Expressive Piano – MPE Synth & MIDI Controller
Play expressive music with a powerful MPE synthesizer designed around a familiar piano-style layout. Slide between notes, control pitch per finger, perform microtonal music, and create highly expressive performances with natural gestures and multidimensional touch control.
Expressive Piano combines a virtual analog synthesizer, expressive MIDI controller, and microtonal performance instrument into one powerful music production tool. Perfect for electronic music, cinematic sound design, ambient music, jazz, Arabic music, Indian classical music, experimental music, live performance, and expressive solo playing.
Inspired by expressive instruments and MPE workflows like GeoShred-style performance systems and Seaboard-style controllers, Expressive Piano helps musicians explore expressive digital performance using a familiar 88-key piano-inspired playing surface.
