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).
