Your First Session With The QuadraSynth Plus: Chapter 2
QuadraSynth Plus Piano Reference Manual 17

Playing the Demo Sequence

The QuadraSynth Plus has a built-in demo sequence which demonstrates
the wide variety of sounds this amazing instrument is capable of
generating. In order to get the full effect of the demo, we recommend
that you connect both the LEFT and RIGHT outputs to your sound
system, or listen on headphones.
To play the demo sequence:
¿Hold the [GLOBAL] button, and press [MIX].
The upper-right display will read “Playing Demo. Press MIX to stop.”
¡Press [MIX] to stop the demo.
There will be no MIDI OUT messages during the demo, and the
keyboard will be disabled.

Playing Specific Sections of the Demo

The demo sequence is currently comprised of four sections. Any
of these sections can be played directly, without listening to the
sections preceding it. This can be done by holding [GLOBAL]
and pressing one of the Quad Buttons [1] – [4] buttons which
corresponds to the section you would like to hear.
Enabling General MIDI Mode
If you are using a General MIDI sequencer, and/or playing a sequence that is
programmed to take advantage of General MIDI, turn the “General MIDI”
function in the QuadraSynth on.
To turn the General MIDI function on:
¿Press [GLOBAL].
The display will now be in Global Edit Mode.
¡Press Quad Button [2].
This selects the General MIDI parameter in the display.
¬Press the VALUE [] button.
This turns on General MIDI mode, and automatically puts you into Mix Play Mode with
Mix 00 of Preset Bank 4 selected.
For more information about General MIDI, refer to the the MIDI Supplement in
Appendix B.
