i was able to do a little work over the weekend and have just pushed a couple of updates to the dev branch.
bumped bees version twice, to 0.6.3 with some fixes to graphic ops init/deinit, and then to 0.7.0 with MIDI input fixes that unfortunately needs to break existing scenes that use MIDI input ops.
also added BARS8 and ROUTE16, and did some bees UI tweaking. in particular you can now delete characters in scene/preset names by holding ALT while scrolling the cursor.
and finally, i did add an operator for MIDI CC output. the reason i haven’t posted a new release yet is that this still has some issues that (as i feared) arise from the MIDI driver.
for me, it pretty much works but drops output frames when TX requests overlap. so it still needs a queuing mechanism or similar - the exact solution needs a little thought to avoid a messed up interrupt-timing situation.
anyways i will keep looking at that and probably push more updates soon, but in the meantime it would be awesome if anyone with some MIDI devices and a bees build environment, could help me test the latest changes.
