KORG DS-1H

Hello,
I have a question: my friends gifted me a new sustain pedal, a Korg DS-1H, but the problem is that I own a Yamaha PSR-E213 and it doesn't work on this. Is there anyway to fix this problem?

Hello.
When a Yamaha pedal is not presses, it's actually shorting out the signal. When a KORG pedal is not pressed, it's not doing anything.

So if you want to use a KORG pedal on your Yamaha, you will have to rewire the KORG pedal to work backwards.

Unless your Yamaha has the means to flip it's polarity from a menu. All KORG keyboards can do this.

Regards
Sharp

I tried that way, but anytime I press the pedal, it doesn't switch signal. It keeps sustained if I plug it when keyboard is ON and even if I press, nothing changes.

The KORG pedal is not a simple sustain pedal. There is voltage resistance to support Half Damper.

So, you need to really talk to people on a Yamaha forum and find out how Yamaha wire up their pedals so you can rewire the KORG one.

Half damper switch jacks usually have two black rings (TRS - stereo type) in order to send three types of signal to the receiving input jack.

Bottom line is that you need a pedal that conforms to what the Yamaha is looking for, which would appear to be a regular (one black line on the jack) pedal switch. Many pedals have a polarity feature (switch on the pedal case) that will change polarity of the pedal to match the manufacturer standard.

As Sharp noted, Korg and Yamaha are opposite polarity in standard configuration. The other main difference is between physical styles -- piano (lever), clam shell and stomp box momentary switches. Piano style pedals are now in the $60 range. Roland has several options for the stomp box type including single and double versions (handy for multi synth setups) from around $30 to $50. Luckily, clamshell style pedal switches are the least expensive - ~$20US or less - cheap enough to have one for playing and one in reserve if the other craps out.
