BONG is a conga built from synthesis instead of samples. TUNE covers 70 to 340 Hz — tumba territory at the left of the knob, quinto at the right — and V/OCT moves the register per note, so one instance plays the whole drum family across a pattern.

SLAP is the hand on the skin: the attack transient that separates a muted finger hit from an open slap, independent of the body. DECAY sets how long the shell rings after the hit, and LEVEL trims the output. A gate fires it, every knob takes CV, and per-hit variation in tune, slap, and decay is what makes a static pattern sound played instead of programmed.

Designed and built by Ben Davis for Voltage Modular.
