Frequently Asked Questions

Do I need a real PA system?

Not for the in-app training, every drill runs in headphones. Ear training, EQ triage, feedback identification, and decision reflexes transfer directly to a real console. Console muscle memory, room acoustics, and band communication still need real gig reps. Treat this as the daily practice between gigs, not a replacement for one.

I'm a studio engineer. Is this for me?

If you run sound at any live event, open mics, gigs, church, festivals: yes. Live sound skills complement studio work.

How is this different from Studio Mix?

Same belt system, different focus. Live Sound trains feedback identification, gain structure, EQ triage, and venue acoustics. Studio Mix focuses on mixing in the box.

I'm a beginner. Is this for me?

Yes. Start at white belt with fundamental exercises. The system adapts to your level.

Can I cancel anytime?

Yes, cancel through your account. Keep access through your billing period.

Does this include the rest of Main Act?

Yes. Pro unlocks Live Sound plus the full Main Act practice system: Studio Mix, Vocals, Songwriting, and Repertoire.
