Roger Linn (@roger_linn) gave us new ideas about musical instruments, detailing how wonderful expressive control, 3D buttons, and keyscanning can be. Roger's company is Roger Linn Design. We talked extensively about the LinnStrument, some about the AdrenaLinn for guitar, and only a little bit about the analog drum machine Tempest. A key matrix circuit is a popular way to handle a large number of buttons but it falls prey to n-key rollover. Roger adds force sense resistors to this (FSR example at Sparkfun). If you have an idea for an instrument, Roger has already written his response to your request for a prototype. Roger gave a keynote address at ADC '16 about the LinnStrument, including showing the sounds it can make. OHMI Trust is the one handed musical instrument society enabling music making for everyone.   Roger mentioned some other expressive instruments including: Roli Seaboard Haken Continuum Madrona Labs Soundplane Eigenharp
