What's New in PolyrhythmLab

2.0.1

October 22, 2026

• Fixed: the AUv3 plugin now plays when the host transport plays (AUM, Cubasis, and others) — previously it only made sound with its Preview button. • Host Tempo now follows your session's tempo and locks the pattern to the host's beat grid. • Improved real-time stability of the plugin.

Does not work as AUv3. Stand alone only and saying it’s basic is being nice

Warning. This does not work in AUM or Cubasis. In both it just shows a euclidean circle,4 “instruments” , a sync button that does nothing, a preview button and bpm slider and a random button. Only way to make noise is to hit the preview button. You cannot change most of anything.
Everything else is stand alone only. The visuals are basic at best. I would have asked for a refund but I waited a day to try it, so refund timed out 😤

Response from developer

Thanks so much for the detailed feedback, and I'm really sorry the plugin didn't work for you in AUM and Cubasis — that was my mistake. It was only making sound while the host was recording or Preview was on, so pressing Play did nothing. Version 2.0.1 fixes it: it now plays along with the host transport and can follow your session's tempo. It's currently waiting for App Store approval, so it isn't available just yet, but it should be out very soon. I'd really appreciate the chance to make this right — please write to me at martoadler@gmail.com and let's sort it out. Thanks for your patience!
