[sdiy] TC9400 and XR4151 in synths & other ramblings

[anthony]

I'm surprised that I don't see much use either of these chips: TC9400 or XR4151 in synth work. The commonsound atoner uses the 4151 and "The Modern Implement Company" mentions the TC9400 used in something called The Rube Goldberg Function Generator.

The Modern Implement Company page is a recent discovery of mine.

Very cool. This is the kind of thing I'm working on in my analog work because all of the regular stuff I have a VST plug-in for. Which is not to say I'm limiting myself to that. Having a number of VST plug-ins to test different things to implement in the analog domain is very handy. And very fun. And there are tons of free plug-ins an even a few free hosts. I use tobyBear for my test bed. It only supports one plug-in at a time but there's a plug-in that lets you plug in a bunch of plug-ins as one. 

Even though I write conventional (well I do use just tunings and quarter tones but I've come to accept that as normal) music I really love Edgard Varese and Iannis Xenakis so electronic noises and stochastic music are very interesting to me. I'm more interested in implementing stochastic music generation in the analog domain - mostly because it's easy in the digital domain but I'm not a very good programmer.

There are a lot of great examples of modules that have given me some great ideas that I don't think I would have ever thought of before - like the things on the aforementioned page and Wiard's Woggle Bug. Ken Stone's site has several things that I think look great as well - like the Infinite Melody and even the V8 similator (which actually looks like it could be adapted into a nice ambient noise generator). I'm thinking of another level of stochastic control - that will be my first big contribution to the community.
