“‘Acrylic Interval’ is rhythmically the most intriguing piece on Polyarrythmia. It’s based on a session I did with NuPG [the New Pulsar Generator], a software synthesizer invented by Marcin Pietruszewski. I chopped up the most interesting moments and added other sounds, mostly made with Reaktor and Razor, a software created by Erik Wiegand a.k.a Errorsmith, plus tools from Dietrich Pank and Mike Daliot. These are the software I use for almost everything. I wanted to do a rhythmic stream, something that drummers could play along with. It doesn’t have a strict metronomic clock, but it implies one. It starts with this staccato kind of thing, and then it goes off beat and fully disperses, then builds up again. It even has a kind of implicit grand finale.” — Jan St. Werner
