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.

A classic algorithmic reverb effect based on the Freeverb algorithm by Jezar at Dreampoint. A Freeverb-style Schroeder/Moorer reverb based on the classic 8-comb + 4-allpass topology, with simplified controls and no stereo spread. This reverb creates lush, spacious ambience through a network of comb and allpass filters. Freeverb is widely used in electronic music production, ambient music, and sound design to add depth, space, and atmosphere to audio sources. The algorithm provides a smooth, musical reverb tail that works well on everything from vocals to synthesizers. This reverb only functions in mono and provides no stereo imaging, and the user can expect the same behavior as a classic Freeverb implementation otherwise.
