MIDI Tape Recorder is an open source Audio Unit v3 plugin with a radically different approach towards MIDI recording.

MIDI messages are recorded and played back with the same accuracy and precision as audio recordings. Most modern DAWs, even at their highest resolution, still change the timing of MIDI messages to accommodate for their editing features. These changes impact the playback of your performance as MIDI messages get reordered and delayed, causing changes in how they influence sound, sometimes in very significant ways.

MIDI Tape Recorder records your performance exactly as you play it, just like an audio recorder, accurately reproducing every nuance of your performance.

MIDI Tape Recorder purposefully has no MIDI note editing, no quantization, no individual CC tweaking, nothing that you wouldn't do with audio. Instead, very expressive and ultra-dense MIDI streams are perfectly stored and reproduced. MIDI Tape Recorder excels at capturing and playing back expressive performances with MPE controllers and MPE MIDI plugins.

The controls are purposefully simple and intuitive, similar to a traditional four-track audio recorder, making it fun to record, play back and loop your MIDI performance. Even when recording non-MPE MIDI, MIDI Tape Recorder makes it easy to stay in the flow and be creative without being interrupted by the technical nature of most DAWs.

MIDI Tape Recorder makes no sound on its own and requires an AUv3 host to function.

Captures the Human Performance

This is such an exciting plug-in that does exactly what I’ve been waiting for. It captures every nuance of my imperfect performance, and all the subtle human character of my unique movements. A performance recorder that doesn’t “correct” my input. I love being able to perform first, then try different sounds and instruments with that performance exactly how I played it. It’s a fresh and different approach to my work. I can’t believe it’s free! Please tip the developer for this wonderful piece of software.

My first app review ever…

This app is so outstanding and excellent and all the good things that the other reviewers have already mentioned. Thank you for making this app, and should you decide to start charging for it you won’t get any complaints from me. BUT there is just one thing that doesn’t seem to be working correctly for me, and that’s the midi import function. Pressing the import MIDI file button shows me a list of “Locations”, fine. I wish to import a MIDI file from AudioShare, so I press on that icon and nothing happens. I presume correct behavior would then show me a column with all the AudioShare folders displayed. Is that correct? Similarly nothing also happens when I press any of the other “Locations” shown. Other than this one bug, this app is quite a dream come true.

Excellent little midi recorder

Does exactly what it promises and is super handy. No problems in AUM or Drambo. Negative reviewers should read the documentation and perhaps study up a bit more on how to work with MIDI and AUv3 plugins in their preferred host app.

Also, if you get really bizarre recordings that sound like some invisible, recently used IAA midi source app hasn’t closed properly - restart your device. 🙃
