The Presets
0.7 Sliding Eko ADJUST: Slide It! 0–100
This stereo delay effect lets you dial in the perfect “feel” to match the moment. Two echoes
are produced. One is fixed on the beat. The other can be slid in musical time anywhere
in front of or behind the beat by turning ADJUST. 0-49 = in front of the beat, 50 = on the
beat, 51–100 = behind the beat. Of course, the Soft Row contains additional controls for
fine tuning the effect.
0.8 Six Trips ADJUST: EchoSlope 0–127
Rhythmic delay voices produce a six note triplet pattern. Each repeat gets progressively
louder. ADJUST controls the slope of the first six repeats. 0 = loud to soft (normal echoes),
64 = six repeats of equal loudness, 127 = soft to loud (reversed echoes).
0.9 6 StrokeRoll ADJUST: Attack 0–127
Turn a single drum hit into a six-stroke roll with this effect. ADJUST controls the attack
of the first five repeats. 0 = loud to soft (normal echoes), 64 = five repeats of equal
loudness, 127 = soft to loud (reversed echoes).
1.0 TapGated Rvb ADJUST: Gate dB 0–85
This effect uses a tempo-controlled LFO as a rhythmic gate to the inputs of a large stereo
chamber. The gate is opened every other beat for a duration of one eighth-note. Use this
to add reverb to selected beats of a stereo source. (Try this one synchronized to MIDI with
a drum machine as a source.) ADJUST controls the input levels in dB to the reverb when
the gate is closed. 0 = always open (0dB), 85 = fully closed (-85dB). The Soft Row includes
the LFO parameters so you can adjust the overall timing of the gate.
1.1 TapEkoGate 1 ADJUST: GateWidth 0–127
This effect uses a tempo-controlled LFO as a rhythmic gate to the inputs of a delay and
reverb combination. The gate is opened once every four beats for a duration of one eighth-
note. ADJUST determines the portion of the four beats in which the gate is open. 0 = open
for all four beats, 127 = open for only the first 16th note of four beats. The Soft Row
includes the LFO parameters so you can adjust the overall timing of the gate.
1.2 TapEkoGate 2 ADJUST: GateWidth 0–127
This is a variation of TapEkoGate 1 with different echo rhythms. ADJUST determines the
portion of the four beats in which the gate is open. 0 = open four all four beats, 127 = open
for only the first 16th note of four beats. The Soft Row includes the LFO parameters so
you can adjust the overall timing of the gate.
1.3 TapEkoClear ADJUST: GateWidth 0–127
This preset is similar to the two TapEkoGate presets, except that the rhythmic gate is also
patched to clear the delay voices when it opens. This allows very high delay feedback
values to be used without creating long echo trails. ADJUST determines the portion of the
four beats in which the gate is open. 0 = open for all four beats, 127 = open for only the
first 16th note of four beats. The Soft Row includes the LFO parameters so you can adjust
the overall timing of the gate.
1.4 Tap Chamber1 ADJUST: Width 0–90
This preset is a tempo controlled variation of SnareChamber. The effect is a tight chamber
with liveness that is constantly changing. The change is tempo controlled. Press Tap to
synchronize it to the beat. ADJUST controls the width of the reverb within the overall
stereo image of the effect (0 = mono, 45 = stereo, 90 = surround). Use this to open up
sampled drum mixes.
1.5 Tap Chamber2 ADJUST: Decay 0–127
This is a version of Vox Chamber with a rhythmic twist. The width of the reverb, within the
overall stereo image of the effect, is changed rhythmically by Sw 1. This change is tempo
controlled. Press Tap twice to synchronize to the beat. ADJUST controls reverb decay.
