About
A calm, clear tuner for every instrument: a big note name, a needle that glides instead of shaking, and a strobe when you want the last fraction of a cent.
TUNE ANYTHING
• Chromatic: play a note and see the nearest one, how many cents off, and which way to turn
• From a 5-string bass's low B (31 Hz) up to 4 kHz
• Steady tones within ±0.5 cent, bowed strings with vibrato within ±2 cent; the readout shows 0.1 cent
• Needle or strobe: the bands run left when low, right when high, and stand still in tune
• Hold keeps the steady part of a short note on screen, after the attack
• Stage mode: the note and the needle as big as the screen
THREE TUNING SYSTEMS
• Western: A4 from 415 to 466 Hz, with 440, 442 and 432 one tap away
• Thai: seven equal steps from the Fine Arts Department table, La = 417.2 Hz, names like "Sol 5" (or "ซอล 5" in Thai), and an option for textbooks that name the notes one step apart
• Custom: your band's own seven notes, made from a typed La, learned by playing them, or moved one by one in cents
MY INSTRUMENTS
• Save an instrument with its own notes: strings named your way, picked from the scale, typed in Hz or played in
• Auto finds the string you are playing; tap a string to lock it when you tune far, like Drop B
• Start from guitar, 4-string bass, ukulele, violin, saw duang or saw u
• Send an instrument as a file (AirDrop, Messages, Files): it opens with every value the same
AUv3 FOR YOUR MUSIC APPS
• Put STPZTUNE on a track in AUM, GarageBand, Loopy Pro, Logic Pro or Ableton Live (Mac): the sound passes through unchanged, with no latency
• Its settings and instrument are saved with your song
• A small plug-in window keeps the note and the needle readable
