E INITIALIZING
If your unit behaves erratically or "freezes", the first step is to power down the unit.
and power it back up again. Disconnect any cables connected to the MIDI IN jack,
and make sure that a sequencer or keyboard is not sending messages to the QS that
would make it behave erratically (such as a long stream of pitch bend messages on
16 channels simultaneously). If these steps do not solve the problem, you must re-
initialize the software. Make sure your mod wheel is all the way down before re-
initializing, otherwise the "zero" position of the mod wheel will be incorrect. To re-
initialize the QS, hold down both buttons [0] and [3] while turning on the power. This
will reset all Global parameters to their default settings, and will initialize all edit
buffers so that all Mix, Program and Effects parameters are reset to their default
settings. However, none of the Programs, Mixes, or Effects are changed when re-
initializing the unit.

HECKING OFTWARE
The current software version may be determined by simultaneously pressing
[PROGRAM] and [00]. The QS will momentarily indicate the current software version
installed in the display.
