FAQ

Questions? We've got answers.

Do I need to know music theory to use Chordelia?
Not at all. Chordelia is designed for musicians of every level. Pick a key and mood, and we handle all the harmony. Roman numeral labels are there if you want to learn, but they're never required.
Can I use my MIDI keyboard or controller?
Yes. Connect any class-compliant MIDI device and Chordelia will pick it up — use it to play along, audition voicings, or tap notes directly into the editor.
Can I route Chordelia into my DAW?
Absolutely. Send Chordelia's MIDI output to Ableton, Logic Pro, FL Studio, GarageBand, or any DAW to drive your own synths, samplers, and virtual instruments — so you're not limited to the built-in sounds.
What can I export?
Download any progression as a MIDI file and drop it straight into your session, or copy Nashville Number System notation for charts and sharing.
Can I use generated progressions in commercial music?
Yes, absolutely. All progressions generated by Chordelia are yours to use however you like — including commercially released music. No attribution required.
How much does it cost?
Chordelia is free to use while we're in beta — no credit card, no usage limits. We're focused on collecting feedback right now; if pricing is ever introduced, current users will hear about it well in advance.
