This patch uses the black 
channel to speed up and 
slow down the red channel. 
The black Div/Mult (

determines how quickly the 
red channel changes from 
fast to slow and back. The 
black PW  (

) determines 

how long it's fast vs. how 
long it's slow. The red 
Div/Mult (

) determines 

the slow speed, and the CV 
attenuverter (

determines the fast speed. 
After patching, we should 
hear bongos speeding up 
and slowing down and a 
kick whenever the bongos 
change tempo.

First, tap in a tempo. Plug Tap Out to trigger a "snare" or metronome.

Set red Div/Mult to anywhere between = and x3. Patch red INV OUT to trigger a "bongo" sound.

Set black Div/Mult to anywhere between /5 and /2. Patch black INV OUT to trigger a "kick" sound.
Patch black OUT to red Div/Mult CV.

Flip the black Mode Switch to the left to start. Try it later to the right, especially if black Gate PW is not centered.

Adjust red Div/Mult CV attenuverter knob slightly to the right. Hear how the red channel goes fast/slow? The amount it 

goes faster will increase as you turn this knob to the right.

 Adjust black Gate PW. To the left, the red channel will spend more time being slow. To the right, it'll spend more time 

being fast.

Set red Mode Switch to the left or right. Try both and listen for the difference (more hits to the right). Adjust red PW/Delay 

if you want to play with a timing offset

Now let's add some phase-shifting hi-hats. The blue channel is set to shuffle mode, and Trig Delay is modulated by a slow 
LFO or envelope, making the shuffle amount change over time. The green channel is set to a slow rate and should reset, 
ping, or trigger the external LFO/envelope.

First, patch blue INV OUT to trigger your "hi-hat" sound.

Set blue Div/Mult between = and x3. This is the base rate of the hats.
Flip blue Mode Switch right (shuffle).
Set blue Trig Delay (big knob) to about 10%. Play with the setting and hear how the shuffle pattern changes.
Set blue Trig Delay attenuverter to 100%. Try setting it lower for a more subtle phase modulation.
Set green Div/Mult to /16 or /32. Run Green OUT to ping or trigger a PEG or QPLFO, and run the output of that into the 

Blue CV jack. 

Optionally, instead of 

you can run any slow LFO into the Blue CV jack. Then the Green channel can be used for a 

different rhythm.
