I already have a feature request (and my package has not arrived yet )
Trash80 made a Max/MSP patch to set which MIDI channels one can use with mGB. This software works with Arduinoboy.
Can we have similar functionality for this adapter? The default channel numbers used are a little bit inconvenient for me.
Isn't that a function of mGB? The adaptor and also Arduinoboy forward the complete MIDI stream and mGB picks the apropriate channels. You can configure one mGB to use channels 1-4 and the other, running on a different Game Boy, to use channels 5-8. Both are connected to the same adaptor via a split cable. This should work with up to 4 Game Boys, using all 16 MIDI channels.
