Oneiroi — a multi-voiced looping dream machine

**Requires firmware 1.13 to operate properly**

Oneiroi listens to your thoughts (and the audio input) and recombines them in a multi-voiced choir, whispering sweet nothings while you dream.

Okay, maybe it doesn’t do that. What it does instead is record into loops, either based on your playing style, or a window clocked by tap tempo. There are two sets of four loopers, each looper with its own pitch and reverse control. These cross-fade beween one another, so that while one loop plays, another can be recorded, and once the recording is complete, they will fade into each other.

These loopers are then output into an effects section with a low-pass filter (for taming the highs), a phaser (for adding subtle movement), a high-pass filter (for cleaning up the bottom end), and finally a reverb lite (to add space).

You can also cross-fade between the loops at will and lock them at a specific mix, to play over.

The signal path is stereo on the dry side. The loopers sum the inputs to mono, before producing a stereo image via the reverb lite.



Left — cross-fades between loops; while the loops are cross-fading they can be locked by tapping the footswitch; tapping again will release the mix (cross-fading can be controlled with the “Fade time” control)

Middle — tap tempo for the “Clocked” option; the clocked option also accepts MIDI clock, which is located on the second page, if you would like to set a clock division for MIDI

Right — locks the loops/ceases recording new loops. When this occurs, the light in the bottom right corner will be white.

Front page:

Down the left side: pitch and reverse controls for each loop.

At the bottom of the left side: a pushbutton labeled “Clocked.” When this is active, the patch will respond to a tapped window for recording, initiated by new notes being played (a silence must precede new notes for proper operation). All clocked loops will have the same length.

When the “Clocked” button is off, the patch will respond to the incoming signal and record as long as one is detected above the “Threshold” control on the top right. You can also set a “Follower release” amount: this provides a buffer between audio falling below the threshold and the looper’s discontinuing recording, which can be useful when playing phrases.

A red pixel beside the “Clocked” button will show whether the patch is recording at that time or not and can be useful for dialing in tap tempo, threshold, and envelope follower release.

Continuing down the right side, there are also controls for “Wet level” and “Dry level.”

In the middle of the patch are controls for the effects section:

LPF freq — sets the low-pass filter frequency, for controlling pitched-up loops

Phaser — a macro that adjusts the phaser mix, depth, and resonance. The value will always reflect the phaser mix, but other settings change in slightly different degrees.

Phaser tap tempo — a pushbutton that can be used to set the phaser tempo

HPF frequency — set the high-pass filter frequency, for cleaning up the low-end; between the low-pass filter and the high-pass filter a band-pass is effectively created, with the phaser in the middle

Reverb — a macro that controls the reverb lite; adjusting it will change the reverb decay and reverb mix. The value will always reflect the reverb mix, but the decay has been set to increase faster than the mix.

On the bottom are two pixels to represent the two loops. Between them is a “Fade time” control for setting the speed of the cross-fade.

    This might be my favorite Zoia patch yet, and that’s saying a lot considering your output. Thanks for your excellent contributions to this community!
