Anyplace to download EDM drum patterns and acid patterns in Caustic project / Song format?

I'm trying to wrap my head around the Beat box machine midi note triggers so I can try to download EDM rhythm patterns from other VST / DAWS. Google results say Caustic's Beat Box machine 8 drum samples are mapped C3 upwards, but I can't find for sure any documentation on this.

As a result, imported midi from reaper is not mapping correctly.

Secondly, is there any resources where I can download EDM / Acid techno Caustic projects from old days? I've only just discovered caustic and find it so intuitive for live performance (as a DJ)

Thanks for any pointers.
