01Overview

ResDelay pairs two production techniques, envelope filtering and stereo delay, in one unit. The filter opens and closes based on the level of the incoming signal, so drums, bass, plucks and full mixes can drive resonant sweeps. The delay section adds rhythmic repeats with independent left and right times, giving producers a single tool for groove, movement and tension.

Audio-Reactive Filtering and Sweeps

The filter follows the level of the incoming audio, opening and closing as the signal moves. You shape its behavior with envelope threshold and decay controls, along with the frequency range set by hi and lo-cut sliders, resonance and cutoff steepness.

This makes it practical for squelchy, analogue-sounding bass and for adding motion to synth stabs and arpeggios. Used on a group of plucks, it can also help glue the sounds together.

Stereo Delay Patterns and Timing

The delay gives full stereo control, with independent time settings for the left and right channels. Ping-pong and stereo modes, feedback, hi and lo-cut filters and a dry/wet mix let you fine-tune the repeats.

Straight, dotted and triplet timing options make it easy to lock the delay to the groove of a drum pattern or to build rhythmic movement across a track.
