White Noise Audio has released Memory - a free buffer repeat / phrase sampler VST effect for Windows created specifically with live performance in mind.
Memory allows you to loop incoming audio (in forward and reverse), change the loop size on the fly, and filter it, all while staying locked to the tempo. Memory is also their first plugin to offer native support for the P5 Data Glove which should excite people looking for creative/alternative control methods.
Memory is released for free as a thanks to the online music community.
