Controls:
- a short press of the PLUS or MINUS button changes the memory bank number (each bank stores 32 presets),
- a long press (0.5 s) of the PLUS button enables/disables write protection. Active protection is indicated by the decimal point lit on the right side of the ones digit,
- pressing and holding the PLUS or MINUS button causes the memory bank number to change rapidly.
Please note that, just like with the original cartridge, each memory bank must be formatted before first use using the instrument’s appropriate function (FUNCTION → FORMAT CARTRIDGE). Otherwise, the instrument will display the message: FORMAT CONFLICT! Formatting must be performed separately for each of the 32 memory banks (by selecting the bank using the PLUS/MINUS buttons). The process may take up to few seconds.
