Ensemble Jammer
Multiplayer music jam
Free · Designed for iPad. Not verified for macOS.
Audiences become performers. One conductor, infinite players. Everyone in harmony, no rehearsal required.
Ensemble Jammer is a multiplayer music app where everyone plays in harmonic sync.
Scale Navigator Dashboard sets the scale and chord.
Ensemble Jammer follows it in real time. When the harmony changes, every instrument updates instantly.
You don’t have to think about technique or theory, you can just play and never hit a wrong note!
HOW IT WORKS
• One person creates an ensemble in Scale Navigator Dashboard where they control harmonic state (ie current scale and chord)
• Others join the ensemble from their phone or tablet via Ensemble Jammer and stay in sync with the harmonic state in real time
• Changes are shared instantly
• Every instrument updates in real time
PLAY TOGETHER
Each player can use the harmony in their own way.
Some follow the chord.
Some follow the scale.
Some play melodies, others textures or rhythms.
Everything stays aligned, even as each part moves differently.
INSTRUMENTS
A set of touch-based instruments designed to respond to the current harmony:
• Touch Harp — swipe melodies and arpeggios
• X/Y Lead — expressive synth control
• Melody Maker — step sequencer that stays in key
• Tanpura Drone — evolving harmonic texture
• Venn Instrument — play chords through overlapping regions
• Sample Sequencer — samples retune automatically
• Sample Looper — loops shift with the harmony
WHERE IT WORKS
Play with people anywhere, or use it on your own.
Coordinate multiple instruments from a single harmonic source, or share a link and play together in real time. It works for jam sessions, performances, teaching, or open-ended exploration.
