v5.28 has just been released and it is another humdinger for MIDI!
Most excitingly, all the known bugs in multi-channel editing has been fixed!**
I expect that users will find novel applications of these multi-channel features: If track routing or a JSFX is used to force all MIDI playback into a single channel, then the MIDI inside the track can freely be assigned to any channel, and channels can be used as all-purpose groups that can be independently edited, similar to FL Studio's "color groups".
** There are still one or two
Feature Requests related to multi-channel editing that will hopefully soon be implemented.
