ChoirDelay and ChoirVerb — polyphonic pitched ambience

The core of both patches is a sequence of three continuously recording loopers over four steps. For a given step, you can choose which voice to employ using the 3 x 4 matrix on the front page, with each looper voice’s pitch being adjustable. You can also choose whether that looper plays back forward, reverse, or forward on one channel and reverse on the other (this introduces some interesting stereo effects, a little like a ping-pong and a little like a sound being stretched across the spectrum, especially when the loop is un-pitched).

Each looper is set to play once, both to keep the sound from becoming too “busy” and to preserve the notion of polyphony, since each voice will play the recorded buffer just once. This can introduce some silences, but those silences have their own uses: at a high tempo, the patch makes for a very unique pitched tremolo, especially with the two channels playing in opposite directions. With the ChoirVerb, set the reverb mix to 100% for some interesting shimmer ‘verb sounds that can modulate between, say a fifth and an octave up (or down).

The patch is optimized for firmware 1.10 (particularly the change allowing for value modules to display negative, quantized pitches, which allows you to pitch the voices down as well as up).

Due to CPU clipping with ChoirVerb, ChoirDelay has a few features that the reverb version does not: You can set the number of steps (from 1 to 4), and there is a UI button, which will change color according to the currently playing step.

The patch is stereo throughout.

Controls:

Stompswitches:

Left stompswitch — tap tempo (due to CPU clipping, I did not include MIDI; if you want to use MIDI clock, however, I indicate in the video where to place it… although I realize now I forgot to mention connecting it to the delay tap input; the delay module is found on the second page of the patch)

Middle stompswitch, momentary — Delay: maxes out the feedback of the delay (increasing volume and adding distortion, since it employs a tape-style delay), Verb: maxes out the decay of the plate reverb, allowing you to freeze and hold notes

Front page:

3 x 4 matrix at the center of the page: Turn on the button if you want the voice (pitch controls for each voice run down the left-hand side of the patch) to be active on that step

ChoirDelay only: At the top are 4 pushbuttons; press the button you want to determine the length of the sequence; make sure it is the only button selected from that row

White pushbuttons: On either side of the 3 x 4 matrix are white pushbuttons. If the button on the left side is pushed, the voice for that row’s left channel will be reversed. Same for the right. Push both white buttons to reverse both channels; deselect both to have that voice run forward.

On the right-hand side are familiar controls:

Mix — sets the mix for the patch

Delay mix, delay feedback (ChoirDelay) — set the delay mix and feedback for the wet-side only delay

Reverb mix, reverb decay (ChoirVerb) — set the reverb mix and decay for the wet-side only reverb
