ECHOZ Manual

Mode

Description

This is a single head style tape echo with mono output similar to the earliest tape units. The maximum delay time is tuned for shorter rhythmic, slapback and associated effects.

Controls

TIME	Delay time
FILTER	Cutoff of bandpass filter
FEEDBACK	Amount of feedback into the delay line

Mode

Description

A pair of delays where the input feeds the left channel and the output of the left delay feeds the input of the right delay. The feedback is taken from the output of the right side. Both delays have the same delay time for easy rhythmic effects.

Controls

TIME	Delay time
FILTER	Cutoff of bandpass filter
FEEDBACK	Amount of feedback into the delay line

Mode

Description

A three head Echo in the style of some famous 70s units. The three heads are continuously blended between using the Filter control. The output is stereo.

Controls

TIME	Delay time
FILTER	Cutoff of bandpass filter and mix of 3 heads
FEEDBACK	Amount of feedback into the delay line

Mode

Description

The Filter control also switches between combinations of the 3 heads (1+2, 1+3, 2+3, 1+2+3). Note that there may be slight jumps in the sound when switching. Stereo output.

Controls

TIME	Delay time
FILTER	Cutoff of bandpass filter and switching between heads
FEEDBACK	Amount of feedback into the delay line

Mode

Description

Like the Mono Echo in program 1, but with a stereo Chorus after the delay. The speed of the Chorus increases as the Filter control moves to high pass.

Controls

TIME	Delay time
FILTER	Cutoff of bandpass filter and chorus rate
FEEDBACK	Amount of feedback into the delay line

Mode

Description

Adds Diffusion to the input and echo repeats creating more of a detuned wash to the sound. The diffusion is modulated by internal LFOs for detuning/chorusing and the output is in stereo.

Controls

TIME	Delay time
FILTER	Cutoff of bandpass filter
FEEDBACK	Amount of feedback into the delay line

Mode

Description

An internal LFO modulates the delay time slightly to give some wobble chorus/vibrato to the sound. The modulation rate is tied to the Filter control and speeds up as the filter cutoff increases. Both the Feedback amount and Delay time influence the depth of the wobble: High feedback increases the wobble effect as does shorter delay times. Mono output.

Controls

TIME	Delay time
FILTER	Cutoff of bandpass filter
FEEDBACK	Amount of feedback into the delay line

Mode

Description

Stereo Ping Pong delays with internal LFOs modulating the delay time. Each side has a different modulation rate that increases as the Filter control is raised. Feedback and delay Time also change the depth of the modulation. Stereo output.

Controls

TIME	Delay time
FILTER	Cutoff of bandpass filter
FEEDBACK	Amount of feedback into the delay line

Mode

Description

A simple mono delay line with a low pass filter in the feedback path to roll off the high end of repeats. This program has the longest single delay time of any ECHOZ programs.

Controls

TIME	Delay time
FILTER	Cutoff of bandpass filter
FEEDBACK	Amount of feedback into the delay line

Mode

Description

Two delay lines, Left and Right. Input enters the Left delay line and is output to the Left output and also the input of the Right delay line. The output of the Right delay line is fed back into the Left input. The effect is the echo bouncing from Left to Right and back again.

Controls

TIME	Delay time
FILTER	Cutoff of low pass filter
FEEDBACK	Amount of feedback into the delay line

Mode

Description

A very short mono delay that emulates early analog ‘bucket brigade delays’ (BBD). This program is designed for short flange, chorus, slapback and Karplus-Strong effects. The latter is achieved by turning up the feedback to a high level and using the delay time to set the pitch of the string pluck. Use short percussive sounds (or triggers) to excite the delay line and try it with Vocals too.

Controls

TIME	Delay time
FILTER	Cutoff of low pass filter
FEEDBACK	Amount of feedback into the delay line

Mode

Description

Mono delay lines runs into a Formant filter with 4 vowel sounds. The Filter control selects one of the vowels. The delay feedback is before the filter so setting high levels of feedback will allow modulation of the vowel type as the sound decays. Stereo out.

Controls

TIME	Delay time
FILTER	Selects one of 4 vowel sounds
FEEDBACK	Amount of feedback

Mode

Description

A dual tap delay line with 1.0x, 0.75x, 0.5x, 0.375x and 0.25x delay time taps.

