Note: in batch #6 we've started to notice that the optoisolators are possibly made to a different specification. If MIDI out and MIDI thru are working but MIDI in is not, try upping R16 to 120 or 150 ohms!

and apologies for the schoolboy error of not reading-the-bloody-manual! hehe...
Have a great day everyone.
