Expert Sleepers has updated Augustus Loop to version 1.6.5 and Crossfade Loop Synth to version 3.0.2, two plug-ins for Mac OSX.
Augustus Loop is an emulation of a tape-based delay effect, with some extra features to facilitate its use as a looping device.
Crossfade Loop Synth is at heart a simple sample playback synth plug-in. It plays samples in the classic sampler manner – by simply altering the playback speed according to the desired note. No fancy timestretching or pitchshifting is applied.
Both these plug-ins now respond properly to AudioUnitReset(), so in e.g. Logic the delay buffer will be cleared when song playback is started etc.
Augustus Loop (Mac OSX/AU UB) costs $29 USD and Crossfade Loop Synth (Mac OSX/AU/VST UB) is $49 USD (plus VAT if applicable).
