The Presets
1.9 Too Deep! ADJUST: Decay 0–40
The left and right envelope followers control the post delay glides while the AR generator
controls reverb width. ADJUST controls reverb decay.
2.0 Dyna-Hall ADJUST: Decay 0–130
A tamer version of Too Deep! No envelope chorusing. Good, beautiful, straight ahead,
and spacious.
2.1 RotoRox ADJUST: FX Mix 0-100
RotoRox crossfades deeper into two delay voices when the envelope follower detects an
absence of input. Great vocal effects for thickly-produced rock and roll. ADJUST will add
more or less reverb into the effects mix.
2.2 RotoRoomVox ADJUST: Decay 0–100
This medium large sized room continuously changes spatial width according to the speed
of the LFO which tracks the input. Faster with less input, slower with more input. ADJUST
controls reverb decay. Nice roomy effect for background vocals.
2.3 RotoRoom ADJUST: Decay 0–60
Similar to RotoRoomVox except the speed of the spatial width modulation is stable, with
the speed of the LFO constant. Room is smaller, more dense-sounding and brighter.
2.4 RotoRoom#2 ADJUST: Rt & Rate 0–60
Speed and reverb decay are tied to ADJUST. Way cool on a stinger sound effect!
Dynamically spacious and not mono compatible.
2.5 Tremolo Tap1 ADJUST: Depth 0–127
This is a basic tremolo effect with a small amount of ambience added. The effect is true
stereo. The left and right channels are processed separately to maintain the image of
stereo source material. The tremolo rate is tempo controlled (2 cycles/beat). Press Tap
to synchronize the effect with rhythmic material. ADJUST sets the tremolo depth. 0 = no
tremolo, 127 = maximum tremolo.
2.6 X-TremoloTap ADJUST: Depth 0-127
This a variation of TremoloTap1. In this preset the left and right modulation are 90° out
of phase, producing a stereo effect that doesn’t collapse in a mono mix. If the input source
is mono, the sound will seem to move from side to side. If the input source is stereo (or
two different mono sources) the left and right channels will alternately grow loud and soft.
The modulation rate is tempo controlled. ADJUST controls the tremolo depth for both
channels. 0 = no tremolo, 127 = maximum tremolo.
2.7 Panner BPM ADJUST: Pan Phase 0–1
This effect is a tempo controlled auto panner with the inputs independently panned left
and right. ADJUST allows you to set the relative phase of the input panning. 0 = in phase,
1 = 90° out of phase. In the preset, the panning is 90° out of phase. If the input source is
mono it will pan from side to side. If the input source is stereo (or two different mono
sources), the two sources will chase each other between the speakers. Set ADJUST to
0 for “normal” auto panning.
2.8 Nice Pan! ADJUST: FX Mix 0-100
This preset combines static time based delays which move back and forth in the stereo
field with a short, bright chorus plate. ADJUST varies the delay and reverb mixing. Great
for acoustic guitars.
