I have noticed many of songs won’t release when I load a new song. I’m fairly certain it has to do with a plugin I bought a few years ago called PSP Nitro. Got it for 9 bucks. Renoise will freeze and I usually have to force quit. I sometimes get an alert box that says psp nitro crashed after I quit Renoise. I probably should have posted this a year ago but I don’t use this plugin as much as I use to.
