Slow preset change

Hi! Thanks for your reply! So, yes, im using gpio because i have many keyboards and i want to use it with diferent keyboards so i dont think using midi to change the presets its a good ideia... Normally i dont have heavy presets but just to give you a example: I sampled keyscape with 8 velocity layers, i know that 4 velocity layers jumping every 3 note its fine however i wanted this set to be as close as possible to the original. So every time that i change my preset and i pass thru this set i way around 4 seconds LOL. Im thinking about using a ssd, it probably will improve the speed. And aout the 0,1sec that i sugested is more like these: if i want this preset it will add a +0,1sec to load(in my opnion its just a little bit of time added), if i want to surf thru presets fast i would ebe pressing the buttons faster tahn 0,1sec (sometimes even keeping pressed) and samplerbox wouldnt be loading the sound that im passing throught, it would just pass trhough tha preset without even loading. Thats the ideia that i had, of course that it would be better if any time that you press the gpio button the process of loading the sound stops, but if i understood what you said, this is not an easy task.
