There have been many discussions on the forum about using multiple maps on one overlay. I would be a big fan of this functionality as it allows to more easily play around with different versions of an interface (major/minor scale, mpe/non mpe) kind of interfaces without having to upload new maps to the morph.
I can imagine that this will take some time to implement. In the meantime I would like to have a “disable MPE modifier”, similar to the disable pitchbend modifier. The difference would be that all midichannels will now be set to 1 (or another number). This would allow to more easily switch between playing a MPE daw like BitWig and a non-MPE daw like Ableton.
