Crossfade Loop Synth is actually two plug-ins: Crossfade Loop Synth and Crossfade Loop Synth Effect. The effect version takes the power of Crossfade Loop Synth and turns it into a live sampler, a looper and a very unusual and powerful delay effect.

Crossfade Loop Synth
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.

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 extremely 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/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 note polyphonic, and all parameters can be controlled by MIDI controllers.

Crossfade Loop Synth Effect
Crossfade Loop Synth Effect is the same as Crossfade Loop Synth except you can record live audio to use as the sample, rather than just loading it from disk.

You can record continuously, even while playing back. This allows you to use the plugin as an extremely unusual and creative delay effect. For example you can have the delays played back at double the pitch/speed you played them. Or at double the pitch and backwards. Or as a chord. Or repeat the first beat of every bar... the possibilities are legion.

You can save the recorded sample to disk as an AIFF file for later use.
