TLDR: Having complete control of the midi channel of every single note would make the Artiphon infinitely more powerful for ambi-instrumentalists.
My suggestion is to be able to have control of what channel every note on the instrument sends out. Just like you can control the note value (C-D-E-F-G-A-B) and number it, it would be very powerful to be able to control the midi channel of each note too. This would probably have to be preset specific, so I hope it is possible.
One of the main selling points of the Artiphon is it’s multi instrumentalist properties, but I also think it has the potential to be one of the most powerful midi controllers for playing multiple parts/instruments at once.
What I’m talking about is playing a drum beat on the bridge with the right hand and play chords or bass on the fingerboard with the left, or playing a slow pad with your left hand while playing solo lead with a completely different sound with you right hand.
I could even see dividing the fingerboard up in different parts for different instruments throughout a live performance for minor parts or just throwing in a sound effect or two.
I did manage to get finger-drumming while playing the neck working by blocking midi notes with a plugin on my drum vst and making sure I wasn’t playing those notes with my left hand, but it is cumbersome at best, but the result was glorious none the less.
Making the bridge send out on midi channel 1 and the rest of the strings in tap mode on channel 2 or 2-7 would open so many doors for live usage that it is hard to quantify.
