Since the Casio PX-3 and other Privia keyboards don't have foot pedal ports for volume, expression and other functions, does anyone know if there are any ways to hook up various pedals like a volume type for organs? Are there any external boxes or devices that can work as an optional way to attach pedals?

Would a volume pedal work if you ran the PX-3 through a pre-amp or mixer and ran the pedal through the mixer some how? Thanks for any help and links.

There are plenty ot stereo volume pedals available with line in / line out sockets - just place one between the piano line out and the amplifier/desk line in.

I was about to suggest MIDI. But if the PX-3 lacks the ability to assign the volume function to one of it's own pedals I doubt MIDI could help.

Try using a "volume pedal" that is designed for guitar. Send line-out to the pedal then the pedal plugs into an amp and speakers.

I think volume and expression can only be assigned to continuous pedals.
That might be the reason why it is not supported.

On the other side the PX3 is MIDI compliant and Expression and Volume are part of the MIDI standard. Check the MIDI implementation, it should be available as a separate document online.

If the pedal is intelligent - if it has MIDI- it should be possible to connect.

You can make a first try with MIDI OX and simulate the events and so test in advance if it really works.

If volume or expression is the only requirement and no MIDI recording is needed, then of course analog pedals that work directly on the audio signal would be cheaper and without compatibility problems.

As others have mentioned, you can easily place a volume pedal on the outputs of the PX-3. For tonewheel organ sounds in particular, ideally, a pedal should typically increase volume and distortion together, that requires a MIDI style expression pedal, and also requires that the patch be programmed for that function.

If you want to get really fancy, you could disable the rotary effect on the PX-3 and send the organ sound out to a volume pedal and then into a Neo Ventilator pedal, which will give you a much better Leslie sound and will have a distortion that will increase as you give it more gain (i.e. as you increase the volume with the pedal).

As for hooking up other pedals to the PX-3 to perform whatever other controllable MIDI functions you may want, something like the Behringer FCB1010 should work, you can program its two pedals to send any MIDI CC info into the PX-3's MIDI input. I guess the question would just be whether the PX-3 is set to receiver that input externally. I think it would work, but I'd be curious to hear the results if anyone has tried it.
