Ableton/Live/UG/31 Instrument Reference/08 Meld/09 Filters
- Filter A and Filter B have their own on switches, a Frequency knob, 17 types and two macros per type, most often Q (emphasis at cutoff) and Drive (input saturation).
- Types:
- SVF 12dB / 24dB — state variable; L-B-H-N morphs low-pass, band-pass, high-pass and notch.
- MS2 — low- and high-pass from a Sallen-Key design in a well-known Japanese semi-modular mono synth, with soft clipping on resonance.
- OSR — band-pass from a rare British mono synth, resonance limited by a hard-clipping diode.
- LP Crunch 12dB — feeds its own distortion back in.
- LP Switched Res — resistors replaced by fast switches for downsampling artifacts; Lofi high is crushed, low is smoother.
- Filther — low-pass with hard diode clipping in and soft saturation out.
- Eq Peak / Eq Notch — Boost or Cut around the cutoff.
- Phaser — six-stage with Feedback and notch Spread.
- Redux — resampler and bitcrusher; Crush sets bit depth, Lofi mixes filtered downsampled signal with raw artifacts.
- Vowel — formant filter; Morph moves between vowels.
- Comb + / Comb - — feedforward and feedback combs with Feedback and Damp.
- Plate Resonator — 32 modes of a rectangular plate; size, resonance and ratio. Scale-aware.
- Membrane Resonator — 32 modes of a round membrane; size, resonance and high-frequency damping. Scale-aware.
