What it does

Listens to you

Plug in and play. JAMiac works out your riff and where each phrase starts, then drops in on the downbeat.

Real grooves

Drum parts come from thousands of bars of real human drumming, matched to what you're playing.

Record your jam

Capture the whole session, guitar and drums in sync, to listen back or share.

Getting started

  1. Download and run the installer. If your browser blocks the download, open your downloads (Ctrl+J) and choose Keep. JAMiac is new and not yet signed with a paid certificate.
  2. Click through the one-time Windows warning. If Windows says “Windows protected your PC”, click More info, then Run anyway. You only do this once.
  3. Follow the setup guide. It opens with JAMiac and takes a minute: pick your input and speakers, and calibrate recording sync. That calibration is what lets JAMiac lock on tight.
  4. Hit Free jam and play. From then on JAMiac keeps itself up to date. When a new version is ready you'll see it at the top of the window.

You'll need: a Windows PC, your instrument, and headphones or speakers. An audio interface gives the best results; a microphone works too.
