How to adapt Pedal SP 33 to Privia 330?

[RafaelTorres]

I bought by mistake a SP33 pedal to my Privia px330 that works only with sp32.
I didn't find sp32 to buy.
When i plug sp33 to my px330, the sustain stay 'stucked on', and de pedals didn't work (of course).
So, it's possible to ADAPT SP 33 TO PRIVIA 330?

Every keyboard has one of 2 polarities - the reason your keyboard is reacting oppositely is the pedal polarity is not matching the keyboard polarity. I'm not sure if the SP33 has the switch to change polarity - if it doesn't, the SP33 and your Privia are not compatible. I recommend buying the universal M Audio SP2 - it is very durable (I use it) - and has the polarity switch enabling it to work with any keyboard.
