Chapter 12, MIDI Functions

Before loading new software into your M20, always save a “backup” of the existing software in the M20 to your computer sequencer or data storage device. This will safeguard against any mishaps that could occur during the software loading process (i.e. corrupted MIDI file, equipment failure, etc.).

WARNING: If the M20 loads an incomplete update or incorrect data, the main display will show an error message. If a software load attempt fails, it is necessary to properly load the software before using the M20. The M20 will be nonfunctional until the operating system is successfully loaded. You will need to power-cycle the M20 (turn the unit off then on again) after an incomplete load. When the M20 restarts, the main display will prompt you to erase the software again. Erase the old software and re-send the updated M20 software.

For more on M20 software, see Tutorial 6 in Chapter 15.
