PWM Plus 4040 Equals Fun with Octaves
Just a quick vid of my electric guitar going through the PWM from Tim Escobedo and then into a 4040. Connecting different outs will obviously give you different octaves up and down the neck. Shall be building a pedal version soon with some other mods for octave up.
Glitchy (so are the expensive pedals), and best with single note runs. Great Atari sounds to be had. Of course, you can connect a cheap keyboard or circuit bent toy this way and mess with it further.
Being more of a guitarist than a keyboard player (alright, I'm less inept at playing the guitar) I'll have to give this a go. I've already got the 4040 circuit set up, so it should be that difficult to try out. You say it's best for single note runs - I assume chords just sound like a load of noise (sometimes a good thing ). Is your octave up bit going to use a 4046? I've still only used it as a VCO so far.

With the 4046 patched in after the pwm or 4040, you'll hear what robot tyranny sounds like. I liked the simple add-on of the 4040 after the pwm best so far. I have also connected two different outs of the 4040 to a 4081 ic and it worked well in adding depth to the octave effect. Different gating ic's offer a similar mixing effect.
Another idea I'm experimenting with is adding the simple VCF circuit found deep in the archives here. I am tweaking a few fuzz pedals this weekend but I hope to record some more clips showing these ideas. Thanks for checking it out! _________________ Zontar Prevails!

Really Bad Demo!
Hi Draal.
After you mentioned VCFs, I thought I'd try it through my "Flightcase Synth" and it seems to have potential. At the moment, it is not always triggering properly and there are a lot of glitches (it's not all down to my guitar playing...) but I think with some tweaking, it should be useful.
I thought I'd put this bad example on now, as I'm on holiday next week, so I won't get much chance to improve upon it until I get back.
Anyway, here it is. I'm using the -2 octaves output, by the way.

That's really great! Hell, even the expensive "booteek" pedals mention that glitching is part of the "charm".
The honey-do list has been creeping its unruly head the past few days for much experimentation for me. I may still have a another clip running the guitar thru the lunetta ...have to check. _________________ Zontar Prevails!
When I get back next weekend, I'll have another look at it. I like the glitches, but you have to get used to playing it (hence it's a bit of a mess). If you don't hit a string with enough force, nothing happens! I think that I can fiddle with it to get more reliable results. That said, I was impressed with the sounds I was getting out of it - much better than putting the unprocesed guitar straight into the VCF.
