Thanks for responding. On a number of midi controllers, you have the ability to scroll through the presets on the virtual instrument you’ve selected, and even pick out a type of sound. Say like I’m looking for a synth analog bass sound. There’s many controllers that will categorize them so you can click through the sounds and select them. Or say if you have A Native Instruments virtual instrument like Absynth selected, you can turn a knob and audition the presets until you find one you like. And then once it’s selected, you can adjust parameters like filter, attack, sustain etc by turning knobs on the keyboard itself with going back to the computer to do it.
