Doepfer

Does anybody knows if there is a significant difference in sound between a Dark Energy 1 (or A-111-5) and the Doepfer DIY-synth?

TIA,

Danny

i'm not Dieter (sorry ^_^ ), but as i understand it the various DIY synth possibilities are more or less based on the circuitry of the A100. the Dark Energy 1 is based almost entirely on a single Curtis chip, basically and entire synth voice on one chip (it was originally used in the Sequential Circuits Six-Track & Max early multitibral synths from the mid-80s) - this chip is no longer made and became so rare that's why Dieter had to discontinue the DE1 and completely redesign the voice circuit for the DE2.
i have a Lot of A100 modular, a DE1 & DE2, and they all sound subtly different from each other. actual differences in sound are difficult to describe becuase such things are so subjective, but the DE1 to me sounds a bit fuller and "beefier" than the DE2, which seems more "sharp" and has an "edge" to the sound... and yes those are all very precise scientifically-based audio engineering terms. ;-)   and of course the A100 can ptentially sound like either of them or something else entirely depending on which modules you choose.
just my 2 cents!  :-)

Hello

As far as I know the DIY synth and the DE2 are quite similar (if not 
equal). The only difference I find is the clipped Saw at the DE2



@Christian: Your impression that the DE1 is beefier than the DE2 should 
be caused mainly by the circumstance, that the DE2 uses a exponential 
VCA for the Envelope, while the DE1 uses a linear VCA.


Of course there everyone can use any type of VCA he wants. But to my 
opinion the VCA for the loudness envelope should be linear, since the 
envelope itself has an exponential curve already.
Exponential VCAs are intended for linear control voltages like LFOs or 
velocity.

It depends if you mean the Dark Enery I or II. The Dark Energy I is totally different from the DIY synth. But many parts of the Dark
Energy II are very similar to the DIY synth with only a few exceptions (like the clipped sawtooth of the Dark Energy II, two LFOs of
the Dark Energy II).

Thanks Dieter,

That's exactly what I wanted to hear. I have an A-111-5 in my rack, which is similar to the DE 1, imo. Now I can buy a Doepfer DIY-synth and complete it with the very good looking and full of features "XAOC Devices - Karl-Marx-Stadt".
Thanks again, have a nice weekend,

ah, very interesting, thank you Florian! must begin more new experiments immediately...

and yes, things like "beefier" are so entirely subjective to begin with anyway. only in music tech would you find professionals using terms like "beef", "sparkle", "oomph", "bright", etc as precise enginerring terminology! ;-)
