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. Osmose (synthesizer) or Osmose CE, either way you’ll have the same expressive, multi-axis keyboard, and it can map to Elastic OSC without any custom configuration. You only need to enable MPE in your host, keyboard, and Elastic OSC patch (if it isn’t already configured for MPE, as many of my presets are as are various other presets in the bank). Notice what happens with Elastic OSC’s built-in arpeggiator selected: you can continue to transform the pattern by bending and applying pressure to the keys. What’s nice about the Osmose is the range of multi-axis control you get out of each note.…
