My challenge, get BIAB software accompaniment programs to work with my Roland RD300s, an older MIDI version i.e. Midi IN, Midi Out and Midi Thru plugs. I have a Roland UM-One adapter connected to the Roland RD300s and my computer. I am receiving correct accompaniment sounds via the Microsoft GS Waveable Synth computer speakers. I use a Peavy Keyboard Amp for the Roland RD300s as it does not have it's own amplifier. Verifying all connections are correct, the Roland RD300s piano sound from the Peavy Amp is correct. BUT, the accompaniment instrument sounds that I selected, are all PIANO sounds. This happens with all the selections I make and is not limited to a single selection.

Resolving this problem is appreciated. Thanks, mjp88keys@gmail.com
