Bastl Instruments Kastle 2: Open-Source Evolves the Pocket Synth

Bastl Instruments takes their cult Kastle 2 semi-modular synth deeper into community territory, spotlighting the v1.7 firmware update and a host of wild third-party firmwares. The video gives an in-depth look at new features like swing, humanize, and assignable modulation, while exploring the open-source ecosystem that’s grown around this pint-sized sonic laboratory. If you’ve ever wondered how far a pocketable synth can stretch when the code is open, Bastl’s latest show-and-tell is a goldmine of patch ideas and community-driven weirdness.

Bastl Instruments & Oliver Torr: Building Sonic Worlds, One Patch at a Time

Step into the world of Oliver Torr, where sound design blurs into speculative fiction and every patch cable is a portal to a new reality. In this Bastl Instruments feature, Oliver unpacks his approach to world-building through sound, using the Citadel and Kastle 2 Wave Bard as tools for controlled chaos and creative exploration. The video is less a product demo and more a philosophical jam session, revealing how personal sample packs, environmental recordings, and a dash of unpredictability can transform modular improvisation. Bastl’s open, community-driven ethos is the perfect backdrop for this journey—reminding us that sometimes, the best sounds

The Unperson’s OP-1 vs Modular FX: Turning a Cult Classic into a Sonic Street Weapon

The Unperson is back in the rave bunker, this time dragging the Teenage Engineering OP-1 into a modular FX cage match. Love it or loathe it, the OP-1 is still a cult favourite, but let’s be honest: it’s got some gaping holes, especially if you crave stereo and proper effects. Instead of moaning, The Unperson wires up a Eurorack FX rack and shows how to make this plastic legend punch way above its weight. If you’re into glitchy textures, filthy delays and unpredictable radio sampling, this one’s for you. Don’t expect hand-holding—expect inspiration, chaos, and a few sharp elbows.
