Grainfreeze is a basic granular synthesis effect plugin, designed to create the illusion of freezing incoming audio like the Reaktor "grainstates" instrument.
There are four different grains. When you press freeze, the audio goes into the four grains/buffers. There is an envelope to control the shape of the grain and to smooth the sound. You can set a different length for each grain and also delay the time at which the buffer is stored. You can also create a fade so that the frozen audio gradually appears. An LFO can control the pan for each grain. MIDI notes will also trigger the freeze.
