Ratings and reviews

Quick, easy, and simple! Great for quickly getting those exact Ms settings for older FX units that pre-date MIDI sync (my Yamaha GEP-50, for example). No more fumbling with a calculator to determine every possible polyrhythm value to get your echoes on beat or syncopated perfectly. Exactly what I needed... Exactly what *every* old-school hardware-based producer needs!
