Hi Philippepad,
I had the Doepfer A-190-5 and it disappointed me and you might notice that I usually like (or rather love) Doepfer modules, I am quite a fan of Doepfer modules. The exception are those A-190-x modules though, I didn't like to work with the A-190-5, not very logical, menu-diving and the lot and worst of all no manual available.
So I took the Vermona - qMI2 module instead, also 4 MIDI channels module and I love the module for it's simplicity in usage, it just does what it needs to do. I can recommend the qMI2 module instead of a Doepfer A-190-x module.
Depending on what you want to do with your computer towards your modular system, you might want to have a look into Expert Sleepers modules if you need more than that recommended qMI2 module can do.
Good luck with the search for a good MIDI module and kind regards, Garfield.
