Expressive E Osmose meets Elastic OSC; playing with MPE

There’s something magical about playing sounds with polyphonic expression. It means translating sound ideas directly to your hands and improvising live, rather than having to go back and edit those ideas in later or take your hands off the keyboard to turn a knob. Here’s a look at playing the presets I made for Elastic OSC using Expressive E’s excellent Osmose keyboard.

Next-gen MPE: Expressive E adds smarter control, $999 MIDI keyboard

Expressive E is making its expressive, multi-dimensional keyboards more accessible, with 49- and 61-key controller Osmose options starting at $/€999. And across the full range, the company’s sound ecosystem is expanding with updated software, including the new Ctrl-e platform for sound. That means it’s easier to afford and get started with these unique MPE keyboards, and you’ll more quickly find ready-to-play sounds.
