Hi Garfield !
Thank you very much for your honest opinion and for the advises !
So if I understood you correctly you think it is not worth it to expand on the 0-coast ? Of course I want to go full modular at some point and get a nice case with VCOs, VCAs, etc. but as you said I would like to start simple. That's why I thought adding some extra functions to the 0-coast like an additional voice such as plaits that I could mix into the balance section of the 0-coast or getting stages for modulations could be a nice introduction and learning experience.
Thank you very much for your insights.
