MusicTech review about FRMS - Granular Synthesizer

Review: Imaginando FRMS

By the time we reached the 20th century and the advent of the electronic age, sound creation had been elevated into a science in its own right. By now, we had a plethora of new techniques with which to craft new sounds and instruments. The invention of computing and digital-signal processing would truly revolutionise music and sound design once again, unshackling them from the expense, bulk and complexities of physical circuitry (or indeed rock formations), and thereby allowing synth designers to combine disparate techniques in any way they could imagine – all of which brings us neatly to FRMS.

Hearing is believing

Listen to our audio examples to discover just a small selection of FRMS - Granular Synthesizer's infinite possibilities

After discovering VS, I tried FRMS and found it ideal for blending live acoustic instruments with electronics. As a contemporary composer, I value its creative potential—granular, FM, and subtractive synthesis—to generate evolving textures. The preset libraries are inspiring, and the ability to granulate any sound source, even live input, is incredibly powerful.
