Sonicbits shared this video demo for Silk, a virtual analog synthesizer plugin dedicated to a single waveform: the sawtooth.

Silk has two sawtooth oscillators, which each generate a unison sound of 7 combined voices. These parts in this “multisaw” can be detuned and blended in, leading to a very ‘rich airy and bright sound’, with lots of harmonics. An additional noise oscillator can add some dirt.

These oscillators build the sonic heart of Silk. This sound is then shaped by the filter. In addition to the classic low, high and bandpass filters often used in subtractive synthesis, Silk has a formant filter, which produces voice-like sounds.
