I’ve been a registered renoise user for at least a couple of weeks and have been using render to .wav without any problems (almost:).
Anyway, I just downloaded and installed the latest version (1.5 beta1) from the members section, and I’m satisfied to the extent that I just can’t find the render button! Why isn’t it there? Have you changed its location?
EDIT: Duh, I found it… Didn’t have ‘Song’ checked in disk browser ;/ Sorry, problem solved. Carry on! Haha
