Barely used, sounds great.The Tiptop Audio CP909 is a Eurorack-format analog drum module that precisely reproduces the hand clap sound from the classic Roland TR-909 drum machine. It features the original circuit design, which utilizes a triple-sawtooth envelope generator to control a VCA, fed by a primitive, 80s-style logic-based noise generator. Key Features and DescriptionAuthentic Circuitry:Replicates the original Roland TR-909 clap voice, often considered a crucial part of 909 sound.Trash Control: A unique, additional knob that allows for "trashing" or lowering the frequency of the internal noise generator, extending the sound spectrum beyond the original 909 into distorted territory.Built-in Pulse Shaper: Allows the module to be triggered by various signals, including gate/trigger, clock dividers, or other pulse sources.Accent Input: Features a dedicated accent input that accepts both CV and gate signals, allowing for dynamic control over the loudness and attack of the clap.High-Powered Output:Capable of producing hot signals, allowing it to easily drive other modules in a modular setup. Sweetwater +5Technical SpecificationsWidth: 4 HP.Depth: 36 mm.Power Usage: +12V/6mA, -12V/10mA.Inputs: Gate input (normalized to accent) and Accent input.Output: 1 x 1/8" (clap). Sweetwater +3The CP909 is part of Tiptop Audio's 909-series drum modules designed for high-performance analog drum sounds, including the ability to add "trash" to the analog noise source for unique sound creation.
