chapter 4: Effect parameters
Rotary Speaker — ROT
This effect was originally produced by rotating a flat piece of wood in front of the loudspeaker in
an organ. There are two rotation speeds: slow and fast.
The SPD parameter can set using a foot switch. See page 28.
SPD Speed Control OFF, SLOW, FAST
SLOW SLOW Speed 0.1 Hz ~ 5.3 Hz
FAST FAST Speed 0.1 Hz ~ 5.3 Hz
MIX Mixing Balance 0 - 1 0 0 %
0 = dry signal.
50 = 50% rotary effect 50% dry signal.
100 = 100% rotary speaker effect.
LVL Output Level - -30 dB - +6 dB Sets the output level of the effect.

Tempo Modulation — TMD
The tempo modulation effect can produce flanger, tremolo, and pan type effects. The difference
between this effect and the other flanger and pan effects is that the modulation speed can be syn­
chronized to the song tempo. This can be set manually in bpm (beats per minute), from a MIDI
sequencer or drum machine using MIDI clock messages, or by tapping a foot switch.

DEP Modulation Depth 0 - 1 0 0 %
DLY Delay Time 0.1 - 100.0 msec
The delay time before the signal is
modulated. Also affects the frequency range
that is modulated.
FB Feed Back 0 - 100%
The amount of effected signal that is fed
back into the effect.
MIX Mixing Balance 0 - 1 0 0 %
0 = dry signal.

100 = 100% flanger effect.
LVL Output Level - oo, -30 dB - +6 dB Sets the output level of the effect.
