SSL Module8: Modulation FX Rack Plug-in by Solid State Logic

Each of the six modulation modules is driven by an LFO. The Phaser module sweeps the input with all-pass filtering, creating peaks and troughs in the frequency spectrum that move over time. The Flanger mixes the signal with a modulated delayed copy of itself, producing comb-filtering that shifts as the delay changes.

Chorus duplicates the input and modulates the pitch of the copies to add shimmer and width, similar to several instruments playing in unison. Tremolo modulates amplitude for rhythmic volume changes, from subtle fluctuations to deep pulsing. Vibrato modulates pitch up and down for a quivering, animated quality, and the Panner automates stereo position to move sound from side to side.

Modules can be re-ordered by drag and drop, so you can change the sequence of the rack without rebuilding the chain. A global mix control and a global width control apply across the rack, letting you blend the processed signal with the dry input and adjust the stereo spread.

Modulation is shaped with five LFO waveforms, with both sync and manual LFO options. The Lo-Fi and Space modules serve as creative FX returns for degrading or spatializing the sound alongside the modulation modules.
