I recently purchased a QY700. I can't figure out how to get my keyboard to play more than one track on the QY00 tone generator at the same time.
I'd like to be able to use the QY700 for dual voice capability. Please help!!

Can you may be say what keyboard is that ?

It is a Yamaha PSR500 (I believe). I don't have it with me at the moment. When I try to use dual voice on my PSR, it does not work.

I am still not sure what you're trying to do. Are you trying to sequence your keyboard with QY700 on more than one MIDI channel or are you just trying to record QY700 tracks with your PSR500 as a master keyboard? I don't know anything about those PSR things, but is it in fact miltitimbral (i.e. can output different sounds on different MIDI channels)?

My PSR has limited multi-channel output. I'm trying to set the QY700 to set one input channel to multiple (or at least two) tone generator tracks on the QY700. That way I can play the keyboard with dual voices. I do have a Roland tone generator also. With the Roland, I can set multiple tone generator tracks to one input channel from my keyboard. Thus playing dual or multiple voices. That's what I'd like to do with the QY700.
