music@nathanielschool.comRefund policy
30 days, no questions. A fast refund protects trust better than a long argument.
Abuse and rights
GrabIt rights or acceptable-use reports should include the media title, claim and relevant links.
Sangam
Every source on one clock. A microphone you can leave on.
- Live app playback can stay on Core Audio's direct path while Sangam aligns the copied mix. Version 1.2.2 measured a 32 ms Sangam path on the tested studio setup; total delay depends on sources, hardware and the receiving app. Cameras may need a measured A/V correction. For self-monitoring use your interface's direct monitor.
Shruti
Per-app volume, EQ and output control for Mac.
Relay
Control your Mac from your iPhone.
- Mac 0.2.2 build 45 is the downloadable testing companion; the Relay iPhone app is required and public iPhone delivery is not available yet. No checkout is open.
- Older Mac copies require one initial download before signed automatic update checks work. Installation is confirmed by the user.
- Physical gestures, clean-user/device recovery, second-Mac acceptance and final privacy review remain open; Watch testing is deferred.
Prism
One player for media, scores and MIDI.
- Apple silicon and macOS 15 or later only; tested on one Mac so far.
- Private or unavailable Instagram posts show a clear message with an Open original button; DRM-protected media does not play.
- Instagram native playback and YouTube playlists need GrabIt installed.
- Copies without an updater need one initial download. Current builds discover signed compatible updates; installation and relaunch require your choice.
GrabIt
Capture a lesson. Keep the useful moment.
- GrabIt 1.23.1 build 41 targets macOS 13 or later, with durable incremental indexing and user-confirmed signed updates; a found update shows an Update available button in the main window. Studio runtime acceptance is on macOS 15.6.1; each installation requires an explicit choice.
- Paid checkout and paid activation are closed. Paddle's published acceptable-use policy lists streaming downloaders among prohibited categories; product eligibility and the complete purchase, recovery and refund journey are not cleared.
- The matching FFmpeg 9.0.2/x264/LAME source archives, pinned build recipe and provenance accompany this release. This does not provide matching source for older provider-built FFmpeg releases.
- Windows 10/11 and Linux ports are unfinished; there are no installable packages for them. Physical Intel/macOS 13, clean second-Mac and restricted-source acceptance remain open team checks.
Kosh
Know every drive: what's on it, how healthy it is, what it's good for.
- Apple silicon and macOS 14 or later only; tested on one Mac so far.
- Many USB enclosures do not pass the drive's own health data through; Kosh then relies on macOS error counts and its read check, and says so.
- Copies before 1.0.3 were team-only and need one download of the current version to join the public update channel.
Groove Metronome
A metronome that teaches groove, on the Mac.
- Copies older than 1.3.1 have no in-app updater and need one download; after that, signed updates arrive inside the app and install only after the user's choice.
- Runtime verified on Apple silicon; the Intel slice has not been run on a physical Intel Mac.
Chorale
Live vocal harmonies, steered by your voice or the chords you play.
- Shifted voice artifacts remain possible on breaths, very low notes and extreme intervals; the dry path is immediate inside the processor.
- Tested on one studio Mac; the Intel version has not been run on a physical Intel Mac.
- Copies before 1.14.2 used a private team update check; team copies of 1.14.1 receive 1.14.2 through it, older copies need this download once.
Riyaz
From a pencil sketch to a part you can rehearse, on the Mac.
- Copies older than 1.6.0 were internal and have no updater; 1.6.0 is the first public build and updates itself from here on.
- Runtime verified on Apple silicon; the Intel slice has not been run on a physical Intel Mac.
