Yamaha reface CS virtuālais analogais sintezators

Analog Physical Modeling Engine with multiple synthesis and oscillator types
Each oscillator type has flexible LFO and ADSR routing plus unique Texture and Mod controls that work as follows:
Multi-saw
Texture, control adds sub-oscillator
Mod, layers multiple sawtooth waves
Pulse
Texture, changes pitch of 2nd square wave
Mod, change pulse width
Oscillator Sync
Texture, changes pitch and tone of OSC2
Mod, sets pitch change amount
Ring Modulation
Texture, changes pitch of OSC1
Mod, changes pitch of OSC2
Frequency Modulation
Texture, sets Modulation amount
Mod, changes pitch of the Modulator
