The Eddy is a three channel stereo CV controlled mixer with sidechained compression and distortion, designed as a compact submixer. It also has normalized feedback paths for more experimental tone shaping, no-input mixing, and percussion synthesis workflows.


INPUT SWITCHES

Up position is on

Center position is inverted

Bottom position is off

Up position causes the channel to feed back without external input.

INPUT POTENTIOMETERS

Attenuates incoming CV or normalized 10V to control channel level

Unity gain at noon and approx., 2x gain fully clockwise

Input 3 has header selectable 10x gain for line level input

CV INPUTS

Goes to the associated attenuator then controls the level of the stereo channel

5V should be about unity and 10V 2x gain

AUDIO INPUTS

AC coupled stereo input channels

Left channel is normalized to right channel for mono signals

If no input is present on left channel feedback is normalized there

EDDY PEAK METER

Shows the levels of both positive and negative peaks at the output, double the number to know approximate peak to peak value (5V, 10V ,20V)

DIST out limits at 6V (12Vpp) and COMP will stop at the threshold and not clip unless the external sidechain is used

EDDY OUT SELECT SWITCH

Selects which output bus (DIST, COMP, or MIX) appears at OUT L and OUT R

IN4/SIDECHAIN INPUT

DC coupled mono input either to mix bus or compressor sidechain.

Compressor threshold is available is accesible as a trimmer on the rear of module

IN4 has a header for 4x additional gain

SIDECHAIN SELECT SWITCH

Selects if the fourth input is a mono, unity gain input, or an input to the sidechain

If SCHAIN is selected with no input then the compression will be defeated.

EDDY OUT L and OUT R

Main output selected by OUT SELECT SWITCH

     

The seperately available Cascade expander allows access to the individual VCA outputs for use as a triple stereo VCA as well as access to the feedback filter outputs and simultaneous clean, compressed, and distorted bus outputs for additional mixing and processing options.

PATCHES TO START WITH

Three Channel Mixer

•Patch inputs in INL and INR 1 - 3
•Set OUT SELECT switch to MIX
•Set input switches to top position (ON) •Listen to OUT L and OUT R
•Watch PEAK meter for clipping

Mixer with compression and sidechain

•Set OUT SELECT switch to COMP
•Set SIDECHAIN switch to IN4 to use the ouput as sidechain input
•Mix to taste
•Peak meter should never clip

Mixer with sidechain compression

•Set SIDECHAIN switch to SCHAIN
•Inject sidechain signal at IN 4
•Watch peak meter for clipping (compression will only come from external source)

Three Channel VCA

•Attach CASCADE expander module •Input signals on EDDY at IN1 - 3
•Set CASCADE SELECT switch to CH
•Listen to the output of each channel at it’s related jack on CASCADE

•Control each signal with the CV IN jacks

Feedback distortion (no input mixing)

•Set SIDECHAIN switch to IN4
•Input signal at IN4
•Remove all other inputs
•Listen to main output pair
•Turn on each channel (input switch fully up) •Raise each input slowly

•Listen to how the feedback interacts with the input signal
•Explore the different outputs

Feedback drum machine

•Remove the signal at IN4 (or replace it with a kick drum)
•Use an envelope generator (such as Boundary Layer) to send percussive envelopesintoCVIN1,CVIN2,andCVIN3 •IN1 will become a volume knob for a hi pitched sound

•IN2 will become level for a mid pitched sound such as rimshot or clave
•IN3 will become level for a bass sound

Three Channel Distorted Filter Bank

•Attach CASCADE expander module •Input signals on EDDY at IN1 - 3
•Set CASCADE SELECT switch to EQ •Listen to the output of each channel at it’s related jack on CASCADE
