The band that hears you.
Play one note and a band arrives. Jam It Bro listens to what you actually play — your chords, your key, your timing — and puts musicians around you in real time. It is not a backing track. It is a band that is listening to you.
No spam. One note when the beta opens.
VST3
Jam It Bro listens and plays along.
A loop cannot tell that you slowed down, changed the chord, or left a bar of space. A band can. That single difference is the whole product.
Nobody should learn alone.
Music used to be learned in a garage. Four kids, one amp, and whoever turned up on Saturday. You learned to play by playing with people — badly at first, then less badly, then together.
That happens far less now. People learn on their own, in headphones, in a bedroom, next to a metronome that has never once listened back. You can practise for a year and still have never played with anyone.
So we give you the band first. Musicians who wait for your count, follow your chord, hold the groove when you rush, and leave space when you leave space. You get to practise the thing you actually wanted to learn — how to play with other people — from your very first session.
It is not about replacing musicians. It is about making sure that nobody gives up in the months before they find any.
The chairs are not meant to stay ours. Every seat the band holds is a seat a real person can take — your teacher, your friend, your first group. We are building toward the session where you hand a chair to someone real, and toward the stage after it. That is the whole point: to get you comfortable playing with people, and then out there with them.
Five musicians. One empty chair.
This is not a guitar tool. Sit down as the drummer, the bassist, the pianist, the guitarist or the synth player — whichever chair you take is left empty, and the rest of the band fills in around you.
What makes it a band
Four things have to be true before a machine can hold a chair in your band. All four are working today.
It hears harmony, not just pitch
Major, minor, power, dominant 7, major 7, minor 7, sus2, sus4, diminished and augmented are recognised and carried all the way through to the notes the band plays back.
It runs on your machine
Listening happens on your computer. A local AI model does the hard part on-device, on a low-priority thread so it never steals time from your playing. Nothing you play is uploaded anywhere.
Controls that change the playing
Power, Busyness, Surprise and Human Feel are not decoration. They change which notes the musicians choose and where they place them.
Five styles, real vocabulary
Cinematic, Neon Pulse, Indie Drive, Heavy and Minimal each carry their own note and rhythm vocabulary. Changing style changes the playing, not just the tone.
Direct them mid-song
Solo a musician, mute them, or call a fill of one to four bars while the song keeps running. You are the bandleader, not the audience.
App and plug-ins
Use the standalone app, or drop the plug-ins straight into your DAW: one Listener, and a Player per chair writing MIDI into your own instruments.
Plug in. Play. The room fills up.
Pick your chair
Tell it which instrument you are playing. That seat stays empty, and the band is built around it.
Play something
Guitar, keys, bass or voice, through audio or MIDI. It works out the chord, the key and where the beat is sitting.
The band comes in
They arrive on your count, follow your changes, and leave space when you leave space. Solo, mute or call a fill as you go.
The app, running. The guitar chair is empty because the player took it.
Start free. Grow into it.
The band is free to begin with, and it runs on your own machine. The paid plans are subscriptions, priced so that anyone serious about learning can afford to keep playing.
- A real band, free — not a timed trial
- Runs on your device, listening included
- Enough to learn to play with a band
- No card to begin
- The full band, in the app and in your DAW
- Every style, every chair, every control
- Record the jam and keep the MIDI
- Local listening — nothing leaves your machine
- Everything in Pro
- Built for performance, not just practice
- Deep personalisation — a band that sounds like your band
- Set-ready control while your hands are busy
- Guided jams that show you what to play
- An analyser that reviews the session afterwards
- Suggestions based on what you actually played
- Learn with a band, not against a metronome
Paid plans are subscriptions. Editions are in active development and pricing goes to the early-access list first — we would rather more people keep playing than charge a few people more.
Works where you already work
A standalone app when you just want to play, and plug-ins when you are already in a session.
The Player writes standard MIDI into whatever instruments you already own, so it runs anywhere VST3 or Audio Units are supported. Pro Tools is not supported yet — it requires AAX, which we do not currently build.

Piruz Labs is an independent audio software studio, with a catalogue of instruments and effects and its own storefront, licensing and delivery already running.
Jam It Bro is not a side project launching into nothing. It arrives on infrastructure that is already running, from a studio that already ships.
Nobody quits because they stopped loving it.
Ask anyone who put the guitar back in the cupboard and they will not tell you the chords were too hard. They will tell you they were on their own. No bandmate. No one waiting on a Tuesday night. No fuel left to carry it alone.
That is the part I wanted to fix. Not the teaching, there is plenty of teaching. The company.
Jam It Bro gives you the bandmate first, so you have a reason to pick it up tomorrow.
Your favourite drummer, your bass player, the keys player who actually listens to you. They follow what you play, not the other way round. You are never practising. You are always playing with someone.
And then the real point. When your confidence is there, you swap them out. One seat at a time, for real people, in online sessions. Humans just like you, on the other side of the world, who also stopped for a while and also came back. The AI band is the bridge, not the destination.
We musicians are a bleeding heart community. We always were. Love to all of you, my brothers and sisters everywhere, with my deepest feelings, through my music and through my software.
Cheers, bro.
