Tiptop Audio BD909

BD909 is a kick drum generator that uses a clone of the Roland TR-909 circuit. Controls not found in the original are also added to create a kick that has a punch in the low to mid-low frequencies (BD808 is even closer to the low frequencies).

Attack, Decay, Tune Decay, Accent, Level In addition to the controls originally installed, Tune control, CV control with attenuator, and Tune attack have been added. In addition, the width of Tune Decay has been widened, and it is possible to find sweet spots with a different sound from the original 909. And then there's the distortion overloading the waveform and its CV control.

Starting with a classic 909 sound, you can use the additional features above to further change that sound to create a wider kick sound.
