I like this one. I think the logic modules are a problem for some users, even some experienced synthesists, because they have no obvious equivalent in most synthesis environments. Smallish patches concentrating on one or two main points are easier to study. |

When I was a lot younger, I met Stanley Lunetta in California. I immediately became a deciple. Stan was making home brew synthesizers out of chips and other parts he got a local electronics surpluss stores. At that time we could get SSI and MSI parts very cheaply. We built oscillators by hooking up inverters in feedback loops with RC, resistor cacitor, networks to set the speed. We'dl wire up logic gates and binary up/down counter chips directly to banana jacks on the front pannel. Everything was of course square waves. You'd patch up a logic circuit almost like you'd patch an analog synths only there was no audio or control sigs, everything was just a digital signal.
The shift registers were our favorite chips because we could make canons. Our shift registers were only digital, that is to say they would shift just one bit along the chain. We also used modulo N divider chips to generate melodies, as they would divide a frequency by whatever binary input was provided on their inputs. The shift register would have a pattern of walking ones that would be connected to the Modular N Dividers, in whatever order you wanted. This was a nice melody maker.
These systems we usually quadraphonic, but there wasn't much correlation between what was coming out of each speaker, except for canons made with shift registers.
I found playing around with these home made synths, we called them Lunettas, more fun than playing the Moog Modular system.
So, us Lunetta makers know synths that have only logic modules, no fancy oscillators, envelope generators, filters etc. Building Lunettas was how I got hooked into electronics which eventually got me into the profession. At my interview at Bell Labs a few years later, I told the engineers about my Lunetta experience and they hired me. They were crazy too, I guess. |
