$1,500 from Peter at AOR- got email from him this morning and gave him the link to Master. He made the unit himself; I have borrowed it to try out in the past. He can't compete with bulk production pricing. this is the only one.

Jerry- is that the stand alone unit as opposed to the one that mounts on the keyboard that I previously pictured? Both are same price from Master.

Below is AOR unit. It is mechanical, so it has the same FEEL as the bass mechanism on a real accordion as opposed to made with switches. It can also be re-set for different MIDI output channels.
