For producers, live engineers & lighting designers
Know exactly what to practice today.
Take a quick diagnostic, get a daily practice plan, and build real instincts across studio mixing, live sound, and lighting design, all under one belt. Active drills measure progress instead of giving you more tutorials to watch.

Your result becomes your plan
A score is only useful if it tells you the next rep.
Each free diagnostic names the weak spot, saves it through signup, and points the first daily session at the thing that slowed you down.

What happens after the click
Your first session is prescribed, not browsed.
1. Diagnose
Name the actual gap
Free tests turn a fuzzy problem into a concrete result: a frequency you can't place, a feedback ring, a compressor you're guessing at, a masked element.
2. Practice
Start the next rep
Main Act picks the first drill and keeps the session short enough to finish today.
3. Adapt
Progress changes tomorrow
XP, belts, review queues, and concept gaps update so the next session is different on purpose.

Three disciplines, one daily plan
Start with the pain you feel today. Main Act can lead with your mix, your live room, or your lighting rig, then connect the adjacent skills once you have momentum.

Studio Mix
Stop guessing what your mix needs.
Today's rep
Hear a boosted frequency band, pick it, then compare against the clean mix.

Live Sound
Practice show-day decisions before the room depends on you.
Today's rep
Find the feedback ring before it blooms and lock the reaction into muscle memory.
Lighting
Design and call stage lighting that moves with the music.
Diagnose. Practice. Adapt. Progress.
A quick result becomes a focused session. Each session updates the next one, so you spend less time deciding and more time improving.

Diagnose the gap
Start from a real result: pitch, range, frequency hearing, feedback, songs, or writing.

Practice the next rep
Main Act turns that result into a short session across the skills that reinforce each other.

Track visible progress
XP, belts, streaks, and review history show whether the work is sticking.

Train anywhere
Works on phone, tablet, and desktop. Your practice plan syncs everywhere.
The origin story
A music school usually needs a faculty of fifty. This one was built by two.

Frequently Asked Questions
How is this different from YouTube, Soundgym, or a mixing course?
You are not watching videos or playing one-off ear games. Main Act prescribes a short daily session, tells you exactly what to drill, and adapts as you improve, all in your browser. YouTube and mixing courses are passive video; Soundgym is mostly standalone ear games. Main Act is active drilling across studio mixing and live sound.
What's included in the subscription?
Full access to all three production disciplines: Studio Mix, Live Sound, and Lighting. Unlimited drills, full belt progression, Ask Coach AI mentor, Mix Analysis, and every future update. The same subscription also unlocks the entire Main Act artist system (Vocals, Songwriting, and Repertoire) at no extra cost. One subscription, one account, both systems.
Is there a free tier?
Yes. Each school has a free tier with daily caps and a green-belt ceiling, enough to actually practice and feel the system before you decide to upgrade. The free tier is real and stays free; no card required.
How does the 7-day trial work?
Start any paid plan and get 7 days free. Cancel before the trial ends and you won't be charged.
Can I cancel anytime?
Yes. Cancel through your account settings. You keep access through the end of your billing period.
What if I try it and don’t like it?
30-day money-back guarantee on every paid plan, monthly, yearly, or lifetime. Email support@mainact.app within 30 days for a full refund, no questions asked. The free tier is also genuinely free forever, so you can also just use that.
Do I need experience?
No. Each school starts from the fundamentals and adapts to your level through the belt system.
What if I only want one school?
The subscription covers everything, but you can use just one school if you prefer. Many engineers discover new skills they didn't know they wanted.
