I associate the sqsl account on YouTube as a demo zone for the always intriguing app output of seqsual.com. The seqsual product line consists of fascinating, design-forward, task-specific iPad apps for music-making. These include controllers, sequencers, and sample players. But this video is something different. Unless I’ve missed a detail, none of the synthesizer modules employed here — all hardware — are related to the seqsual catalog. (I do recognize this gear from another a video, one for the seqsual app Canvas, which interacts with physical modular synths, but that isn’t in use here.) This apparatus is a whole other realm, drawn from other music instrument manufacturers, and what’s happening is a delirious frenzy of signal swapping, all glitched and stuttered — a surveillance nocturne, as it were. Maybe it’s a hint at an upcoming seqsual release. The gestural reuse of existing sonic material certainly taps into seqsual’s overall activity. Great stuff, in any case. (I believe the name of the software developer, who I think is based in Finland, is Michal Macura, who also goes by Miso.)
