Thanks for your anwser.
What is your advice regarding my upper question? I put it hereafter:
We just bought the PX560 for my kid. But she need a 3 sustain pedal for her piano lesson. I believed in the first place that it would be easy to plug a such device on it... But now, I am reconsidering to send it back as only the SP-33 is fitting to the pedal port and is now out-of-sale...
That's a pity as it was the perfect fit for my kid (good keyboard, tons of sounds, 16 tracks...). We will then replace it by a more standard piano (like S1000 or YDP...).
Before that, I would like to have your expertise on our situation, is there a 3 sustain pedals simple solution that could let us keep this keyboard ? Could you help us, please?
Thanks a lot!
