Create a 5-Part String Section in One Pass
Learn how to set up Filament to create a full string section — Violin 1, Violin 2, Viola, Cello, and Bass — from a single keyboard performance.
The Problem
Writing for a 5-part string section traditionally means programming each part separately. You play the violin 1 line, then violin 2, then viola, then cello, then bass. For a single chord progression, that's five passes through the same material.
Filament lets you play once and have all five parts created simultaneously, with proper voicing and voice leading.
Setup
Step 1: Load Your String Libraries
Create five instrument tracks in your DAW:
- Violin 1 — MIDI Channel 1
- Violin 2 — MIDI Channel 2
- Viola — MIDI Channel 3
- Cello — MIDI Channel 4
- Double Bass — MIDI Channel 5
Step 2: Configure Filament Routing
Open Filament and set up the routing matrix:
- Row 1 (Violin 1): Route voices 7-8 (highest notes)
- Row 2 (Violin 2): Route voices 5-6
- Row 3 (Viola): Route voices 3-4
- Row 4 (Cello): Route voice 2
- Row 5 (Bass): Route voice 1 (lowest note)
Step 3: Configure Voicing Mode
Set the chord detection to "Open Voicing" mode. This spreads the voices across a wider range, which sounds more natural for strings.
The Technique
Playing for String Voicing
When you play chords into Filament for strings:
- Play full chords: 5-6 note voicings work well
- Keep the bass clear: The lowest note goes to double bass
- Think in ranges: Stay within the comfortable range for strings
Voice Leading
Filament tracks voices across chord changes, so your inner voices move smoothly rather than jumping erratically. This is key to realistic string arrangements.
Tip: Play slowly at first to hear how each voice moves. Speed up once you're comfortable with the voicings.
Refining the Result
Doubling Options
For a richer sound, try doubling:
- Route voices 7-8 to both Violin 1 and Violin 2 (unison)
- Route voice 1 to both Cello and Bass (octave doubling)
Range Adjustments
Use the range settings per output row to constrain notes to realistic instrument ranges. This prevents viola from playing notes too high or bass from playing too high.
The Result
With this setup, you can play a chord progression once and hear a full, properly voiced string section. Each instrument plays in its natural range, voices lead smoothly between chords, and the overall sound is orchestral rather than keyboard-like.
This same technique applies to any ensemble — brass sections, woodwind choirs, or mixed ensembles. The key is matching the routing to your instrumentation.
