DA-80 is a 4 oscillator, 8 voice analog synthesizer with a modulation matrix.

The DA stands for Dirty Analog. Sonically DA-80 can produce analog style sounds similar to Oberheim and Sequential Circuits classics.

The concept was to add noise to the oscillators right at the start.

Let the noise vary from a random undulation to straight pink noise. Compress the wave shape just a little then pass it through a selection of filters that vary from polite to unruly. Offer lots of modulation sources and destinations.
