Blip...

Funny thing is I almost put this shot up when I saw it on flickr a few minutes ago. Something told me to hold off and sure enough a post went up on Analog Industries. It turns out this is a side project of Chris Randall's (Chris of Analog Industries and Audio Damage).

"One of the roughly 8,000 projects I'm currently working on is a small synthesizer built almost entirely on an Arduino. The only external chips are the DAC and the opto-isolator for the MIDI input. It remains to be seen whether the Arduino will be fast enough to pull this off. I would like to make it a normal 1-osc subtractive synth, but Adam (who has far more experience with microcontrollers than I) says that the Atmega 16 (the Arduino's brain) isn't fast enough to do the real-time math necessary for a resonant filter." You can read about the project here.

HardSID 4U playing a Lotus theme

YouTube via Ogrim88. via Nusonica

"I am giving my brand new HardSID 4U a go, with the main theme from one of the Lotus games. The HardSID takes up to four SID-chips from the Commodore 64. Sounds freaking awesome! Audio is recorded directly from the HardSID 4U to my recording soundcard, E-MU 1820. There is two 6581-type SIDs and two 6582 (which sounds like the 8580)."
