  • What is this? - By using system exclusive MIDI code, we can dump / back up all your patches & mapping settings into our JMP-1 for safe keeping while your unit is at our shop / being worked on.
  • How is this achieved? - We midi dump all data / presets from your Jump-1 unit into our JMP-1. Once all work is completed we the midi dump from our JMP-1 unit back into your JMP-1.
  • Why do I need this? - Modding, servicing and/or repairing a JMP-1 can result in potential software & switching glitches. To resolve these issues a factory reset must be performed restoring the unit to its stock factory presets. In order to save your patch & mapping settings a Midi Dump needs to performed.
  • Important - Please list "Midi Dump" in the notes section of the Mod-Form If you wish to save your data/presets.
  • Note - We do not keep midi backups on file.
