iI've done some soundsynthesis with PIC Micrcontroller (yeah 8bit style) two synthesis forms based on chaos theory (celular automata and a fraktal (sirpinsky triangle) ) http://etecnic.fh-pforzheim.de/~catweazle/F-Synth/ And ...
I just finished the hard- and software framework. Both devices are still under development.
The Fraktal/CellilarAutomata Synth ... is available soon. The PCB is designed and I will etch some soon. The algorithms should be expanded a bit more before I can give it away. I could send interested people the pcb (soldered or only etched pcb), the pcb would be self etched (not professional industry PCB). You only have to solder some pots and switches on the PCB and have fun. (and the best: you can bend it then) The Software is stored in the Mikrocontroller, so for software updates the controller can be removed and send back for doing the software update. I don't have the time to sell it professional.
The LoopSampler ... needs some more time. I have to develop a human user interface first, I control it via a PC software (written in VisualBasic) so its not in release state yet. The hardware for the looper will be much more expensive. A lot of ideas to implement... If you have any suggestens for looping algorithms or ideas what could be done with a loop - let me know
I keep you informed about the projects and availabe pcbs
I've uploaded two new soundsamples for the "FractalSynth"
Recorded directly from the device, the audio output has an wide frequency spectrum from deep to high pitched notes, perfect for use with eq and filters (Korg, MB33
the audio samples shows only a little of the different sounds produced by the synth, little changes of the pots change sequence and tone often dramatic
