Neural Pattern Generator Pt. 1

"Cos I'm too lazy to program sequencers, I mean come on pushing buttons & working out what "sounds good" is hard work, I figured an easier way to do it is to let some binary equations do the decision making for me, that way if the result is crap I can blame the machines... right?

Anyway. The 4089 is a 4 bit digital rate multipler that provides an output pulse rate that is the clock-input-pulse rate multiplied by 1/16 times the binary input.... Its an old chip that isn't as easy to get as many of other 4000 friends, mostly because these days I think sane people use PICs to "perform arithmetic operations"

I'm sure a tiny amount of code could do what I'm doing in this vid, but, I only use computers to look at pictures of other peoples synths ;-P

The module in the middle is the Pattern Gnerator, the four switches set the binary input number & it has a clock & clear input. The other two modules are the Clock Divider (D)Mux on the right & the Varilogic II on the left."

Neural Pattern Generator Pt. 2


"Same basic set-up, but now the Pattern Generator is getting a Clear pulse from the 512 division of the main clock. A little bit of Long Division always helps.

I don't alter any of the logic or clock settings this time, just the sound generators & modifiers.

After I've built the "Odd" version of the mux I'm going to do another pattern generator but with logic inputs instead of switches :-D

As usual, sorry about the damned bird noises!!! I swear I don't even notice them at the time, the mic in this cam. appears to be optimized for 'sunnyday chirping' frequencies!"
