Doepfer MCV1

[Erik Schuijers]

Hi everyone,

as you might know I'm building a MCV1. But, you already guessed it! It
doesn't work! I've built the Elektor version (or in Dutch Elektuur).

When I turn on the power supply the LED sometimes starts to blink. BTW this
is not the software version which reads out the Midi channel (and so it
should NOT blink!). The Gate is ALWAYS high, the output of the CV always
low. It doesn't respond to MIDI whatshowever.

Has anyone ever built this unit succesfully? Please... I'm getting
desperate.

Erik

PS: The voltage which makes the LED flicker is also full of HF noise!
