The Presets
4.0 Pedal Swell ADJUST: FX Mix 0–100
This is a combination of four 400 ms delays, a slight amount of chorus, and just a hint of
reverb. The foot controller is controlling the left and right input levels which allows you to
get majestic volume swells. ADJUST controls the combination of delays and chorus with
reverb.
4.1 Rez Climber ADJUST: Tuning 0–60
Try this preset with dialog or unpitched source material. It is a special effect that
dynamically sweeps the resonators through the 2nd, 3rd, 4th and 5th pitches of the
harmonic series. The sweep is controlled by the AR Env, which is triggered by mono input
level. ADJUST sets the fundamental pitch for the series.
4.2 Chord Walk ADJUST: High Cut 0–50
This preset uses the resonators to generate a rhythmic chord pattern from unpitched
source material. ADJUST controls the high frequency content of the chords. The time
switches, Sw 1 and Sw 2 are used to change the chord root-note and mode and also vary
the rhythm. Listen to this effect with a simple kick, snare and hi-hat pattern as an input
source. Press Tap twice to synchronize the tempo of the effect with the tempo of the drum
pattern.
4.3 Mars Bars ADJUST: High Cut 0–50
In this preset, the resonators are used to create a truly weird and spacey special effect.
Use any continuous sound effect, dialog, or even instrumental tracks as source material.
The tuning of the resonators is swept slowly through a series of pitches by the LFO. The
resulting sound is quite unusual (an orchestra from another planet?). ADJUST controls
the overall high frequency content of the effect. Be sure to check out the Soft Row, which
contains parameters for tuning, voice assignment and more.
4.4 ModalImpulse ADJUST: Tone 0–50
The resonators in this preset are tuned to arpeggiate a modal 7th chord. ADJUST
changes the overall tone of the arpeggiated notes. The rhythm of the arpeggio is tempo
controlled. Press Tap twice to synchronize it to the beat. The effect works well with single
percussion hits (try it with kick or snare). You can change the key, scale, and root note
of the arpeggio by playing with the Pitch sub parameters in the Soft Row. You’ll also find
controls for reverb and delay there as well.
4.5 Major Minor ADJUST: Tone 0–50
This effect in this preset builds a 6-note modal chord one note at a time. Use a single
percussion hit as an input source (a slowly repeating snare hit works well). The notes in
the chord are added slowly over 24 beats. The effect is tempo controlled. Press Tap twice
to synchronize it to the beat. ADJUST changes the overall tone of the chord notes. As the
chord builds, it is changed rhythmically between major and minor scales. The root note
of the chord is also changed in a rhythmic manner. The LFO controls the rate of the build
and the major minor shift. Switch 2 controls the changing root notes.
4.6 MIDIChords ADJUST: Sparkle 0–5
This preset is driven by MIDI Note Number. Resonators follow the note in a diatonic tone
cluster. ADJUST controls the brightness of the resonators. If the audio source is the same
as the MIDI source (a synthesizer), the effect is a little like harmonization. If the audio
source is different, the effect is much harder to describe. This preset will pass audio if
there is no MIDI input.
