"Special Stage Systems has taken the SN76489AN chip that was the sound chip in many 80's video game machines and built a synthesizer voice around it with function generators, CV controls and presets. The Oscilliographic Block can create great 8-bit drum sounds and melody lines. It has two square wave voices and a noise voice with white and periodic noise types. There are 6 programmable function generators that can produce smooth or stepped waveforms. These function generators can be used like modulators, LFOs, envelopes or sequencers. 4 CV inputs can control pitch, amplitude and the speed of the function generators. The clock that runs the SN chip can even be adjusted to over or underclock for different pitch ranges. There is a 1V/octave scaling for playing the sounds in tune as well.
