I've uploaded a couple of non-guitar sounds that you can play with just your guitar and Kemper.
Both sounds are designed to respond to your touch - so, experiment with different volume control settings on your guitar, and fingerpick, strum, etc. Hammer-ons are really effective with these patches.
VowelCelloDooSynth - when you play on the low strings, it sounds "cellish". It takes on a vocal synth sound as you go a bit higher. You can get both sounds at the same time, with hand dynamics in chords.

Vowelotron2 - the sound of your "singers" is controlled by your touch.
