The Freesound and Delay bundles are a collection of plugins that were developed while teaching music programming at UCSD and CalArts. Get all 9 plugins in one fell swoop.
The ++delay gives you classic delay effects, with a wide ranging filter section to help emulate vintage delays, an LFO time modulator with triangle, sine, ramp, square and random waveforms, as well as freeze mode, dual-head mode and feedback inversion. Both the delay time and the LFO modulator can be synced to multiples and divisions of the host clock.
