The Stec Special ROM for the JamMan provides precise control of most
system parameters via MIDI using continuous controller messages. MIDI control
systems (foot controllers, sequencers, etc..) can use these messages to
control the operation of the system in real time. Refer to the table below
for details on controller assignments to system parameters.

0 through 10 use continuous values from 0-127. Any value sent to 19 through 33 will select the channel or page. Transitions from 0 to 127 toggle the functions for 19 to 33. This is a real rough quicky system.
