About

Know the note. Get the numbers. Back to the beat. Ordinary tuners are built for long, sustained notes. Play a one-shot through one and the needle jumps around during the attack, then goes blank before you can read it. Latch Tuner is built for how producers actually work: it skips the attack, measures the body of the sound, and holds the answer on screen after the sample has ended. How it works. You chopped a bass note from an old record and it's fighting your track. Insert Latch Tuner on the channel, trigger the pad once, and it reads: E3 −26.5 ¢ · 324.6 Hz · MIDI 64 Set TARGET to the note you actually want — say C3 — and it does the conversion for you: SEMI −4 · FINE +27 Those are the two numbers your sampler's pitch controls take. Type them in, retrigger, done. No looping the sample into a phone tuner, no guessing against a piano. Two modes. • LATCH — for one-shots, chops, plucks, vocal stabs and 808s. Transient-aware capture holds the reading until you clear it. Capture history keeps your last few results on screen, so you can work through a whole kit without writing anything down. • LIVE — stop switching apps to tune. A straightforward in-line tuner for guitar, synth and voice, docked in a corner of your session. It tells you when it isn't sure. A gliding 808 or a reading that wobbles between octaves is flagged instead of shown as a plain answer. Built for single notes: a chord reads as one of its notes, usually the root. Noise and washed-out chops report no clear pitch, because there isn't one. Tap PLAY to hear a reference tone against the sample and decide with your ears — below ~80 Hz the tone adds an octave-up partial so you can hear it on a device speaker. Speaks sampler. Note name, cents, frequency and MIDI note number, plus the SEMI/FINE correction to your chosen target. Samplers disagree about octave numbers, so the readout shows its convention next to every answer — and a C3/C4 toggle matches it to yours. It can't silently put you an octave off. Adjustable reference pitch (440, 432, 442…). Runs where you work. An AUv3 audio effect — use it in AUM, Koala, GarageBand, or any other AUv3 host. Plus a standalone app that listens through the mic. Audio passes through untouched. One-time purchase. No subscription, no ads, no account. Everything is analyzed on-device; nothing is recorded or uploaded.

What's New in Latch Tuner

1.1

October 27, 2026

- IMPROVED: HELD ? now appears only when the reading itself is in doubt: the pitch moved during the capture, the note wobbled between octaves, or there was too little clean signal. Before, a quiet or noisy microphone signal flagged most readings with a question mark, including correct ones; expect fewer of them through the mic. - IMPROVED: In a room with background noise, a measurement now ends when the note fades into the room instead of running on into its fading tail. - FIX: Some notes could read an octave or more too low with no warning. The open D string on a guitar read D2 instead of D3, usually with no warning; it now reads D3 in our recordings. A weak note over room hum could read several octaves down (an A3 shown as B0); that now happens much less often. - FIX: Clean tones between about C#3 and E3 (roughly 140–159 Hz), such as sine or synth notes, could read about two semitones sharp with no warning. They now read correctly.
