OR—1 is an artful, generative MIDI sequencer maker. It’s free for iPad as an AUv3, with a desktop macOS version available for €19.99. And it’s an exquisite experience feeding these into synths.

Tekno from Baby Audio was easily one of my favorite plug-ins of last year — it’s a rich, “bend”-able, brutal box with the feeling of hardware drum synthesis.
