Thank you, Mike, for you answer to my question. Just a couple more, please. Can I trigger a sound wav using the usb thumb drive? I know you can play back songs, but I just need to trigger a couple sound wavs. I think the organ sounds might be okay, but does the percussion work the same way a real Hammond works where if I'm sustaining a chord with my left hand, the right hand playing a melody will not retrigger the percussion until I let go of all keys? And just one more--getting back to my original question, is there a way in stage/performance/combi mode to use a button to turn on one tone while simultainously turning off another ,yet still sustaining first tone until I lift off the sustain pedal? I'm real close to picking up a Px-5S, just looking for any workarounds I might need to do in live performance using your keyboard. Thanks again.
