Gravity delay is a polyphonic bouncing ball midi delay
Set the initial time interval for the first bounce, set the gravity level & the final velocity value and your midi notes will bounce along!
There is also a knob to set the probability of midi notes triggering the device, and a momentary button for more hands-on control.
Gravity = 1.0 is roughly equivalent to a ping pong ball bouncing on earth.
v1.1 - The small knob is a randomization amount for the time value
