Sounds good, but ill probaly not use any forks of the aboy code (unless you left the other modes alone). Im not a Mgb use so dont really care about that. So youll be testing midi in and direct pot to arduino pin scanning at the same time? Perhaps it would be better to just make a separate product from arduinoboy if the low hanging fruit of piggybacking mgb support doesnt work out.

Back to the actual program: Can't for the life of me figure out how to edit a loop above 00. Anyone actually get a song going in this thing?

But you dont have to worry about reading pot data, cause the midi controller already does it for you! You just have to read the midi serial data, and update the software in a timely matter. The sync problem makes alot of sense based on what I am seeing, but I also think if you are blindly using the mgb modes to pass ccs, you are running into problems with cc 1 only has a 4bit value and is scaling for the setting. CC2 seems to work better which makes sense because it has at least 16 values to work with. Please someone correct me if Im wrong, i never used mGB.

Does the analog pots even work as we are describing on the real cart? Im guessing you dont get 127 discrete values for the filter res and cutoff there either.

Midi clock data and note on/ofs are MUCH LESS data than someone tweaking a knob in realtime. I wouldnt be surprised if we are hitting a bottleneck on the gb serial port here, and it will need some sort of filter to cut down the bits we are bangin'.

It avoids them by minimizing realtime control

Seems flaky in the og rom too. The turn to 127 issue seems to not always happen on boot, but once it "looses its place" it seems to stay flaky. It seems to happen eventually on every use. Im guessing its just a calibration issue.

Im using the latest firmware for the arduinoboy from the website on a scienceguy arduinoboy (Nothing special about it, it just has a FTDI to program it, so I could use a forked MGB firmware in a pinch).

What midi CC is gb-303 expecting? Its channel 1,2,3 for each knob, correct?

Its probably 0-127 because thats the spec of a midi cc. You might have to scale the output if the adc for the pots code expects higher. I just realized that none of the mgb cc values are that high either so I dont know if this fucks the whole idea up.
