Very odd module, strangely designed, but awefully cool and very useful. You can basically sample anything into it and turn it into a wavetable. It tracks fairly well too, I think I've read over 4 octaves or so. Scanning the wavetables while sequencing is just a blast. Sample some field recordings into this thing, and I swear it's going to produce oscillator sounds that you've never heard your modular produce before. It's lo-fi, of course, but terribly versatile, and it sounds good in my ears. Excellent module. Well worth the little money it costs on the used market.
