The e560 is a triple-mode effects module: thru-zero frequency shifter, phaser and ring mod. What sets the e560 apart from other DSP effect modules
is the unique carrier wave morphing feature. Traditional frequency shifters and phasers use sine waves as the carrier/modulator, but the e560 has 8 different carrier waves that can be continuously cross-faded to create never-before heard soundscapes. The 8 carriers are specifically selected to give the widest sonic palette, from simple frequency shifts to 64-note ‘pattern sequences’ to extreme harmonic content.
Three Modes of Operation:
SHIFT: A frequency shifter that can shift thru-zero with 2 simultaneous outputs, down and up. Like traditional frequency shifters, a sine carrier will generate a smooth shift but the e560’s 7 other waves will generate a vast array of harmonic content and even patterns of evolving timbral shift. Carrier waveforms: sine, triangle, square, saw, 16-point random phase, 64-point random phase, cross-modulated triangle/pulse and 3x sine.
Frequency Shift Range: 0hz to +-3000hz
RM: A standard ring modulator (4-quadrant multiplying vca) with a twist: the 2 outputs are always forced into quadrature (90 degree phase shift). The 8 carriers can produce everything from tremolo effects to gating to high degrees of distortion.
PHASE: This is an e560 exclusive mode. The audio input is applied to an 8-stage all-pass network. The 2 audio outputs are in quadrature, but in turn phase shifted from 0 to 360 degrees relative to the input. Not only that, the ‘vector’ the phase shift follows is the data in the carrier wavetable. The phase shifting can be linear (saw wave), traditional (triangle) or bouncing all over the place (64-random phase waveform).
Not only do you have full control over the effect, but also the wet/dry mix and applying either positive or phase-inverted (negative) feedback). This introduces peaking at certain harmonics or cancellation of those harmonics. Applying a slow LFO to the feedback CV can produce a wide range of constantly changing spectral content.
There are 4 CV inputs available to control the e560 in real-time. All 4 of the panel controls have a corresponding CV input.
Frequency shift range: 0hz to +-3000hz
Carrier waveforms: sine, triangle, square, saw, 16-point random phase, 64-point random phase, cross-modulated triangle/pulse and 3x sine
- Addition of five attenuator pots: one for each CV input, plus one for the signal input

Please see my post about the E580 Re-Sampling Mini-Delay for the construction details, which are practically identical.
I suggest searching for demos of the E560, of which many can be found. I’m still learning it!
