There is a simple pattern in the Beatbox. I rendered to a 2 bar wav and loaded it into the loop editor and used glide and non - glide notes to manipulate the loop.
While you could also chop up the loop, which has it's own benefits, there are also sonic advantages to this form of manipulation.
Edit: hit the play button and while the song plays press and hold the "Start" button of the PCMSynth to open the loop editor and view how the loop is being manipulated.
Soon I'll upload some examples to explain exactly how the loop editor behaves in case it's not apparent.
Ok, so for shits and giggles I figured I would take the existing drum settings, duplicate them and replace the drum loop with a vocal "Ahh" sample to see how that would lock with the rhythm. A few tweaks and here's the results. Kinda cool.
P.S. it sounds better if you turn the channel 2 Distortion Drive setting to full in the FX section, gels better with the synth track

More tweaks and started to mix and match patterns at the end which also gives some cool results. Remember, this is just an example of riff farming, the evolution of a simple drum loop, it's not a song.

Add a simple drum track and things start to take shape.
Clearly no interest in what I'm doing here so no point in continuing or including Caustic files.
FWIW this is what the Caustic file sounded liked at this point:
