Tim Escobedo's PWM Thru Lunetta

[Draal]

Here's a sample of the pwm module destroying my guitar signal. Feedback is also possible while playing, which adds some variety to the stock lunetta sounds.

The guitar volume knob also affects the tone quite a bit; from lo fi scratches and blips at lower volumes to wilder, blow yer socks off sustain at max. Lots of experimenting to do, but I really like this addition to my machine.

Mic input also creates interesting sonic opportunities. Add a delay or your fave pedals and beat those kids with there loop noise pedals to a pulp.

I forgot to add the obvious: Yes, you can use whatever you have running through the PWM as a clock source for some things. I say "some" because I've only skimmed the surface in its capabilities. I have successfully used my mic and guitar as the clock source for the 4040 ic, which outputs have been connected to my 4051 cv gen and it definitely works.

Looking to test its clocking abilities with the melody gen as well as any counter. I expect some things may not clock as expected, causing glitches and what not. But hey, let's get back to the lab....

Update: Here's a guitar track using said instrument as a clock source for the 4040 ic. A few of the outs from the 4040 are going into my r/2r, then my vcf, then my vca, then out to amp. The longer I hold a note down, a longer sequence plays as well as a change in pitch when I change positions on the neck.

I can also change the length of the blips by adjusting my volume knob on the guitar. The goal here isn't to be perfectly in tune or traditional in ANY sense. I'm looking for twists in how we control our lunettas.

Second clip is me whistling into my NOS Turner Chief mic. It is also clocking the 4040 in the same setup. Replace my whistling with any wind intrument and you get the idea.

if you smooth out the signal by filtering a bit with a lowpass, to get rid of the unimportant higher harmonics, before the pwm module you can drive other modules more cleanly. its possible to get octave downs from your original signal, or with say a 'melody generator' to derive other ratios instead of octaves, say, 5ths and so on. and the obvious sequencing of patterns like you are doing.. having the guitar pwm'd be an oscillator to drive other functions.

then its possible to get trigger functions as well... trigger an env... GUITAR SYNTH!

Thank you for the tip . Hope to tweak it some time this week.
