DIY touch-sensitive grid keyboard (Linnstrument inspired)

A walk thru of my new DIY midi controller, which is inspired by the Linnstrument, spans all 128 midi notes, and is inexpensive to make. It's also friendly to microtonal /xenharmonic tunings, and has polyphonic aftertouch. Some thoughts I didn't mention in the video: This instrument has velocity sensitivity, and polyphonic aftertouch. It's not MPE compatible, and doesn't have the other dimensions of expression that you get on a true Linnstrument (per-note pitch bend on the X axis, other controls on the Y and Z axes, etc. and there aren't any lights to help you identify notes. I just focused on creating a big grid of note pads that would be sensitive enough and respond fast enough for a musical instrument. Roger Linn's site has fascinating information on how the Linnstrument's hardware is built, and boy howdy is it cool! I could never create something with that amount of complexity, but using the materials to do something simpler turns out to be really feasible! The Linnstrument is patented, but the information I used to come up with this was freely available, and I'm not selling anything, so I don't think there's any harm in using or sharing this stuff w/ the DIY community. The Velostat material that makes this possible is very affordable, and unbelievably useful. You can use it to make pressure-sensitive pads, XY touchpads, ribbon controllers, and so on. I got my 2 sheets from adafruit.com for less than $10. The microcontroller that does all the computing and reading is a Teensy LC. They are probably going to be discontinued, but there are even more powerful successors to the Teensy LC at pjrc.com. The velostat is a single solid sheet, in between a set of 16 rows of copper tape and a set of 16 columns of copper tape. The microcontroller sends some voltage through the row strips one at a time, and reads how much voltage passes through the velostat and into the columns one at a time. The harder a finger is pressing on one spot, the higher the voltage is read. Man, I should probably just write a blog about the technical stuff. Disclaimer: I don't have a ton of free time these days, and I'm not a great video producer, so I'm focusing my time on projects rather than making great videos. I really want to share the stuff I make, especially when I think it might appeal to or help other folks though. So I hope you don't mind my videos being simple and raw! I'm not on YouTube to make money or grow a big subscriber list.
