Audio, Max, a Stereo “Y” Cable, and an Expression Pedal

Audio, Max, a Stereo “Y” Cable, and an Expression Pedal: An easy path to an inexpensive MIDI expression pedal.

I’ve been using the following method to use an expression pedal in Max *without* MIDI for quite a while, with an early version in my paper How I Lost 150 lbs. thanks to Max/MSP! So thought I would share the newer version I am using as this question comes up regularly.

Nothing to download: If you are a Max user, the below is copy/compressed code, so, just copy and paste it into a new patcher. Comments are in the patch.
