About this app

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.

Ratings and reviews

Amazing. However, I wish all presets had vertical slide control as default, that's like the best part of the app, I feel like the presets used to be somehow more intuitive, idk for sure. The preset selector menu could fit more names into screen at once, there's so much space wasted. Also search tags / categories would be cool. Also small arrows to change the preset without menu. Maybe "Advanced mode" with more buttons visible? Thank u any case, fire app

This is my Second review since the V2 update. I previously wrote a bad review but I'm amending it. The V2 update is actually GREAT!! Just not with the default settings. If you play around with the settings (modulation especially), you can actually get a great sound. The devs responded to my previous review, so hopefully they'll see this too. Please improve the default settings or add a manual of some sort. This app has tons of potential. Thanks!! — An interested consumer.

most underrated synth, there's so much you can do with this app or even use it as a midi controller. everything is perfectly laid out and the tones are amazing. absolute pleasure using this.
