Virtual Instruments
Synths and samplers, grouped by sound
Browse 600+ instruments by category, from keys, bass, and pads to orchestral, percussion, and layered synths. Tweak each one with its macro knobs, then save your version to use again.
Make the part yours
MIDI Editor & Virtual Instruments: Write the part. Pick the sound.
Record MIDI from a controller or your computer keyboard, clean up timing and velocity in the piano roll, and choose from 600+ built-in instruments. Bring your own VSTs and sound libraries, too.
How it works
Play it in. Fix it after.
Play it in
Plug in a MIDI controller or play on your computer keyboard. Pick a key and scale, and the keyboard marks the notes that fit. Hit record to capture the part, or turn an idea you already recorded into MIDI notes on a new track.
Fix it in the piano roll
Drag wrong notes where they belong. Quantize to tighten the timing, set the grid to fit the part, and adjust velocity note by note to shape the dynamics. Anyone in the project sees your edits as you make them.
Swap the sound anytime
Change the instrument to hear your part with a different sound. Try it on grand piano, a synth pad, or strings. Then use each instrument's macro controls to add interest, movement, and dynamics.
Start with a sound. Or describe your own.
The built-in instruments and effects run right in your browser, with nothing to install. When the library doesn't have the sound you're looking for, ask Moi.
Audio FX
Effects for any track, built in
Compression, EQ, reverb, delay, chorus, saturation, and more, ready to drop on a track. Dial in guitar tones with Amp Modeler, or tighten a vocal with Voice Tuner.
Custom sounds
Describe the sound, and Moi builds it.
Can't find the right instrument or effect? Tell Moi, the agentic co-producer built into Moises Studio, what it should sound like and the controls you want. It creates your unique sound in minutes.
Why Moises
Your sounds, your stems, one project.
Write MIDI where the rest of your song lives, using the plugins and sound libraries you already have.
Write it next to your stems
MIDI, audio, separated stems, and chord markers share one timeline, so the chords sit right above the part you're writing.
Plug in your VSTs
Open the Moises Studio desktop app and load your third-party VST instruments and effects right on your tracks.
Import your sound libraries
Drop SF2, SF3, SFZ, NAM, or ZIP files into your library, and they're ready to use in your projects.
Your collaborators hear it too
Studio renders your plugin tracks automatically, so collaborators hear them without owning the plugin. No bouncing required.
Trusted by pros. Loved by 80M+ musicians.
