - total newb here - but I do have a related question.  Setup is Montage M8x and Cubase AI on a Mac.  I'm trying to learn how to record MIDI from the synth to Cubase, and play back MIDI using the synth as the tone generator.  I've got 3 tracks of MIDI data in Cubase - drums, bass, and clavi.  USB MIDI output to synth, which is set up as a Multi/GM performance.  Track 1 - drums - is going out from Cubase on Channel 10.  In the Multi/GM performance, Part 10 is a drum kit.  Start the transport, drum sounds come out of synth.  Yay!  But... Track 2 goes out on Channel 2, and Part 2 is a bass.  Track 3 goes out on Channel 3 which is a clavi.  But BOTH instruments are played by BOTH tracks - I get both sounds for every MIDI event in both tracks (but NOT the drum track!).  And weirdly, if I put the tracks out to Channel 9 and 11 respectively, and make Parts 9 and 11 a bass and a clavi, everything works - I get only one instrument per MIDI track.  What am I doing wrong so that Parts 1-8 don't behave the same way?  

It would be helpful to place a MIDI monitor between Reaper's output and Montage's input (should be possible with a plugin or maybe Reaper or virtual MIDI cables & standalone software) in order to monitor the MIDI messages before Montage shows the "Piano Vintage" and after it displays.  The exact MIDI stream sent by Reaper would be interesting to look at.

My guess would be that there's a PC (program change) sent.  

And "Piano Vintage" is a category designation.  There's a way to show the Part names rather than the part types (categories).  You go to [UTILITY] -> Settings -> System -> "Part Display" and change this from "Type" to "Name".   There may be an easier way to toggle this on the Home screen like there was on the previous generation, but I didn't find it.

Here's a picture of the configuration screen:

The M doesn't have Part Name/Type change on home screen.

And the M doesn't have that on the Smart Morph Edit screen either. They may have intentionaly removed both of them from the M. Perhaps because changing the display type isn't something they would expect a user to be doing all the time.

The classic Montage Supplementary doc seems to show that the part name/type change functionality was added to the home screen and the smart morph screen in OS 3.5 but I don't know when that update was released.

I would hope that the M OS release would have been based on the most current classic OS available at the time but who knows?

What am I doing wrong so that Parts 1-8 don't behave the same way?  

Parts 1-8 can be keyboard controlled, part 9+ can't.  And all keyboard-controlled parts answer to all midi messages addressed to any of them.  Try disabling keyboard control on them to see if it makes a difference.

I think they just favored displaying more other things on the screen and killed the part name /category selector in favor of making room for other things and intentionally buried what they thought was a low usage feature.  Setting this to Part Name under utility wouldn't hurt anything and probably is overall more useful.

As always, if you want to campaign for bringing back the old functionality (without losing too much new features) you can ideascale that if it hasn't already been "idea'ed".

The tradition has always been to evolve without retaining everything from the past.  Sometimes this is progress and sometimes some really great stuff is left behind.  FM-X being half of the FS1R and no AWM interaction like SCM.  Half a Motif sequencer.  Etc...  

Overall, I think there's strong advancements vs. Montage classic (ignoring earlier synth) with very little compromise.  Probably MIDI implementation although that's a mixed bag itself.  Some good.  Some loss in functionality.  MIDI 2.0 in its more finalized form may tip the scales.  We're still waiting for more practical proof points - meaning a more baked ecosystem including software at every level.
