Select a synth-type lead or pad voice (see the Voice List of the separate Data List).
Turn Knob B all the way up and operate Knob A while playing for some spacey,
floating 1980's effects.
Select a voice that sounds as though it already has reverb and chorus effects applied,
and turn Knob A and Knob B all the way down to hear the "direct" sound of the
voice. You can then turn the Knob A and Knob B settings up to add extra impact and
richness to the voice.
Select a piano voice, and turn Knob B all the way up and Knob A to about the 3
o'clock position. This should give you a majestic, organ-like sound. The attack time
is quite long so play the keys and hold them to let the sound come in fully. Ideal for
slow pieces.
Select style 42, Euro Trance. Turn accompaniment on and start style playback
(pages 26–28). Set Knob B to about 3 o'clock, and Knob A to about 8 o'clock. The
overall sound of the style should be a bit muffled, with the drums emphasized for
solid rhythmic impact.
Play a style and/or arpeggio and use Knob A to adjust the tempo.
