OK... I had to watch the Video at least 2 times, your controller not only looks like a work of art (housed in that old Lacie External CD SCSI Box), but it functions flawlessly. I can't imagine how long it took to collect all the data, design the housing, program the CPUs, and machine the box; it looks like a Sci-Fi Telephone Time Machine, not a Hard disk recording (with DSP) controller. You really need to post some pictures of your workshop !
If you ever decide to make MIDI controllers for us guitarists, I would buy one ! I am sure yours would blow away anything commercially available.
I am so glad you have music as a hobby, instead of demolition, because your creation is so cool that it is scary.
