So i decided to look into it, and started with a couple of modules. just an output and a sampler & repeater, which turned out to do more than its intended for.
setup below
*As you see above i eventually got round to buying a few more to build up a system to create music with, be it techno to drum&bass, i have to say anyone who is into going this route, you'll be going down a rabbit hole as my friend said, and also it'll be costly, because the range of one module can cost from £20 to £2000 upwards, if getting seriously into modular. I spent little here as seen, these are mostly the standard ones most will buy to use for their purposes.I hope to expand the racks when venturing out more.
