Matt Mower has introduced Reichatron – a free sample playing instrument for Reaktor, inspired by the early phase-shifting tape loop experiments of Steve Reich.
Reichatron allows you to mix together the phase-shifted blending of two samples and then modulate that mixture using a block of six effects that can be independently controlled. Reichatron also offers stochastic control of the effects block and sample selection. You can take as much, or as little, control over how the sound evolves over time as you like.
