Eigenlabs notes that the new Spectrasonics Omnisphere 1.5 unleashes some latent Eigenharp power:
Arguably the most important feature of the Eigenharp are the touch3D keys, which respond to pressure, velocity, roll and yaw.
Spectrasonics have added new support for the kind of multi-channel MIDI the Eigenharp can produce - which means you can now indepedently pitch bend, distort and generally mess around with Omnisphere's fantastic sounds in note-by-note polyphonic glory.
It's a rare combination of capabilities that could open up new options for musicians interested in exploring technique beyond what you can do with typical keyboard MIDI controllers.
See Sonic State's coverage of the Omnisphere 1.5 introduction for full details on what's new in the updated software synth.
