Who can resist the charm of the SID chip? Who'd of thought twenty+ years later folks would still desire the sound of this archaic technology? Well, desire they do, and now with Odo's fantastic and amazing Uknown64, they can have those sounds, for free!

Part of the charm of the SID was hearing it syncopated and arpeggiated into layers of lowbit soundscapes, and Unknown64 knows this! The arpeggiation controls are through the roof; note rooting, octave definition, and range setting. Your oscillators have all the classic generators, as well as ADSR to define and enhance the timbre. With vibrato control, ring modulation, pitch LFO (and pitch inversion), distortion, panning, filtering (and filter inversion), plus glide triggering (and even more) you can truly get vintage SID sounds screaming out of this little plug with minimal effort. That is not to say though, that you couldn't spend hours tweaking Unknown64 just to explore it's vast sound creation ability.

I feel that Unknown64 is hands down the best SID emulation VST you can find, and it's FREE. That makes it a no-brainer for anyone looking for Sound Interface Device tracks for their song, or chiptunes in general. I'm sure even Robert Yannes himself would blush over this marvelous bitkit.

PS The GUI is genius.Read Review
