Thank you guys. Yes I forgot to check availability, e.g. for the unify module. I cannot really find anything similar as a good alternative though, except Sputnik Modular 6-Channel Stereo Mixer, although I don't need 6 channels maybe and the module takes much space. Can you recommend something?

I put the quadra in as classic straight forward envelopes (4) - honestly I didn't know that Maths would be such thing, I have just seen so many people using it as a multi-purpose tool. Honestly, I don't know what this thing is going to make, I was going to get it and just try what I does.

Should I rather stick to Make Noise and take Optomix instead of the Z2040? Honestly, I am used to straight forward classic modules from my virtual Nord Modular, that's why I was going to get the Z2040. I am a bit uncertain about the possibilities of the Optomix. I read that it is also a VCA, could I omit the uVCA if I take the Optomix?

thanks again in anticipation.
