filament

Filament is a real-time MIDI orchestration plugin for composers and producers working with virtual instruments—orchestral libraries, synths, keys, anything that responds to MIDI.

Built to solve a specific problem: getting from one keyboard performance to a playable multi-instrument setup. In other words - it can put a whole orchestra of your own sample libraries at your fingertips.

Instead of duplicating MIDI tracks and manually managing voicings, filament sits between your MIDI input and your instruments and handles the splitting, revoicing, filtering, and routing in real time. This allows you to focus on performance, expression and spontaneity.

Features:

12 Keyswitches – Store 12 complete setups and switch between them instantly and musically.

8 Input Voice Layers per Keyswitch – Each voice has its own routing, range, and chord detection settings.

Intelligent Chord Revoicing – Smart Filter mode distributes voices dynamically, or turn it off for direct control.

64-Output Routing Matrix – Route any note to any output, with per-connection transpose (-24 to +24 semitones).

Phrase Arpeggiator – Not just arpeggios—build complete moving parts with per-step articulations, velocity curves, CC automation, and Euclidean step lengths.

MIDI Clip Launcher – Drop MIDI files into 12 slots per output, edit in the piano roll, trigger and reharmonize live.

CC Modifier – Shape dynamics per instrument, per keyswitch. Draw velocity and CC curves with 128-point precision. VCA channels let one CC modulate another.

Articulation Trigger – Define articulation roles (sustain, staccato, pizz, etc.) and assign triggers. filament translates them into the right keyswitch, CC, or program change for each library.

Plugin Hosting – Host up to 64 VST/AU instruments inside one DAW track. Full mixer with articulation maps, latency offset, and macro CC controls.

Deep Preset System – Orchestrations are separate from libraries. Drag and drop setups across keyswitches. Swap libraries without rebuilding your routing.

Midi Out – Three options for getting orchestrated MIDI out of the plugin - direct MIDI out channels, MIDI drag and drop and a direct integration with Musescore to allow the creation of instant scores.

The design goal:

This isn't an AI "click once, instant orchestra" tool. The idea is to make voicing, routing, and articulation control playable and transparent—so you can experiment quickly, hear what works, and still understand and control the details when you need to.

Works with:

• Orchestral sample libraries (Spitfire, Orchestral Tools, EastWest, Vienna, Cinesamples, 8Dio, etc.).

• Synths and layered textures.

• Multi-instrument keyboard splits.

• Live performance rigs.

• Any MIDI-compatible virtual instrument.

Technical details:

VST3 and AU for macOS and Windows. Tested with Logic Pro, Cubase, Ableton Live, Reaper, Studio One, and other major DAWs. Real-time performance with minimal latency.
