Hi, thinking about buying the QS81. Never had a synth before. My burning question that no salesperson has been able to answer:

I need to know if you can use the sliders to mute individual voices in a mix. And then can you assign a pedal to a slider so that you can mute 1 voice of a mix with the pedal. So for example if I have a strings and piano mix, can I mute the piano sound so that I only have strings playing. I play music that has strings/piano in one measure and strings alone in the next measure.

Thanks much for any information.
