Hello everybody, yesterday I bought a Roland FP 30 used. I have a problem with the sustain pedal: it works in reverse. I know that it is caused by the reverse polarity of the pedal/piano. I have a Studiologic sustain pedal with a switch to invert the polarity, nonetheless I still have the same problem. In fact, when I switch the polarity on the pedal, the sustain is always on, with the pedal pressed and not pressed.
I tried all the combination with the pedal in/out and the piano on/off. I tried also to solder the wires of the pedal in the inverted position but nothing changes.
Conclusion: I must buy a Roland sustain pedal? Or there are some key combination to change the polarity of the sustain pedal on the keyboard?

Was the FP-30 purchased second-hand?
Did it not include a working pedal?

Unless you find something written in the owner's manual that suggests otherwise, I would recommend using a Roland pedal.

Kind reards,
James

Does your StudioLogic pedal have 2 conductors at the end of the cable? This is also know as a tip-sleeve connector. A Roland DP-10 pedal for example has 3 conductors at the end of the cable. This is known as a tip-ring-sleeve connector. If you're trying to mix the two that doesn't work because the keyboard will always have its ring-sleeve part of the circuit shorted. Please Google to find pictures for reference.

It was a long time ago and could be totally wrong but I used to have a pedal that if you pressed and held the pedal down when powering up the digital piano it used to change the polarity/functionality - long shot but have you tried that? Sorry if you have...

Thanks to all the answers.
@Kawai James: yes, it was purchased second hand in a famous music store here in Italy. The piano did not include the sustain pedal, I was a bit puzzled by that but I told to myself: "don't worry, you have 2 sustain pedals at home". You know the rest of the story

@George Smith: I've noticed the difference you're pointing

@jamiecw: unfortunately I've tried that.

Final conclusion: at 99% of possibilities I'm buying a Roland dp-10 sustain pedal.
Probably I'll buy also a case for the piano.

Thanks again for the answers

Hello JF...
Some keyboards have a global setting so that if the pedal you plug in is "switch on" when you want it to be "switch off", you can change the global setting so that the pedal will work as you want.
Some keyboards have used auto-sensing for the polarity of the pedal, so that you don't even need to change a global setting. When the keyboard powers up, it reads the sustain input (the synth is assuming that the sustain pedal will not be pressed when you power up). So it will automatically use whatever is the power-up switch position as the "off" position.
