Introduction
'Lorelei' is a VCO (Voltage Controlled Oscillator) with quadrature sine outputs, waveshaping, and sync/cross-modulation options.
The module has three waveform outputs, all affected by the same waveshaping controls (a front panel knob and a CV input). The first offers a variable pulse width square wave. The remaining two offer waveforms based on quadrature (i.e. 90 degrees out of phase) sine waves. The waveshape control progressively turns the first sine output into a triangle-like waveform; the second sine output becomes a saw-like waveform.
The cross-modulation input is somewhat like the sync input found on more conventional VCOs, but it has more nuances of operation allowing for a wider choice of sounds.
The module is 100% analogue, using discrete transistor OTAs.

Reviews
Sound On Sound magazine (June 2022 issue - read the full review here) said
Much is possible with these three outputs and the Shape control alone, but Lorelei goes further to offer linear and exponential FM inputs, as well as a cross‑modulation/sync input for some highly inventive and excellent‑sounding voices.
Waveform Magazine (issue #7 - read the full review here) said
You can get some really great sounds out of Lorelei and the feature set and overall quality of this module really outpaces the price of it.
