MIDI Tape Recorder, precise capture, now standalone for macOS, iOS

Geert Bevin’s terrific MIDI Tape Recorder precisely captures MIDI performances, including MPE, verbatim — not the slightest variation in sound. v2.0 adds a host of new features, plus a standalone version alongside the existing AUv3 plug-in. It’s low-level, direct CoreMIDI capture of what you played, exactly as you played it, with every expression intact. And it’s and open source.

Organismi OR—1, free for iPad: breathing, stochastic pattern generator

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.

Baby Audio’s Tekno drum machine gets a sequencer and iOS AUv3 version

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. And now it gets a step sequencer, plus a ton of tweaks you might have missed in the first release. And one more thing: iOS users, there’s a mobile version with AUv3 version.
