2.5 Plate4 Horns ADJUST: Impact 0–100
Bright and percussive for those horn tracks needing that certain edge. Use ADJUST to
modify the attack and release characteristics.
2.6 Alley Slap ADJUST: Pre Delay 0–100
Great for any punctuated sound source — vocals, guitars, anything. Use ADJUST to
match the delay to the music.
2.7 Drum Gate ADJUST: Duration 0–70
This inverse gated preset is low on diffusion and high on attitude. Made for drums and
other high impact sources. ADJUST controls the duration of the effect.
2.8 Slope Down ADJUST: Duration 0–100
Very inverse sounding effect. ADJUST varies the length of the slope. The AR Envelope,
triggered by mono level, cranks in a downward spiraling pitch shift. Unearthly on voices.
2.9 BigBoomRoom ADJUST: BoomKnob 0–36
The Envelope followers glide the left and right post delays giving a strong modulation
effect to the reverb tail. ADJUST adds more or less boom. Use on punchy low frequency
sound sources.
3.0 Whammy Hall ADJUST: Decay 0–30
If your guitar doesn’t have a whammy bar, it does now. The AR generator is triggered from
the mono level source. The AR generator is then attached to the LFO depth which drives
the two Post Delays after the reverb. The Release constant is set rather long so that the
depth reaches full scale after 2.2 seconds. ADJUST sets the reverb time.
3.1 JetChamber ADJUST: Jet Knob 0–127
A big chamber reverb with stereo flanging on the outputs. Use ADJUST to set the amount
of “whoosh.” The rate of the flange is controlled by the LFO. You’ll find it in the Soft Row
along with the essential reverb parameters.
3.2 EnvChamber ADJUST: Jet Knob 0–127
Similar to JetChamber, but here flanging is controlled by input level. The flange effect is
most prominent when the input level drops. This lets you process drums with little or no
reverb flanging while they are active, but individual hits and fills will have pronounced
flanging during the reverb tail. This also works well with a variety of sources including
acoustic guitar and piano.
3.3 Wizz and Wazz ADJUST: Decay 0–127
This tempo driven effect has delays that whiz from left to right. FX Mix is also linked to
tempo, going slowly from delays to reverb, then abruptly back to delays. ADJUST controls
reverb decay.
3.4 Sci Fi ADJUST: Wiggle 0–127
This preset uses an LFO modulated reverb for its basic effect. ADJUST controls the depth
of the modulation. It will put a big spacious halo around unpitched sources, like drums.
Lower settings of ADJUST will work best with pitched sources, although higher settings
can yield some interesting sound effects. (Listen to a high piano note with ADJUST at
about 100 –definite science fiction material!)
3.5 Wobble Plate ADJUST: Wobble 0–30
A different type of chorus plate. ADJUST controls glide response.
