Virtual instruments have
never been better.
World-class orchestras. Instruments recorded in the finest halls. Synths with extraordinary depth. The quality is there.
But making them sound like an ensemble—not one keyboard player triggering patches—that's still the hard part.
“My strings sound like a keyboard player, not a section”
“I spend hours programming each part separately”
“Layering synths means a new track for every patch”
“Everything sounds the same after 8 bars—no variation”
The ultimate real-time performance toolkit.
64-Output Routing Matrix
Your entire setup in one plugin.
filament hosts up to 64 VST/AU instruments inside a single DAW track—orchestral libraries, synths, or any combination you want. Route any of 8 input voices to any output, each with its own transpose (−24 to +24 semitones). Bass voice to cellos at −12, middle voices to violas at 0, top voice to violins at +12—or one chord spread across three synths, each in its own octave. One chord in, full orchestration out.
Musicians are already building Filament into real workflows.