Controls

TIME	Delay time
FILTER	Selects the combination of heads: 1.0x/0.75x, 1.0x/0.5x, 1.0x/0.375x, 1.0x/0.25x, 0.75x/0.375x, 0.75x/0.5x, 0.5x/0.375x, 0.375x/0.25x

Mode

Description

A multi-tap delay line with 1.0x, 0.75x, 0.5x, 0.375x delay time taps. Each tap has a bandpass filter. The Filter control selects which of the taps is used for feedback.

Controls

TIME	Delay time
FILTER	Selects one of the taps for the feedback loop
FEEDBACK	Amount of feedback

Mode

Description

A single mono delay line with stereo diffusion creates a reverberant wash as the repeats decay.

Controls

TIME	Delay time
FILTER	Cutoff of low pass filter
FEEDBACK	Amount of feedback into the delay line

Mode

Description

Multi-tap bandpassed delay with diffusion in the feedback path. Low feedback settings produce a rhythmic effect and increasing feedback turns into a more reverb like sound. The Filter control increases the modulation of diffusion so higher levels reduce the ringing of the delay feedback but can also introduce vibrato to pitched sounds.

Controls

TIME	Delay time
FILTER	Rate of modulation of the diffusion
FEEDBACK	Amount of feedback into the delay line

Mode

Description

A mono delay line into a single pitch shifter. The pitch shift is not quantized to intervals and has a range of -1 octave to +1 octave (-1200 to +1200 cents). Pitch shifting is after the delay feedback so the pitch is constant as the repeats decay.

Controls

TIME	Delay time
FILTER	Pitch shift amount
FEEDBACK	Amount of feedback into the delay line

Mode

Description

A mono delay line into a single pitch shifter. Pitch shifting is after the delay feedback so the pitch is constant as the repeats decay. The pitch shift is quantized to the following intervals: -12 -7 -5 -3 +3 +4 +7 +12

Controls

TIME	Delay time
FILTER	Selects interval
FEEDBACK	Amount of feedback into the delay line

Mode

Description

A mono delay line into a pair of pitch shifters panned left and right. Pitch shifting is after the delay feedback so the pitch is constant as the repeats decay. The pitch shift is quantized to the following intervals: -12/+12, -12/-7, -12/-5, -5/+3, -5/+4, +4/+7, +7/+12, +12/+12 (detuned)

Controls

TIME	Delay time
FILTER	Selects interval
FEEDBACK	Amount of feedback into the delay line

Mode

Description

A mono delay line into a pair of pitch shifters panned left and right. Pitch shifting is inside the delay feedback so the pitch moves up or down as the repeats decay forming arpeggio patterns. The pitch shift is quantized to the following intervals: -12/+12, -12/-7, -12/-5, -5/+3, -5/+4, +4/+7, +7/+12, +12/+12 (detuned)

Controls

TIME	Delay time
FILTER	Selects interval
FEEDBACK	Amount of feedback into the delay line

Mode

Description

A mono delay line into a pair of micro pitch shifters. The pitch shifting is fixed to a slight detune on one side and small shift up on the other. The Filter control blends between the two with all the way counter-clockwise being only downward to only upward shift on the full clockwise. Both pitch shifters are in the feedback path so the pitch will continue to rise or drop as the repeats decay.

Controls

TIME	Delay time
FILTER	Mix of downward (CCW) to upward (CW) tuning
FEEDBACK	Amount of feedback into the delay line

Mode

Description

Multi-tap delay with a single octave up pitch shifter. Based on the classic reverb ‘Shimmer’ effect the octave effect is in the feedback loop of the delay. The Filter control sets the amount of pitch shift in the feedback and combined with the Feedback control allows for a variable mix of delay and pitch shift.

Controls

TIME	Delay time
FILTER	Amount of pitch shift in the feedback loop
FEEDBACK	Amount of feedback into the delay line

Mode

Description

Multi-tap delay with a single variable pitch shifter. The taps have both diffusion and bandpass filters. Pitch shifting is not in the feedback path so the pitch remains constant as the repeats decay.

Controls

TIME	Delay time
FILTER	Pitch shift ammount
FEEDBACK	Amount of feedback into the delay line

Mode

Description

A multitap delay line with a pair of detuned pitch shifters and diffusion. Higher amounts of detuning create up/down glides. Higher feedback amounts add a reverberant wash to the repeats.

Controls

TIME	Delay time
FILTER	Detuning amount for the pitch shifters
FEEDBACK	Amount of feedback into the delay line
