JamJamz questions, answered

JamJamz is in private testing and not open to the public yet. Join the waitlist at jamjamz.io/waitlist and we will email you when early access opens. We invite people in small groups, and telling us which kit you play helps us decide who goes first.

JamJamz is a drum practice app that teaches real drumming on an electronic kit, one section at a time, using songs from your own Clone Hero library. It loops the part you pick, slows it down without changing pitch, judges every hit from your kit, and raises the tempo as you get it clean.

No. JamJamz is a teacher, not a game. There are no scores, combos, star power or leaderboards. It measures how close each hit lands to the real drum part, tells you which limb is early or late, and helps you build one section up to full speed.

You need songs in the Clone Hero folder format: a song.ini file plus a notes.mid, notes.chart or .sng drum chart and the audio. You do not need to run the game. JamJamz does not include or sell songs, and it is not affiliated with Clone Hero.

Yes. JamJamz reads your playing from an electronic kit connected over USB-MIDI, so it can time every hit precisely. Acoustic kits are not supported. The kit makes the drum sounds; JamJamz plays only the song audio, with the drum track muted or kept in.

Desktop Chrome and Edge. JamJamz needs Web MIDI to read your kit and the File System Access API to read your song folder, and those two browsers support both. Brave works after you enable its file system access flag. Safari, Firefox and phones are not supported.

JamJamz will be a subscription. The draft plans are Free at $0 and Pro at $9 a month, or $90 per year billed annually. Prices are not final, and nothing can be bought yet. Waitlist members hear about final pricing first.

Yes. The draft Free plan covers the core practice loop: any song in your library, section loops with a count-in, pitch-preserving slowdown, hit-by-hit timing, and kit mapping. Pro adds the automatic tempo ladder, saved progress, per-limb timing over time, and hands-only or feet-only practice.

No. JamJamz never sells, hosts or ships songs. You practice with the songs already in your own library, and JamJamz reads them on your computer. The subscription pays for the practice tools, not for music.

No. JamJamz reads your song files in place, on your own computer, through the browser's folder access. Audio, charts and song files never leave your machine and are never copied or changed. Only events about your practice, such as which notes you hit and when, are sent to JamJamz.

Your progress, kit map and calibration are saved in your browser. Practice events, such as the notes you played, pass results, calibration and errors, are sent to JamJamz servers so practice can be reviewed and coaching improved. Song audio and song files are never sent.
