Thanks again Timo!
The patch is already that great
It did play around with it (not too long at the moment) and the only thing I managed is to softn the attack.
I think I have to learn very much. The patch looks not very complex (eg. no matrix if I am not wrong), but even if I try very small changes it either do nothing or makes it totally strange.
Additionally I thought that the max of Unison would always improve the sound. No it didn't (I used different detune). Also I thought OSC2 would improve the sound (same settings as OSC1). No it didn't.
But I already learn a small bit: At LFO1 it is not necessary to use ASSIGN AMT when using one of the targets OSC1/2, PW1+2, ...
But I keep going ...
