EditMIDI Keeps the Cleanup Bench in Your Browser

Why it surfaced

EditMIDI is unusually explicit about what its focused tools do: transpose leaves drum channel 10 alone by default, quantization avoids zero-length notes, and edits remain local unless you choose Creator Cloud. It also preserves non-note events around the edit, making this feel more like a careful repair bench than a generic sketch composer.

A local-first MIDI editor with a piano roll, playback, transposition, tempo, quantization, velocity, and audio-to-MIDI tools.
