Installation Issues

Plugin not appearing in DAW

The plugin may not be in your DAW's plugin scan path, or it may be blocked.

  • 1.Verify the plugin is in the correct folder (see Installation guide)
  • 2.Rescan plugins in your DAW preferences
  • 3.macOS: Check System Settings → Privacy & Security for blocked apps
  • 4.Windows: Try running the installer as Administrator

Plugin crashes on load

This is usually caused by incompatible system requirements or corrupted installation.

  • 1.Verify your system meets the minimum requirements
  • 2.Uninstall and reinstall filament
  • 3.Try loading in a different DAW to isolate the issue

MIDI Routing Issues

No MIDI output to instruments

MIDI isn't reaching your virtual instruments from filament.

  • 1.Verify filament is receiving MIDI (check the input meter)
  • 2.Check that output rows are enabled and have voice assignments in the routing matrix
  • 3.Verify your DAW's MIDI routing is configured correctly
  • 4.Ensure the plugin is loaded in the filament output row

Wrong instruments receiving MIDI

MIDI is going to the wrong instruments.

  • 1.Check the routing matrix—filament uses a routing matrix, so verify which voice layers are connected to which output rows
  • 2.Check other voice layers for conflicting connections
  • 3.Verify you're on the correct keyswitch (each keyswitch has its own routing configuration)

MIDI latency or delay

Notes feel delayed or sluggish when playing.

  • 1.Check your audio interface buffer size — lower is faster but uses more CPU
  • 2.Reduce the Input Delay setting in filament settings if you're a precise player
  • 3.Disable any unnecessary plugins in the signal chain

Performance Issues

High CPU usage

filament itself uses minimal CPU. High usage is usually from loaded instruments.

  • 1.Check CPU usage per track in your DAW to identify the source
  • 2.Enable Multi-Core mode (set to Auto) to distribute processing across CPU cores
  • 3.Use purge features in sample libraries to reduce memory and CPU load
  • 4.Reduce the number of active output rows if you're not using them all

Audio dropouts or glitches

Crackling, pops, or dropouts during playback.

  • 1.Increase your audio interface buffer size
  • 2.Close other applications using CPU or memory
  • 3.Ensure your computer isn't thermal throttling

Activation Issues

License activation failed

The plugin won't accept your license key.

  • 1.Ensure you have an internet connection
  • 2.Copy the complete license key with no extra spaces
  • 3.Check that you haven't exceeded the 3-computer activation limit
  • 4.Contact support if you need to deactivate an old computer

Lost license key

You can't find your license key.

  • 1.Search your email for your purchase confirmation
  • 2.Contact support with your purchase email address
