Ensemble Jammer vs GrooveMeter

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. FEATURES • Real-time sync with Scale Navigator Dashboard • Instruments adapt to scale or chord automatically • Smooth transitions when harmony changes • BPM sync for sequencers • Works on iPhone and iPad • Free to use Part of the Scale Navigator system.

GrooveMeter is a real-time BPM (Beats Per Minute) meter and practice tool for musicians who want to improve their timing. It listens to your playing through the microphone and continuously detects your tempo, making it easy to see how steady you really are. GrooveMeter runs as a stand-alone app or as an AUv3 plug-in inside compatible AUv3 hosts such as Logic Pro, AUM or GarageBand. Simply open the app, grant microphone access, and start playing. Within seconds, your tempo appears on screen and updates in real time. The main BPM display shows a smoothed tempo reading alongside a confidence indicator, so you can tell when the detector is certain about what it hears. When the audio is unclear or too quiet, GrooveMeter's confidence indicator will let you know by dropping to a lower percentage. A scrolling BPM history graph visualizes how your tempo changes over time. You can adjust the visible time window and set a target BPM to get immediate feedback on how close you are to the desired tempo. Color cues show whether you are on target, slightly off, or drifting significantly. Tap tempo is built directly into the graph. Tap in time to get a quick read on your tempo manually, which is useful when you want to compare live playing against a tempo in your head rather than relying on audio detection. GrooveMeter can record practice sessions, capturing both mono audio and a BPM snapshot every second. After recording, you can scrub through the session, see the tempo at any point, and review overall statistics such as median BPM and tempo stability. All recorded sessions are stored locally and accessible through the session browser. Each session includes clear statistics like duration, median BPM, minimum and maximum tempo, and a stability percentage that reflects timing consistency. Sessions can be exported as a zip archive containing the raw audio recording and a PDF practice report. The report includes a BPM timeline graph, summary statistics, and a written assessment of your timing with practice-oriented feedback.
