Update 2020-05-14
It's come to my attention that several people has been trouble
getting the
octave up switch
working recently.
The PCB has been verified and built succesfully by many many people, but this
sudden trouble with the octave up may be caused by a manufacturing issue on
the latest run of boards.
Luckey, there's a simple fix to get it working. :)
•
Omit/remove R14 and R15 from the PCB and put links there
instead (you can use a cutoff component leg)
•
Omit/remove R13 from the PCB aswell – but don't put a link
there.
•
Solder a short link between the (now empty) top hole for R13
to the top hole/leg of R17 (the resistor next to R13, to the
right).
Even if this shows an unpopulated board, all other components except R13,
R14 and R15 should be installed as normal. The blue lines are the 3 links that
needs to be soldered in.
