Re-initializing
To re-initialize the MicroVerb 4, hold down both [STORE] and [BANK/MIDI] while
turning on the power. This will reset all User Programs and the MIDI channel to their
default values, and will recall Preset 00.
✪ Important: The Programs in the User bank are erased when re-initializing the unit this
way. Be sure you have stored these Programs into some sort of data storage device
via MIDI System Exclusive before performing a re-initialization (see Chapter 6).
