Hello Mixxalot, thank you for the advices, The Tanzabar looks nice. and been considering a packaged modular system.
I have now taken a look at the Modulor 114 and Phenol systems. I am sure they are nice for a start. But i am 100% sure this is something i want to do, to build a big system. The Mantis case from tip top i feel already is too small, but i will keep it for portable use. I am thinking to build a case on the size of, Pittsburgh Modular Structure EP-420 Desktop kabinett, and i like the Doepfer 100 monster cases.
I want to have a full wall. so i have more options in the future for designing unique sounds, regardless of cost.
I intend to go all in, and expand for the next 40 years or more, as long as i live and are able to be creative.
I allready want more Sequenser options.

Thank you for answering me :D

i did not know about the machines you mentioned.
