A true strobe tuner: the scrolling LCD is the meter, the way a strobe should be. No needle. The bands drift when you’re off and crawl to a dead stop as you land it. Fast and reliable on every string, standard through 8-string and drop tunings.
Zero latency, pure pass-through. Your signal is untouched. Same tuner brain that lives in NoAMP.
New in v0.6.2: the name in the brand band is set in the line’s new open-licensed typeface (and the Ill Sea logo beside it wears the same bevel), and the zip now lists the open-source software inside (THIRD-PARTY-NOTICES.txt).
New in v0.6.0: the line’s new look: the strobe in a glass well, ON / MUTE / STEADY in the card’s title row, machined knobs. The tuner itself is unchanged.

1. Play one string and let it ring.
2. Bars scroll one way = sharp, the other = flat. Finer bands up top read finer error.
3. Tune until the bars stand still and the hub glows — that’s locked. Done.
Numeric cents/Hz, the A4 (415–466), the Response feel knob and Transpose (capos) are all right there. Full reference on the Toonz manual page.
