Re: [Doepfer_a100] System Planning - a few more questions

JKN,

Looked over your layout - looks good.
Not the modules I would have chosen, but 
it's great that you can choose exactly what 
suits you!

If you have any doubts about the WASP filter,
I highly recommend the A-108 VCF.  4 different 
LP slopes available simultaneously and a fine BP, 
Plus it has VC Resonance.  Regrettably it is 4 HP
wider.

If you are thinking of putting in a mixer - I 
recommend the A-138c.  If you invert and mix
you can use it to turn BP filtering into Notch,
and LP filtering into HP.  Or you can mix inverted
waveforms from the same VCO to subtract harmonics.
Or invert the sine and mix it with any of the other waves
to subtract the fundamental.

Shawn may have a few words to say about which of the 
three smaller mixers is best for our needs.  I take his	
recommendations seriously.   (Although it is too late for 
my suitcase.)

And while on that subject. are you putting this combination
into a suitcase?  If so, be prepared for some interference 
from the power supply.  Or, if you find NO interference,
by all means let us know!!!

You're gonna have some fun!
