so i'm wanting to take this demo song, and add some extra instruments to it so it feels more complete, but the issue is I can't find the exact BPM, i'm using LMMS which only allows for whole number BPM, so i've been trying to get the songs BPM to be a perfect number, I know that for most of the song it's in a 77-79 BPM range, but I don't what the actual BPM is, if anyone knows how to fix this, it would be really helpful
