Noise! Noise! Noise!

[autowitch]

Just some fun with melody generators, shift registers, ring mod and pitch tracking. Sort of taking everything and throwing it together to see if something interesting happens. I probably should have cut the length down a bit...

Super build there .

That's alien abduction music in my book!

Hi Autowitch.

I've only just got round to listening/watching these posts (I had to be in a patient mood because, as you say, they are quite long!). Really like some of the sounds that you're getting. I'm building a lunetta at the moment (I will post very soon - I keep saying that).

Hey Gary,

I'm looking forward to seeing what you are working on!



I used this thread for the pitch tracker. I used the 4049/4046 version (more specifically the breadboarded one in the middle of the thread).

The pitch tracker can vary pretty wildly depending on the manufacturer you use for the chips. I don't quite get the laser bloops that some people do, but I do get a nice texture of gurgles. I'm planning on building another one using a different source for the 4046 and seeing what happens.

I suspect that tweaking the caps will lead to some pretty dramatic changes in the behavior. (You must build a pitch tracker; I can't recommend it enough).



For the shift registers, I started with this:

I only have one bit hooked up. I wasn't sure how to seed the bits going into the shift register, so I added a push button going from hot to one of the legs of the XOR input. That effectively gives me a bit toggle that I can use to seed the shift register as it starts or to tweak it when it runs.

I think using an XNOR instead of an XOR may handle this problem on its own; but I've decided that I like the manual tweaking.

I made two outputs for the "random" bits. One is just like it's seen in the emSynth schematic. The other ANDs the bit with the clock; that would give a pulse output. This could be fun if combined with the drum circuits found here: http://electro-music.com/forum/topic-52786.html

The eventual plan is to create four of these using the various XOR connections in the emSynth version. That should provide a source for 4 bit random numbers that could be used for all sorts of things.
