Dear friends i would like to know if it is possible to set to zero the external input volume for a particular stage setting. My tipical use of PX5S is as stage piano (tone generator: ON, midi output: OFF)as MIDI controller of external module (tone generator: OFF, midi output: ON)As my external modules produce a little continous white noise when module is stand by, when I use PX5S as stage piano I would like to zero the external input volume of PX5S to avoid noise overlapped with PX5S. Is it possible? One possible workaround is to assign external input volume to a slider/knob for stage settings used as stage piano: it works but I lose a slider/knob...
