Thanks for the valuable advice. This mixer seems to be the perfect solution for drums and/or synthesizer voices.
In the case of the PealPal FX module, I have a full effect peadalboard with good power from Strymon. I am currently using the Mooer Ocean Machine (2 x delay, 1 reverb + miniloper). I also have the effects of the Source Audio Sadnblox manta filter, orbital modulator and hot hand set - unfortunately I haven't tested it yet.
In addition, octaver, Dark Glass Bass Overdrive, Ravish Sitar EH and M5 line6. I just realized that with such a number of effects I have to buy another pedalpal module :)
When it comes to double uburst in my rack, explaination is very simply.
The first, white has the Kammerl Beat-Repeat firmware installed and is most often used as the last module for mixed drums. Kammerl Beat-Repeat adds a lot of organic, glitch and life to the final drum sound.
The second Uburst, black, has Parasite firmewaer uploaded and most often serves as a final effect for synthesizer voices.
The peadl pal module is final effect modul for other synthesizer voice or radio modular.
