Paul,
Is there any chance the new ‘650firmware will play nice with the MidiBoard? Or is this too small a nit to getmy hopes up? I’m thinking that maybe along with everything else, we getlucky and this combo starts to work. I’d really like to pair up the MOTMwith that board and see what I could do with poly after-touch.

Subject: [motm] MOTM-650 info
Since I'm starting to ship out MOTM-650s, it's improtant tounderstand the issues with V1.3 FW and documentaion (or lack thereof):
a) I will send the info I have. There info is based on theEuropa mod for the Jupiter 4:
and you will see references to "push thisbutton...." but for the '650, it's a distinct menu item
b) there are 3 know "issues" with the firmware(and some minor ones)
1) you can't "flood" MIDI data to the '650, meaning blasting running status/16channels of 64 noteseach/etc. Also, it ∗hates∗ the Kurzweil MidiBoard (why, I could never figure itout). Try to 'pre-filter' MIDI data ifpossible. It's not that difficult to do.
2) Even though there menu "says so", you ∗cannot∗assign AUX outputs to CC messages unless they are the 'named' ones (like BreathController or Pitch Wheel). If you want to use the AUX outputs with yoursequencing program, just pick a named CC and it will work fine. Just becauseit's NAMED Mod Wheel doesn't mean you have to use it as such. It's just a∗name∗, not a ∗function∗ to the '650. You control where the patch cord goes :)
3) trying to drive the arpeggiators with external clock canbe erratic. Some people claim no problem, other say it locks up. MIDI clock and internal clock work great. The dualarpeggiators are VERY WELL DONE in the code as are the complicated poly voicingallocation algorithms.
Don't forget (and this is not mentioned in the docs) thereare 15 tuning tables pre-loaded for micotuning fun, and you can dump tuningtables to it.
The SW is not perfect, but it's a poor 8051 8-bit controllerwith 768 bytes of RAM running at 1MHz rate. It's doing the best it can :)
The basic MIDI-CV functions work perfectly and this ∗∗∗IS∗∗the most accurate and stable MIDI-CV ever made (tru 16-bit accuracy, <5ppmdrift).
I know someone had a really nice menu flowchart for the'650. If someone has that, please put it up and send me a copy. It was on mycrashed HD :(
