It may be a bit tedious making all the CC-knobs binds for MIDI sequencer mode by hand. Also, you need to keep all the hardware manuals close.
What do you want to achieve?
Players could benefit having all the needed CC presets right on the Play for all of their devices. They may be stored in separate json-like files ready to be loaded when needed. They also could store readable names, so you won’t tweak that CC94 or something knowing the parameter’s name by heart.
I think we’re asking for the same thing - but I would like to be able to store “instruments” and configurations. So if I’m using my OB-6 on midi channel 13, load that configuration from the last time I set it up. M8 tracker allows this with aligned cc codes and saved instruments. The tedium of going into the manual and digging out all the cc for every instrument means I rarely use those functions. Sitting down and recalling would be awesome.
