I have a Kurzweil k2661. I use a Roland RPU-3 with two of the pedals plugged into the continuous controller inputs (and the third plugged into the switch input). It works great but I don't know if it would work with your model.

But looking at the specs for the PC1SE:

Pitch wheel, modulation wheel, 4 front panel knobs, 4 front panel switches (momentary or toggle, software selectable), 1 continuous control pedal inputs, 1 dual footswitch input, mono pressure, Super Ribbon input.

It looks like it may accommodate one continuous pedal. You may need an adapter for the dual footswitch input to accommodate the other two pedals.

Hope this helps.

Looking at a previous post (http://www.forum-pianoteq.com/viewtopic.php?id=2324), it looks like people are successfully using the Roland DP-10 with newer Kurzweil keyboards, so I think there's a good chance it will work with my PC1SE. That said, I'd sure love to hear from someone else who has tried this.

I have an older Roland sustain pedal (unknown model), but it has a TS 1/4" connector, so I doubt it's continuous. I also have a Roland EV-5 expression pedal with a 1/4 TRS connector, so I could test with that (I'll try that tomorrow), but it's not a spring-loaded sustain pedal so it's not a long-term solution.

Thanks in advance for any advice/input.
