System 80 850

The System 80 850 is an all-analog module comprised of four sections: a voltage-controlled LFO, sample & hold, noise source, and slew limiter. The sample & hold is essentially the heart of the module, as the entire section is normalized to the LFO outputs and Pink Noise. Additionally, its output is normalized to the slew limiter's input so that an adequate amount of slew can be dialed in to the S&H. What's more, the S&H's clock can be configured as a triangle-shape LFO. Conversely, the primary LFO section consists of a delay circuit that can be triggered via rising pulse and features selectable sine, triangle, ramp, and square outs.

System 80 JOVE VCF and 850 Modulation Source
This video shows the System 80 850 modulation source and JOVE filter eurorack modules together. The JOVE is a filter based on the Roland Jupiter-6 with 24db and 12db lowpass, bandpass and highpass modes. The 850 is a very useful modulation source including an LFO, sample and hold, noise generator and slew limiter.
