Back and Forth was born from an idea of Matteo Milani and Lorenzo di Tria (aka Dj Mate/Signal Generator), thinking on how to build an intuitive and great sounding music tool for contemporary producers and sound designers. Back and Forth differs from any other scratch library on the galaxy for its 400 samples recorded entirely in the studio only with real vinyls, plus a unique Ableton Live Instrument (.amxd): the Scratch Machine. It's a magical sample-based scratch improvisator that combines many different scratch combos with criteria. With the ability to choose six different classic samples (THA, FRESH, TWAI, AYE, YE, YO), the Scratch Machine adds a timeless and authentic turntablist to any type of production. But wait, there’s more: THE QnA LOOPER - VOL.1! Now you can easily improve your dj skills using just this Max/MSP standalone application and practice on 18 different beats with an automated scratch engine.
