I got the LinnStrument during the pandemic, in June 2021, so it has been over two years for me. It has been eye-opening in more ways than one.
I had no idea what synthesizers were, so the first year I was stumbling around trying to figure out why sounds were not being expressive. The second year I compiled lists of MPE Hardware, and wrote educational reference documents for the LinnStrument’s tritone layout, since there are very few, if any, resources to advance proficiency.
My current skill today is about 1/4 to 1/3 of my piano/keyboard skills, which is over 15 years of self-taught training. Due to the isomorphic layout of the LinnStrument, I do not need to learn multiple fingerings, so I am confident I will be able to fully translate my piano/keyboard experience to the LinnStrument by next year, on top of the MPE.
I still consider it to be the ideal MPE hardware controller because of its key-less design and open-source firmware, but if I had to choose a different MPE controller with “keys”, it would definitely be the Striso, since the firmware is licensed under the GPLv3.
