Features

• The primary analog VCO produces classic 909-style sinusoidal bass drums but can also be switched to generate a square wave bass drum.
• The PITCH of the VCO spans several octaves, from about 30Hz to 240Hz, and can be modulated with voltage control.
• A novel PITCH DECAY circuit lets you adjust the duration and AMOUNT of the pitch-modulation envelope applied to the bass drum, from short blips to exaggerated tom-like sweeps.
• The AMPLITUDE DECAY allows you to adjust the length of the bass drum, from short punchy kicks to massive booms. This parameter is voltage-controlled with a quick CV response time, letting you modulate the duration of your kicks per step.
• The CLICK generator controls the attack intensity of the BD9. A significant amount of circuitry creates this subtle punch at the start of the kick. The level of this effect is adjustable up to a dramatic extreme.
• A square wave sub-oscillator derived from the primary oscillator's pitch can be mixed in (manually and with voltage control) to the BD9. The effect can range from subtle depth to extreme timbre changes.
• The overall timbre of the BD9 varies with the DRIVE control from warm, analog bass drums at low settings to speaker-shattering overdriven sounds at high settings. Output levels are modular-level signals, unlike many classic line-level percussion devices.
