Downspout VST3 plugins

Downspout

Transport-aware VST3 tools for generated parts, gated movement, and playable disruption.

These plugins are all experimental, mostly work in progress, with various levels of success for their intended purposes.

BassGen plugin interface MIDI generator BassGen Transport-synced bassline generator with style, scale, Moroder/Fugue/Jazz genres, variation, color, and MIDI follow/dodge controls. Campione plugin interface Instrument Campione Multi-zone sampler with per-note MIDI mapping, WAV file loading, audio recording with auto-pitch detection, pitch-shift gap fill, zero-crossing loop snap, crossfade looping, per-zone ADSR/filter/pan, beat slicing, and an embedded MCP server. P-Mix plugin interface Audio effect P-Mix Stereo audio effect for transport-aware probabilistic switching and fades. Bubbles plugin interface Instrument Bubbles Stereo ambient water synthesizer combining subtractive noise, physical bubble and drip modelling, body resonances, wave oscillator, and an LFO modulator — with seven water-environment presets. E-Mix plugin interface Audio effect E-Mix Transport-aware Euclidean stereo gate with density, block, pattern, and fade controls. Bassops plugin interface Audio effect Bassops Four-input sidechain ducker with optional harmonic stereo synthesis. A control signal (typically a kick-drum send) ducks the main stereo signal; the ducked result is summed to mono and split by a complementary LP/HP FIR pair. Distorting the HP path before decoding generates stereo width above the crossover from harmonic content. M-Mix plugin interface MIDI effect M-Mix MIDI gate combining probabilistic bar transitions with Euclidean block patterns. T-Mix plugin interface Audio mixer T-Mix Eight mono strips with manual controls, click-smoothed producer overlays, channel-isolated CC 19 ownership, and MIDI-through. Mixgen plugin interface MIDI control generator Mixgen Eight repeatable mix lanes plus four configurable effect macros for the loosely coupled Producer Control Bus. Loopdelay plugin interface Audio effect Loopdelay Producer-ready stereo delay and looper with BBT time, CC 19 ownership, channel isolation, and MIDI-through. Lightverb plugin interface Audio effect Lightverb Fixed-cost stereo reverb with Producer Control Bus lifecycle, channel isolation, and MIDI-through. Gater plugin interface Audio effect Gater MIDI-controlled audio switcher routing one input to one of two outputs based on note input. MelGen plugin interface MIDI generator MelGen Phrase-aware melody generator with contour, answer, structure, color, range, follow, and strict subject/answer behavior. Rift plugin interface Audio effect Rift Transport-locked stereo buffer effect with live/sample modes, WAV loading, chop/stutter repeats, reverse, skip, smear, and pitch-slip actions. Orchid plugin interface Audio effect Orchid Transport-aware voiced freeze effect that captures stable pitched material and holds period-aligned loops on the host grid. DrumGen plugin interface MIDI drum generator DrumGen Transport-aware MIDI drum generator with fills, style modes, Breakbeat/Jazz/Fugue genres, and sparse pulse options. Xoxolo plugin interface MIDI generator Xoxolo Simple x0x-style MIDI drum pattern editor with note-map presets, per-lane preview, and selectable 8-32 step patterns. DrumKit plugin interface Instrument DrumKit Drum synth instrument with stereo output, MIDI triggering, per-voice controls, and mute strips. Syrinx plugin interface Instrument Syrinx Polyphonic MIDI synthesizer based on the Mindlin-Laje biophysical avian syrinx model, with 10 bird-species presets, chromatic MIDI pitch mapping, and a vertical-slider NanoVG UI. Cadence plugin interface MIDI effect Cadence Transport-aware MIDI harmonizer and comping generator with learned harmony, color, extended voicings, suspended dominants, and arpeggiated phrasing. Arpgen plugin interface MIDI effect Arpgen Meter-aware chord-capture and scale-derived arpeggiator with four traversal orders and triplet grids. Counterpointer plugin interface MIDI generator/effect Counterpointer Learns an incoming MIDI pattern and emits a monophonic answering line with color control. Sidecar plugin interface MIDI generator Sidecar MIDI phrase player for generated solo material with deterministic local generation and optional localhost coordinator requests. Gremlin plugin interface Instrument Gremlin Glitch instrument with six sound modes, scenes, fader-block macros, action triggers, hold pads, and MIDImix LED feedback. Harmonic Atlas plugin interface MIDI generator Harmonic Atlas Seeded autonomous chord and scale guidance with tonal, modal, chromatic-mediant, and neo-Riemannian-inspired movement. Conductor plugin interface MIDI generator Conductor Bar-aligned intro, development, break, reprise, and coda commands for autonomous patches. Drift plugin interface MIDI modulator Drift Four rate-limited seeded CC lanes with LFO, sample-and-hold, walk, chaos, and audio follower modes. Mnemosyne plugin interface MIDI effect Mnemosyne Fixed-capacity phrase capture, recall, transformation, and autonomous recombination. Polymeter plugin interface MIDI generator Polymeter Four Euclidean lanes with independent coprime lengths, rotations, ratchets, probability, accents, notes, and channels. Oracle plugin interface Audio/MIDI effect Oracle Bounded level, onset, brightness, density, pitch-class, and MIDI analysis mapped to guarded CC and note responses. Mosaic plugin interface Sampler instrument Mosaic Four-slot bounded WAV sampler with seeded slices, pitch variation, reverse, stereo spread, and autonomous triggering. Resonance Garden plugin interface Audio effect Resonance Garden Eight bounded damped resonators tuned by held MIDI or an internal scale. Orbit plugin interface Audio effect Orbit Smooth seeded orbit, pendulum, random-walk, and figure-eight stereo trajectories with distance filtering and conservative Doppler. Guardian plugin interface Audio effect Guardian Input gain, look-ahead limiting with attack and release, variable-curve clipping (soft to hard), DC removal, true-peak protection, bypass, and latched fault recovery. Gremlin Driver plugin interface MIDI effect Gremlin Driver MIDI modulation and action sequencer with expanded lane shapes intended to drive Gremlin. Ground plugin interface MIDI generator Ground Long-form bass generator with Grounded, Dub, Jazz, and other phrase styles plus a guarded bass register lane. Floozy plugin interface Instrument Floozy Selectable 1-8 voice (default 4) synthesizer combining distortion sources, physical-model-style excitation, feedback, filtering, modulation, and reverb. Ambo plugin interface Audio effect Ambo Stereo ambient effect with rearrangeable time, spectral, tape, shimmer, delay, drive, and feedback stages. Basilico plugin interface Instrument Basilico Monophonic bass instrument with tempo-synced wobble, acid squelch, and upright/electric/dub/acid/industrial tones. Canticle plugin interface Instrument Canticle 12-voice keys, reed, pad, pluck, and glass instrument for melody, counterpoint, and chord generators. Tuney VST plugin interface Instrument / MIDI generator Tuney VST Focused typing and stored text become microtonal synthesized audio and MIDI through configurable character maps, scales, tunings, and human timing. Luma plugin interface MIDI generator Luma Launchpad-oriented performance generator where lit pads become bass, chord, melody, and drum agents. PaunchLad plugin interface Audio effect/instrument PaunchLad Launchpad dub performance effect with echo throws, sirens, spring splashes, dropouts, and chops. Lifeform plugin interface MIDI generator Lifeform Conway Game of Life MIDI generator where the Launchpad grid evolves one beat at a time. Midiscribe plugin interface Utility Midiscribe Non-destructive MIDI capture plugin that writes recorded events to a Standard MIDI File (.mid) on demand.
