1.6 LatchedEkos ADJUST: EchoWidth 1–99
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 ADJUST: Low Tone 0-60
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 ADJUST: DarkKnob 0–127
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 ADJUST: Liveness 0–40
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 ADJUST: High Cut 0-50
This heavily gated reverb effect has duration set by tempo. Tap in two quarter-notes to
set the gate duration.
2.1 Tape Echo ADJUST: DarkKnob 0–127
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 ADJUST: EchoSlope 0–127
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 ADJUST: EchoSlope 0–127
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 ADJUST: EchoSlope 0–127
This is a variation of NonLinear 2 with more radical processing and an inverted slope.
2.5 Six Across ADJUST: Spacing 0-100
This multi-tap delay effect filters each voice to a specific bandbass with each tap
positioned succesively across the panoramic spectrum. ADJUST controls the overall
spacing between the voices.
2.6 BandEko Rvb ADJUST: Center Fc 0–127
In this preset, the outputs of a stereo band pass filter are sent to left and right rhythmic
delays. These delays are in the reverb diffusor loop. The effect produces diffuse, highly
colored echoes and reverb. Use ADJUST to set the center frequency of the band pass
filter.
