Okay, so I got it in the mail last tuesday, spent a week banging around on it. They keys are quite clacky, might have to see if I can fix that. Otherwise, a very nice piano and I'm enjoying it immensely. I did try testing the connector, and I couldn't get any of the four functions working besides the sustenuto pedal. I connected pins 1 and 3, and that activates the sustenuto pedal, but I could get no other functions working.

I think it's continuous, because I think I remember someone saying that it worked on a continuous scale when used with an MIDI programme, but I might be wrong. I don't think I'd need anything but half-pedal anyways, and I don't think the PX350 supports continous half-pedaling, from what I remember. I'll probably just end up using two switches, since that's the simplest way for me to do it. Does anyone see an issue with both half-sustain and sustain being depressed at the same time? Will I have to make it so the half-sustain disengages when it full sustains?

I don't have sound right now so I'll have to check the video when I get off work, but I remember several other threads where there was dust preventing the sensors from working properly. The quick fix is to blow compressed air between the keys to clear the dust out. I can't guarentee that will fix it, but it's worth a shot!

Okay, thank you! I greatly appreciate it! I'll be sure to report my results back here! One last question: For the potentiometer for the suspend pedal, how would I wire it for the half-suspend, then full suspend? there's two pins, so I'm assuming at some point it switches over from the half-suspend to the full suspend pin. I could easily bypass this by puting two switches on the pedal, one on the 1/2 position and the other at the full suspend, but that would remove the continuous functionality of the pedal.

Thank you for your response! Yeah, I have a cheap ebay universal pedal for the back input, I was hoping to come up with something that used the proprietary pedal jack. I wanted to ensure I didn't short anything out or damage the pins, so I was planning on reading the voltage of each pin individually before doing anything, to see if there was enough voltage that I should be worried. I also remember my father telling me to make a connectivity tester with a small incandecent bulb, so if there was a short it would turn the bulb on before shorting anything out. I just bought this piano, i don't want to break it just yet! I plan to build myself a stand for the piano, since I definately don't want to spend the money for a particle-board one when I have the capabilities to make one, so I wanted to try and make a pedal assembly to go with it, for half-damping abilities that won't shift under my foot. Does anyone know the specifics for the potentiometer I would need for the suspend pedal? Thank you all for your help!

Okay, thank you! I'll probably just appropriate a connector from some junk electronic, since it looks to be fairly easy to match. I'll test all the pins for current, see how much (if any) is flowing through them. At what point would it be high enough that I should be concerned? If there's no voltage or low enough voltage, I'll test connectivity between them and see what I get!

I'm recieving a PX350 in the mail, and as a broke college student who just managed to scrape together the funds to buy a used one on sale, I'm going to try and build a pedal system myself. The PX350 has a 5-pin connector for the SP-33 pedal system. I understand that this is proprietary, so I want to know if there's anything I should be aware of before undertaking this project, so I don't get sued or something? And lastly, do I have to worry about shorting anything out or damaging the piano by testing connectivity between the pins, and if so, is there any precautions I should take? Thank you for your time!
