So they built a Linnstrument? Honestly don't know who was first, but I know I looked at the Linnstrument a long time ago (when my daughter Linn was really young, she's 13 now).
The Linnstrument looks better and has more buttons, and more is better, right?
The idea behind Push is you can control everything in Live with it. It's not a generic MIDI controller like a Launchpad. It's a full hardware interface to a specific piece of software.
I own a Linnstrument. I used to own a Push 2. They're very different.
Everything has (or will eventually have) MPE so everyone is "just building Linnstruments", just like everyone has been "just building MPCs".
The touch interface of the Linnstrument has limitations that the Push probably doesn't. For example, the Linnstrument can register no more than three simultaneous touches in a single column.
And Linnstrument is open source. And is a generic MIDI controller that works with any MPE compatible synth and any MPE VSTi instruments - such as Audio Modeling. The Push doesn't support VSTi.
