OK, the built units are nominally sold out,but I think I have a floor model or B unit I can fix you up with. I will contact you directly.
One thing to check regarding No MIDI Out. This kit has two nearly identical 16-pin ICs. If they are installed in the wrong locaction or wrong orientation, the MIDI out will not work and the display will go funky. When the PCB is upright, with the row of pots at the bottom, the two ICs are to the left of the display with the divots pointing down, toward the pots. The IC on the left is labelled CD4050BE and the one on the right is SN74HC595N. Humor me and verify these are installed correctly.
