Satyr is a massive Virtual Analog synth with comprehensive oscillator waveshaping and modulation methods.
It is inspired by the monster modular synths of days gone by and even though it is hardwired there are plenty of different modulation possibilities.
There are two oscillators with variable waves, additional sub osc and noise generator, ring modulation, FM, amplitude modulation and sync, three ADSR time/level envelopes (2 assignable) with delays and manual triggering, two variable lfos with sample & hold and two filters.
There is an internal clock for BPM synced Lfos and sixteen different modulation destinations. There are two filters, one 4-pole lowpass and one 2-pole multimode and they can be in parallel or serial mode, among others. So as you can see there is pretty much going on inside Satyr.
It sounds best when you set your VST host's sample rate to 96 kHz.
