MIDI Tape Recorder2.0.2 - App Store

MIDI Tape Recorder takes a radically different approach to MIDI recording. Now in version 2.0, it runs both as an Audio Unit v3 plugin inside your favorite host and as a standalone app on iPhone, iPad, and Mac.

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 their editing features. These changes impact the playback of your performance as MIDI messages get reordered and delayed, altering 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.

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

The controls are purposefully simple and intuitive, like a traditional four-track tape recorder, making it fun to record, play back, and loop your MIDI performance. Even with non-MPE MIDI, it keeps you in the flow and creative, without being interrupted by the technical nature of most DAWs.

New in the standalone app: run MIDI Tape Recorder on its own, with CoreMIDI input and output to route your performance to any of your MIDI apps, synths, and hardware. Sessions are autosaved and can be saved, opened, and shared as documents. Recording keeps running in the background and with the screen locked, so you never lose a take.

MIDI Tape Recorder makes no sound on its own: as a plugin it records inside your host; as a standalone app it routes MIDI to your instruments.

Version History • Moved the crop marker flags to the bottom so two markers on the same position can be told apart.
• Improved cropping to keep the punch in and out markers, adapting them to the cropped take.
• Raised the MIDI buffer sizes so dense playing and MPE expression are not dropped.
• Fixed the first recorded event of a take landing slightly early when the recording starts the transport.
• Fixed other armed tracks missing the message that starts the transport when several tracks record at once.
• Fixed stopping a loop recording partway through a silent pass erasing the start of the loop.
• Fixed MIDI arriving right after Record is engaged from the host being dropped until the tracks were armed.
• Fixed recording over existing content erasing the recorded range when nothing was played.
• Fixed continuous loop recording losing what was played after a silent cycle.
• Fixed the track display blanking while a recording pass that played nothing was running.
• Fixed a loop recording pass inside a punch in and out region only being added when the playhead returned to the punch-in point.
• Fixed clearing a track while it was recording leaving behind an undo step that did nothing.
• Fixed a recording that captured nothing creating an undo step that did nothing.
• Fixed a recording never finishing when the playhead never reached the punch in and out region.
• Fixed undoing a take also reverting a MIDI file imported into that track while it was recording.
• Fixed cropping while recording leaving the running take behind in the uncropped timeline.
• Fixed crop and punch markers being impossible to grab where another marker or range covers them. 2.0.2 Sep 20 Fixed recordings running at double speed when not following a host transport. 2.0.1 Sep 5 • New: MIDI Tape Recorder as a standalone app. No host required: record, overdub, and play back MIDI right on your iPhone, iPad, or Mac, with CoreMIDI input and output routing to your other apps and hardware. Recording keeps running in the background and with the screen locked.
• Sessions and documents. Your work is autosaved, and you can save, open, and share .mtrec session files.
• New: continuous loop record. An opt-in option that keeps the loop rolling and re-records over your take on each pass instead of stopping at the end, refine a part without ever breaking your flow.
• Hardened MIDI file import: malformed .mid files can no longer cause out-of-bounds reads or event desync.
• Importing an empty (note-less) track now correctly clears the destination track.
• Fixed loop record acting on stale state after an undo or import.
• Fixed MIDI capture pausing when the screen locks.
• iOS 26 fixes: the About-window links (website, rating, donate) open again, and various stability improvements. 2.0.0 Aug 29 Minor improvements. 1.0.8 07/12/2023 Minor improvements. 1.0.7 01/25/2023 Fixes to message sample offset on playback. 1.0.6 04/13/2022 Minor fix to MIDI file export. 1.0.5 01/30/2022 * Added setting to allow disabling auto rewind after record.
* Added setting to only start playing at the next host beat, even when not following the host transport. This is useful when using MTR as a clip launcher.
* Record arm is now preserved in the AUv3 saved state.
* Added Music Effect AUv3 alongside the MIDI Processor AUv3, note that the majority of hosts don't support MIDI output from Music Effect AUv3s but recording is possible.
* Added Instrument AUv3 alongside the MIDI Processor AUv3, note that while this will allow recording any MIDI in a host's track, it usually prevents having another instrument on the same track so it might be impossible to hear sound.
* Workaround for Logic Pro X issue that prevented MIDI Tape Recording from working. MTR now fully works on macOS Intel and Apple Silicon in Logic Pro X.
* Workaround for Logic Pro X sending an out of range beat position at the start of transport, resulting into the MTR recording duration being too long until the recording catches up.
* MIDI passthrough LED indicator in now disabled when the host doesn't support AUv3 MIDI output.
* Reworked settings UI dialog.
* Fixed auto-trim recording when overdub duration is longer than original recording.
* Fixed UI max duration calculation when auto-trim changes length.
* Fixes to recording with host transport from a blank session.
* Fix that properly clears recording state when invalidating or clearing a recording.
* Fix for MIDI file export sometimes containing an invalid end of track marker. 1.0.4 01/17/2022 * Improved beat positioning of MIDI events when recorded with moving host transport, this ensures exact alignment with the host's musical time.
* Fixed recording from other MIDI plugins (like Fugue Machine) with host transport sometimes creating a very long recording duration.
* Added setting to disable following the host transport (useful for background recording).
* Added AUv3 parameters to clear all and clear specific tracks with confirmation (double-activate the parameter within 2 seconds).
* Fixed clear all not always clearing the duration of the session. 1.0.3 01/08/2022 * MIDI file export now uses the .mid file extension instead of .midi.
* Lowered iOS target version to 12.3. 1.0.2 12/30/2021 Fix for track clear sometimes leaving preview data behind and requiring a second use. 1.0.1 12/28/2021 1.0.0 12/25/2021
