Thank you, @Hawkeye!
@gotkovsky I know you got it running (awesome) but in case anyone else has a 'not found' issue in MIOS studio, I had the really large USB switch set wrong - the one between OTG and regular USB mode. Once I switched that it showed up fine.
On a side note, I definitely appreciate the multiple, smaller PCBs vs one or two huge ones. I did a NAVA build a year ago and that took seemingly forever and was just too unwieldy.
Lastly, I was able to load the project.hex file posted from Hawkeye in an earlier post, but is there a newer, official build by TK for this? I have been looking and only found the SVN, no idea how to compile..was hoping the latest firmware binary would just be able to download somewhere obvious. I have a ways to go in this build and can only work a little bit at a time so I'm not too worried right now. However, if there is a seq v4+ firmware version specific to this kit, might be helpful if it's available on the midiphy page. Just a suggestion.
