PAiA midi2cv8

[Beszedes Arpad]

Hi all!

I don't know about the legal policies of the above device, but I'll ask
this anyway:
I downloaded the schematics for the converter and there are some missing
references, so my question is:

if somebody built this stuff, could he/she tell what the following parts
are:
IC11 and IC12 (guess some FET opamps),
IC6 (74HC04 or what?),
Q1 (2N4124 ?),
Q4-Q7 and Q8-Q15
and also the power supply voltage is not displayed.

By the way, I think that the circuit is really well designed (the system
is especially versatile with this new firmware for the MCU).

Hope I'm not violating some legal rights of PAiA with these questions...
(if I am, please accept my apologies!)

Anyway, thanks for the help,
  Arpad.
