Demo of Stalys Plugin. Requires v1.4.2 or above.
A simpler patch here: The only sound source here is one sine osc, FM-ed AM-ed and hard-synced by two other ones. Side is fed back to the reverb as well.
The sound is processed asymetrically to hard and soft clip, before running to a reverb.
The melody comes from 6 free-running LFOs outputs’ max value.
The dynamics are handled by those same LFOs, min values, plus a negative offset and a slewed gate when the melody is not too high.
Beside the feedback, not much mid-side processing, except for some LFO inputs to the wide parameters of both in and out.
