I agree. The directions are confusing when it comes to that part. Paia
should really write two separate instruction sheets. One for V/Hz and one
for V/Oct. I hope Simonton is listening...

I think in your case, the answer is No, you dont need V/Hz. V/Hz is only
required for certain rare synths. Most analog synths use V/Oct(1 volt per
octave). So the DAC output goes to the 4051 input.

Look at the directions again more carefully. There is a part where it says
something like:
If you are not going to install the V/Hz board, skip over some steps and
install some jumpers instead.

if you look at the schematic: http://www.paia.com/midi2sch.gif
You put a jumper wire in the place of R32, and another jumper that
essentially shorts the input and output of the daughterboard connector
together.

> second: are all transistors 2n4124?
Not sure what you are asking here... All of them should be standard NPN
transistors though.
