Pick a track, program a tempo-synced grid of glitch effects on it, and render the whole pattern down to a downloadable WAV — in the spirit of Illformed's Glitch 2. Seven custom AudioWorklet effects (bitcrusher, ring modulator, filter, delay throw, buffer repeat/stutter, reverser, gate) run on a per-track step grid from 1/1 down to 1/64, plus triplet divisions. Every step's dry/wet crossfade is driven by native AudioParam automation, so playback stays sample-accurate regardless of JS event-loop jitter. When you're happy with a pattern, render it offline through the exact same effect graph as live playback and download a 16-bit WAV.
*All effect processing and rendering runs entirely in your browser — your audio is never uploaded to a server

No. Drillin's mixer, effect worklets and WAV renderer all run entirely in your browser via the Web Audio API — your audio is never uploaded and there's no server round-trip.
Seven tempo-synced glitch effects: Bitcrusher, Ring Modulator, Filter, Delay Throw, Buffer Repeat (stutter), Reverser and Gate — each with its own knobs, a randomize button and a clear button, programmed on a per-track step grid.
Yes. Render the current pattern (1/2/4/8 bars) through an OfflineAudioContext using the same per-track effect graph as live playback, and download it as a 16-bit PCM WAV.
