Hello all

I got my Doepfer DIY synth board delivered last week. Hoorah!

Unfortunately you don't get any more info than is on the site. Boo!

There is a circuit diagram but it doesn't list all of the values for the
pots.  And with my distinct lack of knowledge I don't know if a pot
should be lin or log let alone what value it should be!

So any help with this would be appreciated even if some one could
explain how I work it out.

Listed below are the various modules with the pots required with some
values filled in but mostly not...

VCO
Tune -
Fine tune -
FM (exp) - 
FM (lin) -
PW -
PWM -


ADSR
Attack - 1M log
Decay - 1M log
Sustain - 50k lin
Release - 1M log


VCF
Audio in 1 - 
Audio in 2 -
Frequency -
FM1 - 
Fm2 -
Resonance -


VCA
Audio 1 in -
Audio 2 in -
AM -
Init Gain -


LFO
Frequency - 1M log


Slew Limiter
Slew time - 1M log

Thanks Simon
