EXPERT SLEEPERS | Lorelei - VCO Voltage Controlled Oscillator

"Lorelei is a versatile oscillator by Expert Sleepers with quadrature sine outputs, waveshaping and sync/cross-modulation options.

From the manual:

Cross-modulation/sync: in a common-or-garden ramp-based analogue VCO, oscillator sync works by resetting the ramp integrator based on the frequency of the syncing signal. Lorelei works quite diferently, though similar efects can be obtained. In Lorelei, the sync input essentially prevents the oscillator from oscillating when the input is above a certain voltage (around 3.3V), but this is not an on-of thing – the efect gradually applies as the voltage increases. The upshot of this is that smooth waveforms (e.g. sine or triangle) for the syncing input produce a diferent efect to, say, square or pulse waveforms. Also, when using a pulse wave as the sync input, the pulsewidth of the signal also afects the result quite drastically."
