I was messing around resampling a pcmsynth preset sound when it occured to me that I could also sample from a drum loop and slice the loop using the start/end feature in the pcmsynth. Here's how I did it:
1) Create a 1 bar drum loop in a beatbox.
2) Add the loop into the main mixer as 1 bar then export it as a wav file and save it where you can find it.
3) Create an empty pcmsynth and long press the SAMPLE button. Find your drum loop that you just sampled and load it in sample 1. Now here is the tedious part, you need to set where you want each sample in the keyboard range. For this tutorial I initially used the default octave which starts at C4 and goes up to C5 to slice the sample into 8 parts.
4) Press the ROOT button and use the jog wheel to set the root of sample 1 to C4, now press the LOWKEY button and jogwheel it to C4 as well. Do the same for the HIGHKEY, set at C4. Now sample 1, your full 1 bar loop, is set on the C4 key. Next long press the END button and drag the end to the nearest transient. (I used a simple 4 on the floor beat to make seeing the transients a bit easier). Now your sample should only play the first part of the sample.
5)Repeat step 4 for the remaining 7 keys, setting the same sample on each ascending key until you get to C5. During each sample placement change where in the sample to slice it by using the START and END buttons. Essentially the sample is being sliced into 8 sections. You can slice more or less depending what you want.
Below is the caustic file for reference on what was done. There is a little automation in end to show a little variation. Keep in mind there are many ways to do this, adding more or less slices/keys etc...
The beatbox machine in the file is the original drums that were sampled from.
