Hi all,
Quite some time ago, I discussed the idea of doing something useful with the external input of the CS80. So I came with an idea to build me an LFO module. With help from a friend I designed the module and I made one myself and ordered / manufactured some extra parts to build some more of these units. I invite you to have a look at my website www.lfo-expander.com
I'm planning to build some more units and sell them to people interested. I have parts for max 20 units to give you an idea. It's not ready for sale yet (have to do some work and have to find time).
I'm very curious about what you think about the idea.
