Hey Marshall!
Super glad you enjoy Enrage!
There are currently not really sample features within Enrage. You can misuse the IR reverb as some kind of sample player, but that comes with a relatively high CPU cost. With modulated Grain Delay you can come close to you example, but that again is not the most straight forward way.
We are running into some limitation within how we set up Enrage under the hood and are working on Enrage 2.0. This will included much more sample possibilities and other wicked stuff, but we are rewriting everything from scratch, most importantly the whole architecture / infrastructure (so that we also can support Ambisonic and Surround natively). This is a major undertaking and will unfortunately still take some time - so not helpful right now.
Cheers,
Axel
