# Illthy Toonzthe strobe tuner that refuses to twitch · free

FreeVST3zero latency

A true strobe tuner: the scrolling LCD is the meter, the way a strobe should be. There is no needle. The bands drift one way when you're sharp, the other when you're flat, and the closer you get the slower they crawl, all the way to a dead stop. Fast and reliable on every string, standard through 8-string and drop tunings. Pure pass-through: your signal is untouched, zero latency.

## Reading it

1. Play one string, moderately, let it ring. The big note name tells you where you are.
2. The bands scroll one way when you're sharp (lime drift), the other when flat (purple). Finer bands at the top read finer error.
3. Tune toward the bars slowing down. When they stand still and the hub glows, you're locked. Done.

New in v0.5.2, the strobe stopped twitching. The bar colour used to flip the instant you crossed from flat to sharp, so a string sitting right at pitch flashed between the two constantly. The colour now eases between them and settles on the in-tune lime, scaled so a given error looks the same on a low string as a high one. Want it to hold absolutely still? Turn on STEADY. (Thanks to the player who wrote in about this.)

## Controls

Control | What it does
--- | ---
ON | The tuner itself (v0.5). Off parks the analyzer completely, display dark, audio still passes.
MUTE | Silences the output while you tune (v0.5), the tuner still hears you. Classic pedal move.
STEADY | Holds ONE colour (v0.5.2). The bars still scroll to show sharp or flat, they just stop changing colour, so the tuner can sit on screen while you play without pulling your eye. Off by default.
Reference A4 | 415–466 Hz calibration (440 default; 432 for the cult, 415 for baroque friends).
Response | The FEEL knob, 100–1000 ms, on the numeric cents/Hz readout. Lower = twitchier numbers, higher = calmer + steadier. The strobe itself always tracks live.
Input Gate | Below this level the display HOLDs. Default Off; raise it on noisy rigs.
Transpose | ±12 semitones for capos and transposing instruments.
Labels | Sharps or flats.

## Specs, tersely

Note | MPM/NSDF with a YIN octave cross-guard + a phantom-fundamental veto (v0.5: on octave-pair tunings, a string ringing an octave below the one you're tuning can no longer steal the lock), one 4096-sample window at an 11.025 kHz analysis rate, full-range so the note is right from the bottom string up
Strobe | quadrature heterodyne against the locked note, the drift rate scrolls the LCD and reads out as cents/Hz
Display | strobe-first: the LCD is the meter, no needle. The note, the numeric cents/Hz and every control are on show at once
Range | ~23 Hz (low F#/E on an 8-string) to 1.5 kHz

In NoAMP, the built-in TUNER module is the same brain, and it mutes only your live signal; a playing loop keeps sounding.
