B-160 Bouncer (4HP)

B-160 Bouncer module for Eurorack / Doepfer A100 system.

From the top down:
Trigger input jack + LED
Encoder w. push switch
Rate knob
Flexibility coefficient knob + CV in jack
CV out jack
Trigger out jack

This is “jumping ball simulator”. Current ball position is displayed in the most left column. At trigger the ball can be dropped from the height or fired from the ground. Jumping rate and length of jumping is set by rate knob, flex coefficient knob and ending height on the display. The rate is fixed at moment of trigger and remains the same for the rest of current cycle until ball finaly ends on the ground.
Range of one initial jump is approx. 100ms to 1,8s if dropped and doubles to 200ms to 3,6s if fired from the ground. It means it simulates initial dropping from 5cm up to 15m.
With max. flex coefficient and lowest ending height set it can jump over 2 minutes alone.
Output trigger is 5V (w. adjustable width), output CV range is 0-5V and first jump after triggering goes through full range 0V>5V>0V if fired or 5V>0V if dropped.

There are 8 adjustable parameters on the display:

  • Dropped/fired w. disabled retrig (arrow), dropped/fired with enabled retrig during curent cycle (double arrow)
  • CV is based on position, velocity, inverted velocity or “one direction velocity”
  • output CV is continuous or CV is held at peak
  • CV quantization (without quantization or quantized in 16 scales, see table of scales on Q-010 page)
  • Initial trigger on/off (displayed as I.TRIG or TRIG)
  • Trigger width 1, 2, 5ms
  • Trig is generated at ground bouncing, on the peak or on both bounce + peak
  • Ending cycle height (0-9)


Width: 4TE/ 4HP/ 20mm
Depth: 50mm /2″ max.
Current: 30mA max.
Power cable included

Double check power connection before powering your system please.
„Red strip“ means -12V connector side in Eurorack standards.
In some power distribution systems connector key can be reverted.
In this case cut connector key and plug power connector right way (with respect to red strip) or use different power cable appropriate to your power system.
