This sort of thing happened to me once (i.e., reversed the function of the sustain pedal). I figured I might have inadvertently pressed the pedal while booting up, so I unplugged the pedal, connected it again and rebooted. It's never happened since.

Thank you. It's an interesting subject. So, say, at the simplest level, a bass player could use the line/in port (no need for a separate bass amp, at least not in principle) and become part of the overall PX-5S output, as could, say, any guitar player playing through a signal processor. Putting the power of these modern signal/sound processors - input, simply, via line/in to the PX-5S - with the phenomenal creative capabilities of the PX-5S has unlimited potential.

Apologies in advance if this seems like a stupid question... I'm using a PX-5S. Output is stereo via two amps. I want to now add a microphone to this mix. Can I connect the (mono) output socket of a Boss VE-20 Vocal Processor to the (mono) Line/In input and thereby mix the output of the VE-20 with the output of the PX-5S? I Think I can (but i'm not sure). I reckon the output from, say, a VE-20 should be, in "power" terms, no different than that of any other line/in instrument (say, an electric guitar). I do realize the PX-5S is a stage piano, not a mixer per se, but can't help wonder what those Line/In ports are for and whether I can use them (and use them safely, without causing damage). Any responses would be appreciated.

Thank you.

Original. I had both these amps anyway, for guitar. It's nice to play in stereo.

I use a Roland Street and a Roland AC-33 together (left and right). Works well.
