I definitely can subscribe this. The A137 is my favourite module from 
the first moment.

Don't mix the input signal. Use one VCO as carrier and the other as 
Modulator (I call it 'waveshaping cross modulation')!

This is not a trouble it is the best feature and one really important 
note for every use of a wavemultiplier or distortion is:
If you want to modulate the effect dynamically (Envelope, LFO, ...), the 
it is much better to modulate the level of the input signal instead of 
modulating the waveshaping effect.


Example:
Not good:
         ENV
          |
VCO -> A137 -> VCA

Better:
        ENV
         |
VCO -> VCA -> A137


The best (and most simple) example is feeding a TR808 style drumset with 
bass drum and different toms through the A-137. Use only very short 
Hihats and no noise like clap or shaker.
