Triple Pedal Solution

Here is the easiest and perfect solution to the Nord Triple Pedal Problem. Price in the USA problem that is.

Order a SL3P-D Studio Logic. It is available on Full Compass, Amazon, Thomann etc. I saw Full COmpass at $82.00. On the right sustain pedal, leave the middle wire alone, move the wire on the right terminal of the potentiometer to the left terminal which is "free", Calibrate the gear and set screw, before you reassemble the pedal ( Calibrate by testing with your keyboard).

And That is it.

This is working with my Nord Stage 2EX 88. I have not tested it on any others.

Side note: The SL3P-D has two momentary pedals with the resistors, and the right pedal is a rotary pot. It is not the 2 zone sustain with resistors that the Nord Triple Pedal has, but rewired, I am getting full , and half dampered effect on that pedal. Hope this helps and I saved a ridiculous $320. Keep in mind, you kill the pedal warranty by rewiring it.

Thanks for the tip! Might get one to try this out. Price always kept me away from the triple pedal

Hey, price in the UK problem too!
£60 is quite a saving on the Nord triple pedal.
Does the middle pedal give correct sostenuto behaviour?

I can't see how it could emulate it. You need 2 velocity switches for the sustain alone.

Using the potentiometer can partially "emulate" the behaviour and confuse the NS2 circuit that reads the sustain, the problem is that with a pot you never get an "open" (infinite resistance) condition when the pedal is up, as instead the original Nord triple pedal does.

@rlandman: have you tried to check the MIDI data produced by the NS2 to see if the CC64 provides the full 0-127 range?

@ Mr. G and MAx Piano,
Here is what I am seeing in the MIDI data.

With the pedal up it lands at CC value 22, but I am not hearing any sustain. AS I press it jumps to 64 and full down is 127. Also, yes I am getting full sostenuto effect out of the middle pedal.

The pedal is exactly the same as the NORD Triple for left and middle, and I think you are exactly correct about the emulation. BTW, inside the right part of the pedal, it is made for the POT and not for the dual velocity switches, in other words, getting the right pedal contacts and pc board from the manufacturer wouldn't be an automatic fit.

Yes, no issue at all with the middle pedal.

I thought that I would post a few more points that seem relevant:

1) To me the right pedal, just feels better, I have always felt that the included nord Fatar pedals felt flat, and bottomed out unnaturally.
2) The right pedal with the POT, does have a bit of gear noise to it ( not spring noise). Not something you would hear unless playing very softly.
3) I love the look of the pedal, and other than the logo, it looks just as the NORD Triple would look. The Gel sticker from your old sustain is not the same size as the logo sticker for the Triple pedal... too bad
4) My Genre is rock, and thus this pedal is a "nice to have" versus "had to have". The price makes me feel like I won some sort of prize. With the case, and keyboard coming in around $4K, I have no guilt about the workaround.

Good that you are happy with this alternative, but strictly speaking we should not claim that it is a substitute for all the functionality that the triple pedal has.
I am not sure how the SL3P-D Studio Logic looks inside (is it the same as VFP3/10 ?) but the triple pedal has two bubble switches for the right pedal alone. I presume that this is for velocity controlling the noise of the half pedalling and the full pedalling. I am sure maxpiano investigated this in the past.
If you could find a way to replace the pot and incorporate those two bubble switches (or just 4 simple microswitches in the right place so they trigger in the expected order according to the degree of pressing) then that might work as a complete substitute. And yes the triple pedal seems too expensive.

You are correct Mr_G, actually a VFP3/10 is the one that can more closely emulate the Triple pedal since it uses a double contact bubble switch under each pedal (requires some modification, adding resistors and cutting some circuit tracks, in any case you only have 1 bubble contact under the sustain pedal so you cannot reproduce the Nord Triple behavior 100%, particularly the half pedaling, but... quite close)

Your suggestion to add a microswitch, in case of a pot-based pedal, so that it opens the circuit when the pedal is OK too, but not so easy to do
