Is it a plugin?
No. Gavna Music Composer is a standalone Windows app that works next to your DAW: you drag the result into it as MIDI.
Does it work with my DAW?
With any DAW that accepts MIDI files: drag a slot or a group onto a track, or export a .mid file and import it.
Do I need to know music theory?
No. The suggestions and arrangement techniques do the theory for you, and each one explains what it does in plain words. If you do know theory, you'll find degrees, modes and substitutions ready to use.
Does it use AI to write the music for me?
No. Every suggestion comes from music-theory rules you can see and follow, and every decision is yours. Gavna Music Composer is built to empower your creativity, never to replace it.
Is there a Mac version?
Not yet. Gavna Music Composer runs on Windows 10 and 11.
What happens when the trial ends?
The app asks for a license key to keep opening. Your projects are saved as files on your computer and stay yours whether you buy or not.
Is it a subscription?
No. You pay once and the license never expires. Every version 1 update is included.
Can I get a refund?
Purchases are final, because you can try every feature free for 15 days first. We refund in full if, within 14 days of your purchase, the app doesn't work on your computer and we can't fix it, or if you were charged twice. The details are in our Refund Policy.
