From Expert Sleepers:
Crossfade Loop Synth is 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. You can control how the sample is looped as it is played. An adjustable amount of crossfade can be applied to the loop endpoints to smooth the transitions. This makes it easy to produce glitch-free pad sounds. The loops can also be played backwards and alternately forwards and backwards (pendulum-style). Further sound processing can be applied in the form of overdrive or saturation, filtering, envelopes (for amplitude and filter), pulse-width modulation, oscillator sync, and LFOs (one each for filter, pitch, PWM, and sync). The synth is 32 notes polyphonic, and all parameters can be controlled by MIDI controllers.
