The Qu-bit Prism is an effects module. It's an effects unit capable of high-fidelity to low-fidelity delay, beat repeat, looping, and comb filtering, among other things. Beat repeat is probably a pretty popular effect. It also has a stereo filter, so it can do a lot for its size, making it very useful. It's a module that can be used in very interesting ways, so if you're looking for one, please consider it. Thank you very much.
