Revolt and OPus MIDI communication

Using MIDI between OPUS and ReVolt

Seeking the ultimate fly rig? Combine ReVolt Guitar or ReVolt Bass and OPUS to discover a world of next-generation virtual cabinet emulation fused with sublime analog warmth. Together they offer virtually unlimited tonal possibilities, all packed in a made-to-move, pedalboard friendly format. Better yet, with ReVolt’s MIDI output, it is possible to send MIDI messages to OPUS for seamless integration of the two systems.

With each press on a ReVolt’s footswitch, a Program Change (PC) MIDI message is sent out of the MIDI OUT output. Connecting a TRS to TRS mini (3.5mm - 1/8-inch) jack cable from ReVolt’s MIDI OUT to OPUS’s MIDI IN permits preset changes within OPUS’s architecture.

The following details the factory default sequence for ReVolt Guitar:

  • Pressing CLEAN switch will engage preset #1 on OPUS
  • Pressing CLEAN switch again (engaging the BOOST) will engage preset #2 on OPUS
  • Pressing CRUNCH switch will engage preset #3 on OPUS
  • Pressing CRUNCH switch again (engaging the BOOST) will engage preset #4 on OPUS
  • Pressing LEAD switch will engage preset #5 on OPUS
  • Pressing LEAD switch again (engaging the BOOST) will engage preset #6 on OPUS
  • Pressing both CLEAN and CRUNCH switches (bypassing ReVolt) will engage preset #7 on OPUS

The following details the factory default sequence for ReVolt Bass:

  • Pressing CLEAN switch will engage preset #1 on OPUS
  • Pressing DIRT switch will engage preset #2 on OPUS
  • Pressing DRIVE switch will engage preset #3 on OPUS
  • Pressing both CLEAN and CRUNCH switches (bypassing ReVolt) will engage preset #4 on OPUS

It is possible to change the starting point of the first PC message sent by ReVolt - the other PC messages will commence sequentially post the designated starting point (i.e. the following 6 for ReVolt Guitar and following 4 for ReVolt Bass). For example with ReVolt Guitar, if you wish to start the sequence at PC #12, all the MIDI messages sent by ReVolt Guitar will range from PC #12 to PC #18.

To change the starting point PC Message for either ReVolt Guitar or ReVolt Bass, follow these steps:

  • Power off ReVolt
  • Press and hold the CLEAN switch
  • Power on ReVolt. The tube window will glow pink. You are now in the SETUP menu
  • Press the CRUNCH/DIRT switch 5 times. The tube window will glow purple
  • Press the LEAD/DRIVE switch to enter this section of the SETUP menu
  • The factory default setting will make the LEAD switch’s LED blink once. This indicates that the first PC message of the sequence is PC #1
  • To increase the base value, use the 3 switches (CLEAN, CRUNCH/DIRT and LEAD/DRIVE):
      Clean = -1
      Crunch = +1
      Lead = +10
      For example, if you wish to start the sequence at PC12, press the CRUNCH/DIRT channel once, and the LEAD/DRIVE channel once. The sequence will now blink once for the orange LED of the CRUNCH/DIRT channel, and twice for the blue LED of the LEAD/DRIVE channel, indicating the number 12.
