Anyone use a volume pedal with their P-105? I tend to do bluesy stuff, and the tracks we pick frequently have organ instead of piano. I'm WAY less comfortable in this mode, but after talking to a couple of more advanced players it seems like I might be able to use a volume pedal to bounce it up and down. (Usually i'm just using my right hand, but i suppose that doesn't have great granularity.)

Is this a pointless exercise at the lower model end like this?

It kind of looked like from the owner's manual that the extra pedal input was just for the 3-way piano-like pedal?

I just went through this, and sympathize with your need and confusion.

Two ways to go:

1. An analog "volume pedal", similar to a guitar pedal. But I think you need a _low-impedance_ pedal, not a high-impedance pedal. [That makes it "special order" for many music shops.] I think you can find them in stereo models. Just put the volume pedal in series with the Line Out (or "headphone") jack, before the PA system.

2. A combination of a synth "expression pedal" and a MIDI Solutions "MIDI Pedal Controller". I have all the parts for this, but haven't actually put things together (and programmed the MIDI Pedal Controller). That combination plugs into the "MIDI In" and "MIDI Out" jacks of the DP.

An "expression pedal" (on a synth) is a pedal that serves as a volume control. I _think_ it's usually global (affects all voices), but don't quote me.

Physically, it's a potentiometer -- three contacts, continuously variable. The end of the cable is a TRS ("stereo") 1/4" plug. The "expression pedal" jack is set up to understand that.

Most DP's don't have that jack. Most synths do. It would make our lives easier if any DP that had an "organ" voice, also had an expression-pedal jack.

PS -- that item from Sweetwater is my "option 1" -- it goes in between the Line Out and the PA system. Very simple.
