Mouse Synth Lab

+ Zieh deine Maus durch den Pad und verwandle Bewegungen in Klang. Drei LFOs, + FM-Experimente und ein Delay/Distortion-Hybrid werden live verschaltet. + Die Bitcoin-Feeds von Coindesk () + und CoinMarketCap () + mischen das Routing zusätzlich – sogar die Uhrzeit entscheidet, welches Instrument + sich meldet und wie die Resonanzen pulsieren. +

+ Tipp: Halte die Maus gedrückt, damit der AudioContext aktiv bleibt, und lass den Cursor + Kreise fahren. Je nach Bitcoin-Laune (Coindesk + CoinMarketCap) und Tageszeit schalten + sich neue Instrumente, Delays und Resonanzen zu. +
