Hi Joe,

Thanks for the explanation. After reading your statement of the "Swiss Army Knife" I wonder why Doepfer hasn't put this in the manuel?? It's so multifunctional that I'm thinking it's no Doepfer, it's a Serge module!!! 
Doepfer gives you some examples, but not how to patch, to get this spectacular results. 
I have this module too, but with the A 116 it's the thoughest one in my system! I tried so many things, I noticed that it can distort, antenuate, but I never manage to get those juicy radical waveshape modifications! And it even can do loads of other things like voltage invert???
Can't you give one patch example how you do it?

Thanks.

cheers,

Roel.

hi roel,
i agree with you on this!!!
please everyone ,give us extensive examples of how you
use your a136.also,i would like to give us examples of
the a116,too...this one is,also,rather complicated
like the a136...
bakis.

I had to get past a frustrating "plateau" with the A136, but I finally 
got a better appreciation of the how to use it by experimenting with a 
single unfiltered sine wave. I realized that if the original audio 
signal is already rich in overtones, harmonic distortion can be very 
subtle and difficult to ascertain. Also, filtering downstream of the 
distortion removes a lot of the high frequency overtones which were 
added by the distortion.

I start by "nulling" the +A, A, and -A knobs to a minimum signal 
level. Then I set the A knob to about 4.5 (unity gain). With the 
clipping level pots at center, slowly adjust the +A pot to the left 
and right and you'll hear an amazing array of tonal colors. Adjusting 
the +L pot adds even more variations. Finally, use the -A and -L 
controls to add a "2nd dimension" to the tone.

When trying the A136 in a more complex patch, its easy to forget that 
our ears are mostly used to hearing distortion applied to guitars, and 
at the end of the audio chain. Learn to swim in the shallow part of 
the pool before you dive off the deep end. Start with the A136 at the 
end of the audio chain , and start with patches that are similar to 
the sounds you're used to hearing distortion on, with lots of sustain.

Happy experimenting.

Joe
