Prok BD

Bass Drum

4 HP Eurorack module

BD is a morphing bass-drum module, spanning one-oscillator 808/909-style sounds through kicks built from four oscillators, two waveshapers, and a noise source.

Features

  • Four QUAD sound sets, each built from four corner patches, provide 16 preset patches per bank.
  • Real-time morphing modulates all synthesis-engine parameters rather than simply mixing four channels by volume.
  • Custom patches can be created with Prok Modular Control, copied to an SD card, and loaded instead of factory patches.

Controls & Jacks (11)

  • Y— Sets the Y coordinate of the morph position between patches in the current quad.
  • Y CV Input— Positive 0–5 V control-voltage input for the Y morph position.
  • X— Sets the X coordinate of the morph position between patches in the current quad.
  • Trigger Input— Triggers the sound on a rising edge.
  • Audio Output— Mono audio output.
  • X CV Input— Positive 0–5 V control-voltage input for the X morph position.
  • Trigger— Retriggers the drum sound.
  • Morph Position Top Left— Indicates the current morph position and flashes during quad selection; this is the upper-left square of the four-square display.
  • Morph Position Top Right— Indicates the current morph position and flashes during quad selection; this is the upper-right square of the four-square display.
  • Morph Position Bottom Left— Indicates the current morph position and flashes during quad selection; this is the lower-left square of the four-square display.
  • Morph Position Bottom Right— Indicates the current morph position and flashes during quad selection; this is the lower-right square of the four-square display.
