I could swear this was discussed but I can’t find it.
Would it be a lot of change to do something like this, where preon is still randomly chosen, but the out.wav file is based on the same number file used?
Secondly, how about the same hum plays until off/on. So if multiple hums exist, a random hum gets chosen and looped until next off/on instead of randomized when file’s done playing.
I don’t have time at the moment to play with the code but maybe someone feels like tinkering?
