Thanks, I believe that is what is happening, the VR is treating the pedals as a second MIDI keyboard, which is why I was thinking that a PK connection might be needed. I can split the keyboard into right and left, with separate drawbar control of each. I have the VR-730. I only have a problem when the pedals are thrown into the mix. I may try adding a MIDI keyboard in like shown in the manual, but that will defeat my purpose anyway.
My next option that I am considering is picking up a sound module, right now I am watching a Roland Sonic Cell on Ebay. I can just run my pedals into that, and will have more options for bass sounds, and the audio output can run right into the VR730 external audio input to be mixed in with the L/R out, that way I wouldn't necessarily need to go thru a mixer. When doing these types if gigs I run straight into a pair of QSC K10 speakers.
Or, I just forget the whole thing, use this keyboard for my band gigs and use my Hammond SK2 for the organ stuff, like I have been doing.
By the way, I saw your gear list on your profile...nice to know that there is another "collector" out there (but my wife thinks it is a sickness!). I was using a Kurzweil PC3, but after a few years it started giving me problems. Right now I have it sitting here, three notes are playing multiple notes when the keyboard is played, but no problem when playing it from a MIDI keyboard. I took it apart and cleaned the keybed and connections, but no luck. I hate having it sitting unused, but there aren't many places that I can find locally (Western Mass) that repair them. I want to sell it, but I would fix it first, and if I do that, then I'd most likely keep it... Liked your band videos too!
