Like the original JamMan, the Stec Special software allows the system
to be controlled via MIDI program change messages. Using program change
messages can be extremely handy if you already use a MIDI foot controller
to control other pieces of gear. Version 0.4 and higher of the software
allows the mapping of the program changes messages to be custom configured
for your set up. There are actually 3 MIDI maps which can be used with
the new JamMan software:
| Map # | Descriptions |
| 0 | The Chuck Map (as suggested by Chuck Swicky) |
| 1 | Bob's New Map |
| 2 | The programmable map |
| 3 or > | The default map (shown below) (an expanded version of the map used in software versions before 0.4) |
The Default Map
The assignments of program change messages in the default map is based
on MIDI foot controllers which are organized in pages of 10 (like the Lexicon
MPX R1). With these types of foot controllers, the first page provides
access to the various "Functions" of the JamMan while the second page handles
channel and page selection. Wherever possible, the map matches the original
JamMan, there's just a lot more here. Note that both "0 based" and "1 based"
program numbers are listed (MIDI program change messages start at program
0 but some foot controllers call it 1 and call 1, 2, etc...):
| 0 based | 1 based | Assignment |
| 0 | 1 | Tap |
| 1 | 2 | Loop Reset |
| 2 | 3 | Bypass |

Map 2 (programmable map)
This map can be configured by sending sending the system MIDI controller
values. For the sake of editing, the program change messages (0-29) are
mapped to continuous controllers (51-81). To change the function that is
assigned to program change 0, for instance, you would send controller 51
to the JamMan. The data value of the controller defines the function the
program change 0 will perform (when Map 2 is selected). The data values
you use are the values from the default map above. If you wanted program
change 0 to toggle Slap on and off, for instance, you'd send controller
51 to the JamMan with a value of 8.
If you press STORE after making changes to the programmable map, the modified map will be saved.
The following is an example of a typical MIDI foot controller being used to control a JamMan with the Stec Special software installed:
