Thanks for your reply... The manual says its possible to plug those pedals, that I know for sure. The problem is that the manual says these pedals can be used to control some aspects of the keyboard (style variations and other stuff), but doesn't say anything about using the PK5 as Accomp Bass....

However, I searched further for the PK5 Manual, and it does say that the Bass Mode changes the MIDI Channel to 2. Back to the Roland GW-8 Manual, it says MIDI Channel 2 is "Accomp Bass", so I guess its possible, yes...

Regards
