# Illthy Toonzthe strobe tuner that refuses to twitch · free

Free VST3 zero latency

A smooth strobe tuner with a needle on a spring: it knows the difference between YOU turning a peg (it stiffens and tracks live) and a string just ringing (it relaxes and sits dead-still, with a magnetic zero inside ±1.5 cents). Fast on every string — 7-string and drop tunings included. Pure pass-through: your signal is untouched, zero latency.

## Reading it

1. Play one string, moderately — let it ring.
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 there — the needle centres and locks.

## 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. Lower = twitchier needle, higher = calmer needle + steadier Hz readout. It trims the spring, not a lag filter — the needle never crawls.
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

Pitch | MPM/NSDF with YIN cross-guards; adaptive windows (fast 2048-sample default, 3072 mid window below ~55 Hz) at an 11.025 kHz analysis rate
Cents | heterodyne strobe drift, hop-averaged per-string so every string lands at the same noise floor
Needle | critically-damped spring + motion detector (peg-turn tracking) + magnetic zero
Guards | sympathetic sub-octave rejection — drop-tuned octave pairs don't drag the read down an octave
Range | ~27 Hz (drop A on an 8-string) to 1.4 kHz

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