Synths node
Analog
A polyphonic virtual-analog voice: two oscillators (the first a unison stack), a sub oscillator, noise, a drive stage, a nonlinear filter (Moog ladder, MS-20, diode ladder or SVF) and an amplitude envelope across up to 8 voices. Narrow-band oscillators and a 4x drive and filter keep aliasing under -80 dB, and default patches are in tune.
What it does
Analog is a synth: it turns notes into sound. It takes notes in and gives audio out.
Try it
Stack three detuned voices, open the MS-20 filter and sweep the cutoff with an envelope.
