I don't know if I would consider this rack "Berlin School". However this is not a bad synth. The Erica edu vco is missing sync which is an important function, so mabey add a syncable vco. Plaits does pretty much everything but mabey not very Berlin School. But who cares, you can absolutely make this setup sound good. I see you have two sequential switches, do you need two ?
The SEM dual filter is a very good choice, but the fixed filter bank i didnt like when i had it, i found it to be pretty much useless but that's just me.
