Drum machine — first pass of a Hydrogen (https://github.com/hydrogen-music/hydrogen, GPL-2.0+) port. Bundles the stock TR-808 Emulation Kit (ArtemioLabs, GPL) — 16 single-layer instruments (Kick Long/Short, Snare 1/2, Clap, Hat Closed/Open/Pedal, Toms Hi/Mid/Low, Conga, Cymbal, Shaker, Clave, Cowbell) shipped as FLACs under /drumkits/tr808/. Internal 16-step pattern grid drives one-shot sample voices per step; the closed/open/pedal hi-hat triad shares a mute group so a closed-hat triggers chokes the open-hat tail (classic drum-machine behaviour, hard-coded since the source XML doesn't model it). Per-instrument vol/pan/A/D/S/R + mute + solo knobs on the PatchPanel section for that instrument; transport row (BPM 30-300, swing 0-0.75, master gain, PLAY) on the card body. Optional clock_in / reset_in gate inputs let TIMELORDE drive the sequencer (rising edges step the pattern; reset zeroes the playhead); per-instrument trig{0..15} gate inputs let other rack modules fire individual drums directly. DEFERRED to follow-up PRs: drumkit picker / .h2drumkit loader (currently the TR-808 kit is the only kit), per-step velocity (v1 cells are binary on/off), pattern pages + song mode, humanize / per-step micro-shift, multi-layer velocity samples, LADSPA-style per-channel FX bus (use SHIMMERSHINE / CHARLOTTES ECHOS / etc. downstream of the stereo out as patch-cable effects instead), polyphonic MIDI input (pair with MIDI-CV-BUDDY → trig{i} per drum until then).

A multi-kit 16-instrument × 16-step drum machine (named after the open-source Hydrogen sequencer). Each of 16 instrument rows holds a 16-step on/off pattern grid; the playhead walks the steps at the BPM tempo (or an external CLOCK IN) and fires each lit step's drum voice. Pick a kit (TR-808 / TR-909 / LinnDrum / CR-78 / …) with the kit button; every instrument has its own VOLUME, PAN, PITCH, a per-voice low-pass FILTER (cutoff + Q), a full amp ADSR, and MUTE/SOLO — exposed by clicking an instrument's name to expand its knob strip (the patch panel also carries every per-voice CV input + direct TRIG). The whole transport (play/stop, reset, 4 preset slots) is drivable hands-free via the CV inputs, and SWING shuffles the groove. Output is a stereo mix (out_l/out_r) through the master GAIN. Each instrument can also be triggered directly by a gate on its trig{i} input, bypassing the grid — so you can drive HYDROGEN purely as a 16-voice sample player from external sequencers.

inputs

id	cable	what it does
`clock_in`	gate	External clock: each rising edge advances the pattern playhead one step (16th-note cell). Patch a clock here and the internal BPM is ignored — the incoming pulses set the pace. gate / trigger
`reset_in`	gate	A rising edge snaps the pattern playhead back to step 1 (the downbeat) without stopping playback. gate / trigger
`play_cv`	gate	A rising edge toggles play/stop (each pulse flips the run state). Hands-free transport from a patched gate. gate / trigger
`reset_cv`	gate	A rising edge resets the playhead to step 1 — an alias of RESET IN (both reset on a rising edge); use whichever port is convenient. gate / trigger
`queue1_cv`	gate	A rising edge queues preset slot 1 — the pattern + tempo swap cleanly at the end of the current loop (does nothing if slot 1 is empty). gate / trigger
`queue2_cv`	gate	A rising edge queues preset slot 2 — applied at the next loop wrap (no-op if slot 2 is empty). gate / trigger
`queue3_cv`	gate	A rising edge queues preset slot 3 — applied at the next loop wrap (no-op if slot 3 is empty). gate / trigger
`queue4_cv`	gate	A rising edge queues preset slot 4 — applied at the next loop wrap (no-op if slot 4 is empty). gate / trigger
`trig0`	gate	Instrument 1 direct TRIGGER — a rising edge fires this voice once (one hit), independent of the step grid. Patch a sequencer/clock here to play this drum directly. gate / trigger
`trig1`	gate	Instrument 2 direct TRIGGER — a rising edge fires this voice once (one hit), independent of the step grid. Patch a sequencer/clock here to play this drum directly. gate / trigger

Gain	Master output gain (0..2, default 1) on the summed stereo mix (out_l/out_r); 1 = unity, above 1 boosts.
Hydrogen cell {n}	A single step cell in the 16×16 pattern grid (instrument row × 16 steps). Click to toggle whether that instrument fires on that step — lit = a hit, unlit = a rest. The playhead walks the 16 steps and plays every lit cell of every row; the currently-sounding step is highlighted. CLEAR empties the whole grid.
Play	Run/stop state (the PLAY button): 1 plays, 0 stops and silences the playhead. Starting playback resets to step 1. An external clock can still advance steps while stopped.
Kit	Drum-kit selector (discrete) — switches the loaded sample/synth kit (TR-808, TR-909, LinnDrum, CR-78, and others). Per-instrument tuning (vol/pan/pitch/env/etc.) PERSISTS across kit swaps, like a hardware drum machine where 'channel 5 volume' doesn't reset when you load a new kit.
