that's probably what I'll end up doing. Though m-audio has a 88 weighted controller for a little over $500. But I am married to my yamaha. I have to be faithful! I am no adulterer.

Kai's got the right idea I think. I've got a little 2-octave M-Audio too. It can be connected over USB and will probably sit on your master keyboard. Seems like the cheapest way to do it, and you can stay faithful to the Yammy...

Does anybody see a reason why this wouldn't work?

You would need a compatible M-Audio keyboard as this pedal is 1/4" jack and not USB. Now an assignable USB controller pedal... I don't know of any, but then I haven't really looked. I would buy one!

In your sequencer program, can you map other controllers onto modulation control? I am in the situation where my Roland piano has only the useless pitch/mod lever, and you can't leave the mod at maximum. I am planning on setting up a real time transformer in Logic to turn one of the 4 volume sliders into a modulation slider instead.

This may not be the best solution, but here's something I came across the other day:

(Look under midi utilities.)

It's a dx plugin that allows you to use your mouse to control CCs.

Well spotted. Shame I am a mac user though. As it happens, I mapped my sustain pedal to send max modulation. This works really nicely, since, with the portamento samples, it is quite intuitive to slap down the pedal to activate the slide between notes.

I wrote m-audio and they said it's compatible with my yamaha, I've been trying to figure it out though and have had no luck.

I feel like such a boob. I just realized that you can simply drawn in the modwheel data. F a modwheel!

you can, but sadly not in real time. Unless you use a crayon or something.

I don't mind that, I'd imagine that I would need to edit anyway...
