One keyboard. A whole ensemble.
Load up to 8 VST3 instruments, set your note ranges, and let MultiSolo figure out who plays what. Violin takes the melody, cello handles the bass line, viola fills the harmony — all from your single MIDI input. MPE fully supported, every bend and slide lands on the right instrument.
Currently available for macOS only.
Here's the deal
MultiSolo lives in your DAW as a plugin. Drop instruments into its slots, tell it how to route, and play.
Smart Note Routing
Split your keyboard by note range — high notes to violin, low notes to bass — or go round-robin and let MultiSolo hand out notes one by one. Your call.
Any VST3 or AU Plugin
Soliste, Spitfire, Kontakt, your favorite synth — if your DAW can load it, MultiSolo can host it. Up to 8 instruments at once.
MPE? No Problem.
Pitch bends, slides, per-note pressure — MultiSolo keeps every MPE message on the right channel heading to the right instrument. Play expressively, it just works.
Mix Right Inside
Volume faders, pan knobs. It's a mini mixer in a plugin. Run up to 4 instances of the same plugin in a slot for instant polyphony.
Why we built this
Playing a string quartet from a single controller should be fun, not a routing nightmare. We got tired of setting up elaborate MIDI splits and channel configurations every time we wanted violin, viola, cello, and bass to play together from one keyboard. So we built a plugin that does it for you.
It ships with a ready-to-go Soliste String Quartet preset — load it and start playing instantly. But it works with any VST3 or AU instrument, so go wild. Layer synths, split drum machines, build orchestral sections — whatever you're into.
We're in alpha right now and looking for musicians to help us make it great.
