How do I save and restore sounds with my sequencer?

Whenever you select a new patch on the JUNO-106 or change the sound manually, there are SysEx-data sent through MIDI out.
You may record these SysEx data with your sequencer(-software) and replay it later.

Check this out:
  1. Press manual
  2. Mess with the controls to get desired sound
  3. On a sequencer - select [SysEx record]
  4. Begin Recording and press [Manual] on the Juno
  5. Save file as [*.mid] (MIDI)
If you want to use it, just play the midi file.
