Back and Forth was born of 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.
Based on Lorenzo’s experience on the art of turntablism and Matteo’s ability to produce distinctive sound effect libraries, this collection is now an easy way to add real scratch and turntable performances to your musical and audiovisual projects, and finally make them sounds better then ever before.
The unsurpassed sound of the needle in the groove and the cuts of the crossfader generate an unmistakable music quality and uniqueness.
The library follow the naming structure provided by UCS (Universal Category System), a public domain initiative supported by sound librarians, vendors, and users from around the globe.



“Back and Forth” is the only construction kit that allows you to create an entire song using the various samples within it. Hearing is believing:

“When I discussed with Matteo about how to carry out this project, I immediately thought of condensing the entire panorama of the world of turntablism and scratch, with its sounds and technicalities, inside this collection. The result is out of the ordinary because it encompasses almost two years of studio recordings including percussive samples, the great scratch classics, musical cuts and manipulations of vinyls and needles.” – Lorenzo di Tria

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.

Back and Forth – 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, from the most old school Breakbeat, to the freshest Trap Vibe. Now you can easily add some real-sounding scratch sfx to your musical productions with a Max for Live device that simulates a realistic freestyle by a DJ. All audio samples are recorded with pristine A/D conversion to get the maximum sound quality and preserve all the nuances of the different manipulations and techniques.


But wait, there’s more: THE QnA LOOPER – VOL.1 is included in the package and it’s free! It’s a new way of thinking the scratch looper. Now you can easily improve your dj skills using just this Max/MSP standalone application (for Mac and PC) and practice on 18 different beats with an automated scratch engine! With 900 sample-based answers, the QnA Looper makes easier and smarter your training sessions.
