The amazing Roger Linn Linnstrument! It's really exciting to see and hear developments on this project.
When you have 40+ mins to spare, check out this great video of Roger Linn demoing the new LinnStrument. Along with discussions on other new Expressive Controllers.
Roger Linn on LinnStrument and new Expressive Controllers (Moogfest 2014)
Roger Linn introduced his last version of the LinnStrument at Moogfest and talks about the importance of expressive controllers, this is the full recording of his lecture. I gave a short demo of the Eigenharp as one of the examples. I've started helping Roger out with programming the LinnStrument software, since I think that it's a great solution from people coming from existing grid controllers.
