Nasko’s completely free N-IRIS is a spectrum disperser – why that’s cool

Nasko, the prolific and imaginative software developer, is back with a new one – and it’s completely free, running in Plug Data (Pd) on Mac, Windows, and Linux. It’s a convolution-based spectrum disperser. Say what? Well, you get a powerful, precise, fairly rare method for generating impulse responses for convolution tools, like Kilohearts Convolution (now on sale), the one just added to Serum 2, and more. Or just play it live, because that also sounds kind of awesome.

Three free spectral synths to try after the new Serum spectral oscillator

Spectral resynthesis is having a moment now that it’s one of the new oscillator types in the mighty Xfer Serum 2. If you’re looking for other ways to get your spectral resynthesis on – or you’re a Serum user who just can’t get enough – here are three free tools to sink your FFTs into.

bop: free, fast, friendly, fun music stuff for Pd, old CPUs and RasPi

It’s free, it’s fast, it’s fun, it’s bop for the free Pure Data Vanilla. It runs on old computers. It runs on Raspberry Pi. “You probably don’t have any use for bop,” its developer says humbly – but wait, with everything from text sequencing to reverbs to esoteric musical notation, this looks great!
