Had my eye on that one since it came out…I think if one considers the expressive possibilities of MPE (pressure per note, vibrato per note, slides & bends per note etc), I think the Linnstrument has the best layout to use these techniques effectively and quickly. Second is the Seaboard in my book, then the Osmose etc.
What I love about the Linnstrument also is that it is self-contained. All its settings are accessible on the hardware without the need for a special software. Considering how expensive these MPE controllers (still) are and how small the companies who make em often are, it’s good to know that I don’t have to rely on the company surviving and supporting the product for me to be able to use the device.
