Here is a retired university professor playing his electronic accordion. I know him personally and I live about 2 hours from him. I use his programming in my accordion,too. Every sound is from the accordion itself and every part is played live. No sequencer or backup involved though I heard people say that the accordion may be considered as the first arranger because you press one chord button and it can play major, minor, diminished, or in some rare cases augmented chords.

I don't contribute much here because I am not much of an arranger player but I like hanging around here because members seem to be very knowledgeable in various areas and also pretty level-headed even in heated religion/politics discussions. I hope you enjoy the video.
