ESPSYNTH86 doing R2D2 stuff |
|
|
The audio comes directly from the mic Phone, so excuse the quality. Live it sounds way clearer and crispier
It´s a generative patch doing kind of R2D2 sounds from some wavetable oscillators, FMs by wavetable LFOs and a semiimplementation of the karplus strong algorithm.
The hardware is a wemos d1 mini, trought a 4051 multiplexer and running the fantastic ESPSYNTH86 software by Budi Prakosa:

Thanks Phobos!!
It´s basically a bunch of wavetable oscillators and LFOs modulating each other in the middle of a karplus strong feedback path. This is just a patch in a infinity of possible ones. You just define the patch here, ala reaktor:
https://esptiny86.github.io/espnode86/
And that produces a patch code that you upload via usb to the synth. So basically is a mini reaktor in hardware. The hardware costs something like 5-6USD in components and then the possibilities are endless. The brains under all this development is Budi Prakosa, so all merit goes to him.
In my implementation Im using all the pins of the 4051, is just that I don´t know how to use the kicad yet. So people, take the shema as a reference only |

karplus strong is highly on my todolist when espsynth came into mind!
you can try svg2shenzhen to create pcb design easily and ready to be manufactured https://github.com/badgeek/svg2shenzhen |

Welcome to the forum, Budi!
Yeah, I would love to do an eurorack version of the pcb with a cool design, but Im still learning kicad. It´s a pity cause I have the design crystal clear in my mind but the footprints and library stuff of Kicad drives me craaazy!. |
