# Illthy Toonzthe strobe tuner that refuses to twitch · free

Free VST3 zero 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.

## Controls

Control | What it does
--- | ---
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, 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.
