I will have to get back to on that one. I have loaned my 0-Coast out at the moment, so I can’t plug it in to check. One of the things I have come to love about makenoise products is that they have the quality control of a proper manufacturer, as you expect of a former Moog employee, but they have a lot of authorial modding, almost like a circuit bending quality, to the internal routing. They are also kind of koy about what things actually do. For example they have these ¡¡!! inputs on the new QPAS module that they explicitly do not explain, “to encourage creative patch exploration.”
So I think in part, directly reverse engineering the 0-Coast, might be kind of missing the point. So for the most part I am just using my ears and trying to make the sounds match and the interface feel the same. The actual mechanisms are my own invention.
That said, the more I learn, the more I would like to revise and improve the 1-Toast design and maybe try and make something more accurate and mor my own.
