RHYTHMIC ECHO AND DELAY EFFECTS
1.6 LatchedEkos
The inputs and outputs of stereo delays are gated on and off by
two rhythmic switches. The Latch is used to trigger the AR
envelope, which in turn alternates the left and right delay outputs.
ADJUST controls how long the inputs to the delays remain open
over a period of four beats.
1.7 X-PanEQ BPM
This effect cross-pans the inputs between independent left and
right band pass filters and adds some bright, highly diffused reverb.
The pan rate is tempo controlled. ADJUST controls the low
frequency limits of both bands.
1.8 Pan->Eko BPM
This effect pans the inputs across the stereo inputs of a reverb and
independent left and right delays, each with slightly different EQ.
The pan rate is tempo controlled. ADJUST controls the high
frequency limits of both bands.
1.9 Tempo Verb
In this tempo-based reverb effect, decay changes in tempo. Slow
tempos yield longer reverb time; fast tempos result in shorter
decay. Set tempo with two presses of Tap, or with MIDI.
2.0 Tempo Gate
This heavily gated reverb effect has duration set by tempo. Tap in
two quarter-notes to set the gate duration.

2.1 Tape Echo
This preset simulates a stereo tape echo. The echo rate is tempo
controlled. Press Tap to synchronize with rhythmic material.
ADJUST controls high frequency damping – the echoes get darker
as they repeat. The Soft Row includes parameters for adding and
reverb as well additional controls for the delays and filters.
2.2 NonLinear 1
This effect produces echoes with non linear decay. ADJUST controls
the decay slope. 0 = loud to soft (normal echoes), 64 = six
repeats of equal loudness, 127 = soft to loud (reversed echoes). In
this preset the slope is set to produce a simple reversed echo effect.
The repeat rate is tempo controlled. The Soft Row contains
parameters for controlling the stereo image, adding reverb, scaling
the repeat rate, and more.
2.3 NonLinear 2
Similar to NonLinear 1, with some additional processing. Chorus
and reverb have been added, and the delays bounce from side to
side as they repeat. In this preset the slope is set to 64 to produce
repeats of equal loudness. The Soft Row includes parameters for
controlling the stereo image, chorus depth and rate, etc.
2.4 NonLinear 3
This is a variation of NonLinear 2 with more radical processing and
an inverted slope.
2.5 Six Across
This multi-tap delay effect filters each voice to a specific bandbass
with each tap positioned successively across the panoramic
spectrum. ADJUST controls the overall spacing between the voices.
