Example Patch #2: Juke Rhythm

This patch makes a traditional Juke or Trap beat pattern. There are many variations of this beat, but this is a versatile starting 
point. 

Tap a tempo, or run a master clock into Red CLK IN.

Kick:

Turn Red Div/Mult to /3. Run the Red main OUT to trigger a "kick" and/or a low "conga".

Turn Black Div/Mult to /8. 
Patch Black OUT to Red Reset. The Juke kick comes from a /8 reseting a /3.

Hats:

Turn Blue Div/Mult to /2 or "=". Run the Blue QCD OUT to trigger your "hi-hats".

Flip Red Mode Switch to center (Inverted Gate mode).
Patch Red INV OUT to Blue Div/Mult CV. The Hats should be shifting tempo with the kick.
Adjust Blue Div/Mult CV attenuator carefully to get a good hats pattern. Try just a hair to the right of center.
Adjust the Red Gate PW, listening to how it changes the hats pattern. 

Kick/conga pitch:

Turn Green Div/Mult to /32. Run the Green OUT to your kick drum patch to modulate the pitch every 4 bars.

Hint: Really you might want to run Green OUT into an RCD or another QCD, and use one of those outputs to modulate pitch. 
This gives you more flexibility since the Green channel will also be tied to the Clap sound.

Flip Green Mode Switch to the right (shuffle)
Turn Green Trig Delay to 50%. Run INV OUT to trigger your clap sound.

You still have two INV OUT jacks not being used! Try patching them into other drum modulation points, or controlling an LFO 
that sweeps some other parameter of the QCD... 
Also, to add some spasticness, try patching the Blue INV OUT into the blue Reset jack. Adjust Blue Gate PW/Trig Delay to 
control density.
Next, with a second QCD, RCD, and/or SCM, you can slowly change some of the QCD's parameters to create an evolving 
beat. Just add a sampler, one vocal sample, and some footwork!
