A multi-function modulation source

The 850 is a fully analog utility module that combines a voltage controlled LFO, Sample & Hold, Noise source, and a Slew Limiter. The S&H section is normalized to Pink Noise (random) or any of the outputs of the LFO without patching. The output of the S&H circuit is normalized to the Slew Limiter input, allowing slew to be added to the S&H signal. The internal clock driving the S&H doubles as an auxiliary triangle shape LFO. The main voltage controlled LFO features an adjustable delay circuit triggered by an external rising pulse, allowing a gradual increase in LFO amplitude after a reset pulse.
