The problem

Hitsounding in osu! means juggling sample sets, additions, volumes and custom indices across hundreds of timing lines. The usual workaround is a dummy 18-key mania diff in Mapping Tools, which says mappers want lanes; the workflow just isn't there.

What it does

A channel-rack of lanes, each bound to a sample set, addition, index and volume, over a waveform with BPM-snapped grid and ghost notes from your other diffs. Exports a clean [Hitsounds] diff and can copy hitsounds into the mapset without touching slider velocity. Runs entirely client-side.

How it works

Give it a map link, ID or .osz. It pulls every other map of that song from the Hinamizawa mirror and compares rhythm timing, object positions and slider shapes, including flipped, rotated and shifted copies, then points at the exact stretches that match, on a playfield overlay you can scrub through.

Log in with your osu! account, summon beatmaps as collectible cards, keep a collection. Made for fun, a friend asked for it.

The problem

With mechanical switches in this board, hard taps type the letter twice. The debounce slider in MonsGeek's app does nothing, there's no fixed firmware, and their web driver barely works on Linux.

What it does

Reports a press the moment the contact closes, but only reports the release after it has stayed open for 8 ms. Stock did 13 to 165 doubles per test run, this does 0 in 121 hard taps. It also does typing over USB and 2.4G, the Fn layer, per-key RGB and settings saved on the board, and comes with FUN60 Studio, a web driver to remap and tune it. Sleep and Bluetooth aren't done yet.
