## Frequency (Hz)

The pitch of the drum note expressed in Hz. This tunes the "fundamental frequency" or "base note" of the sound.

## Decay (seconds)

Determines the length of the drum sound. Longer sounds can sound similar to a gong.

## Center frequency of noise (Hz)

The center frequency of the band-pass filter that is applied to the noise. Higher frequencies can sound as if small cymbals are vibrating with the drum stroke.

## Width of noise band (Hz)

The minimum width of the band-pass filter that is applied to the noise. Higher values can increase the impression of a gong sound.

## Amount of noise in mix (percent)

The amount of noise in the drum sound as a percentage of the mix. Values near maximum can sound like a gun shot if other controls are left at default values.

## Amplitude (0-1)

The peak amplitude of the generated sound.
