Hello Karel,

I assume the serge module is not buffered very well, so its input 
creates an lowpass together with the output of the A-138.
I suggest the following test.

A-111 -> A-138 -> multiple

connect cubase with the multiple. Check the waveform and the frequency 
range.

Then connect the SSG to the multiple too (cubase still connected to the 
multiple). Check the waveform and the frequency range again. I assume 
there will be a drop in the high frequency range. If yes, blame it to 
the SSG.

regards
Florian
