    The CP909 is an exact reproduction of the original analogue circuit and, with the addition of just one extra knob, 'trashing' the frequency of the internal noise generator, Tiptop have added greatly to the spectrum of sounds that can be generated without compromising the signature sound of the Roland TR-909.
    The CP909 clap effect is made by a special triple-saw envelope generator that controls the gain of a VCA. The sound source feeding into the VCA is made by a quasi-random logic based noise generator. Some might call it 'digital noise' though this term might be misleading in today's world of micro-controllers and sound samples. What really makes the noise generator is a ring of logic gates, primitive, but that's the sound of the 909 clap!
    The CP909 includes a high-powered output gain stage capable of producing hot signals. On the inputs, Tiptop have designed a dual-input pulse-shaper circuit so you can trigger the SD808 with Trigger/Gate signals from step sequencers, clock dividers or any other pulse/clock sources. This saves you the need to shape the pulses sent to the module and ensuring the same stable sound at its peak power, regardless of the differences in your pulse source.
    Based on the architecture of the 909, the Accent input is versatile and able to take in both CV and Gate signals for continuously changing dynamics. All these unique features make integrating this legendary sound generator into your modular synth easy.
