Presets and Live? a few questions

First day with organelle. Very impressive and fun to use. Can someone walk me through how this would be used in a live setting with midi. How do presets work? Are there only presets for certain patches? And for the presets do you have to hit the encoder knob everytime? Trying to incorporate this in a band setting where i can just hit a button on my midi controller and it loads up my patch and preset and im good to go…Thanks
