I have just today purchased Ableton Live 11 (which has MPE support) and updated the OB-6 to 1.6.6 (which also has MPE support).
I'm having an issue because the Ableton 11's external instrument device with MPE support, when set to output in MPE mode, cycles through MIDI channels 2-16, whereas the OB-6 is only listening to channels 2-7 in this new MPE mode. So this has the effect of only playing 6 notes, then skipping 9 notes, then playing 6 notes, ...
Maybe Sequential can increase the number of MIDI channels that the OB-6 will listen to, or make this range adjustable? I'm not familiar with MPE enough to know if limiting to channels 2-7 is something standard, I suspect not. There seems to be many different implementations of MPE.
Hi, the problem is not the OB-6. In MPE it is designed you have 2 zones: a 'lower zone', that uses Midi channel 1 as Master channel with the MPE member channels starting at 2 and going up, and an 'upper zone', that uses Midi channel 16 as Master channel with the MPE member channels starting at 15 and going down. The two zones allow for using two MPE systems on one MID cable (or two split zones on a keyboard). If one uses f.i. 6 channels for MPE in the lower zone, this will occupy channels 1 + 2-7. This implies the upper zone can then use a max of 8 MPE channels (8-15 + 16).
Thus the way OB-6 has set it up is correct.
I don't have ableton 11 (only 10), but somewhere in the MPE settings, look where you can set the Zone to 'lower' and the amount of member channels to '6'. Then this corresponds to the channels OB-6 listens to.
By the way, you can assign less member channels than an MPE device has voices, but never the opposite. The maximum of member channels should never exceed the maximum of voices.
