Glooper
This is a combination multi-unit looper and echo. The fundamental building block is a clocked looper that grabs a one clock loop. Eight of these are stacked and fired in succession from the external clock. Each looper has a probability of recording set by the density control. The output of the loopers is summed and fed to a master echo. The decay time for the master echo is set by the feedback control. A dry/wet mix control is also provided. In order to provide a sense of movement, the multi-looper/master echo module is duplicated for a stereo ouput. Recent improvements include a reset and a mono - stereo input switch (red is mono).
Various effects can be achieved depending on the clock rate, density and feedback settings. High clock rates produces a “granular” sort of effect and low rates are closer to a traditional looper.

Notes |
| clk |
0-1 clock signal |
clock for the unit - note that the glooper must be clocked to cycle the loops. Stopping the clock will result in a “frozen” output that can be interesting. |
| rs |
0-1 gate |
reset - resets the glooper and empties the loops (note: looper must be clocked in order to fully erase the loops) |
| r |
-1 to 1 audio |
right audio input - not used in mono mode |
| l/mono |
-1 to 1 audio |
left or mono audio input depending on toggle |

Notes |
| feedback |
sets the decay time of the master echoes |
Range is from 0 (no feedback) to 100% (no decay) |
| density |
sets the probability that a looper will record |
At 0 no recording will occur and at 100% the loopers will all record. Note that the random number generators for the left and right channels are separate so when density is less that 100% left and right channels will fire independently. There is a light for each channel within the knob that is on when that channel is recording. |
| mix |
sets the wet/dry mix |
