USER PRESET
The amp can receive Midi messages from any Midi Footcontroller. By saving different presets, or "patches"
for different Midi Program Change Numbers, you can automatically recall a saved preset by sending the correct Midi Program
Change Number from your Midi Footcontroller. You can assign which channel and other functions are on or off, for each and
every preset. The amp allows saving up to 256 presets, using Midi Program Change Numbers 1 through 128, in two banks.
• Bank 1 is the power-on default, and Midi Program Change Numbers will recall presets in this bank.
• Bank 2 is accessible using the Midi Bank Select Message, which is Midi Control Change Number CC#0.
• Sending the amp Midi Control Change Number CC#0 with a Control Value of 0 from your Midi Footcontroller, will select Bank 1.
• Sending the amp Midi Control Change Number CC#0 with a Control Value of 1 (or greater) from your Midi Footcontroller, will
select Bank 2.
• Bank selection on the amp is semi-permanent, meaning any subsequent Midi Program Change Numbers received, will recall
a preset in the selected bank. For example; after selecting Bank 2, all subsequent Midi Program Change Numbers will recall
presets (129 through 256, which are) in Bank 2. After selecting Bank 1, all subsequent Midi Program Change Numbers will recall
presets (1 thru 128, which are) in Bank 1.
To save a preset for a Midi Program Change Number;
• Select the Midi Program Change Number on your Midi Footcontroller.
• Manually select the JP-2C Channel and other functions you would like on or off in the preset, using the amp's toggle switches.
• Engage the STORE SWITCH, and the STORE LED will illuminate briefly as an indication that the preset has been saved.
PRE-STORE "Reset" Required: Continuing with the Mesa/Boogie tradition of robust toggle switches to select the amp's channel,
and on/off functions, instead of the ever so common momentary push-button switch, requires sophisticated software algorithms that
allow Midi to control the amp at the same time. The mix of these control methods requires that toggle switches be double-actuated
before it will have an effect (be allowed to be STORED). For example; if the amp's Channel Select toggle switch has CH1 selected,
but CH2 is active (ON) as a result of a Midi preset or command, and you would like to change the channel to CH1, the amp's channel
toggle switch will need to be moved to the CH2 position, then back to the CH1 position, in order to activate it. All Features must also
be reset in this manner before the STORE toggle will commit (write) them to a Midi Program Number.
Whenever a Midi Bank Select Message or Midi Program Change Number is received on the same Midi Channel as selected by the
