Using Mod Wheel as a Volume Control

["G. Peterson" <rainham@connection.com>]

Hi all, I have a question directed to the keyboard loopers out there.
I have an old midi synth I am using.  Just about everything is midi capable
except the volume slider.  I am creating and editing my performance loops
on Performer 3.6 running on an old mac se.
Is there a simple way I can select something in the performer sequencer
that will allow me to play live volume moves into the sequencer while I am
tracking/recording?

Cheers and thanks,

Gordon
