How can I add a mod wheel?

Depending on how much of a geek you are, you can always build yourself one in the environment: Simply create a new fader object and set it's output to 1 1. Of course, a pedal would probably also do the trick (in conjunction wit the odd transformer object, methinks), but then how many of you out there can actually claim you built your own Mod Wheel??! :-p

Never having used a pedal, I can only guess, but here goes:

First make sure your your pedal is plugged into your keyboard and your key board into your computer.

Then create a physical in object in the environment if there isn't already one there.

Next, attach a monitor object to the sum output of the physical in object and try using your pedal. You should see the monitor respond accordingly, displaying series of 3 numbers. Pay close attention to those numbers.

Now hook up the output of your monitor to a tranformer object and set the transformer's mode of operation to 'apply operation and let non corresponding values through'. Then set the transformer condition section to Control and the first 2 numbers to those your monitor outputs, leaving the 3rd field as thru.

Set the operation section to Control, fix 1, fix 1, again leaving the third field blank, and hook the object up to the instrument you want to control, or better still to the seq input.

That should be just yummy!

you could use software to do controller re-mapping

Or you could buy a cheapo M-Audio oxygen 8 that has a mod wheel and 8 programmable knobs to send out the controllers of choice.
