Checking the Software Version
The current software version may be determined by holding [GLOBAL] and pressing
[PROGRAM]. The display will indicate the currently installed software version.
SOFTWARE VERSION: 2.02
Re-initializing
To re-initialize the Q20, hold down both [PROGRAM] and [COMPARE] while
turning on the power. This will reset all Global parameters to their default
settings, and will initialize the edit buffer so that the current Program is set to its
default settings (no Blocks/routings). However, none of the Programs in the User
bank or the Preset bank are changed when re-initializing the unit this way.
Total Reset
A more drastic version of re-initializing the Q20 will erase all User Programs, as
well as resetting all Global parameters. Hold down [PROGRAM], [COMPARE],
and [<BLOCK] simultaneously while turning on the power.
