Pffff.. That's a relief! They broke a lot of things with the new upgrade, but at least I can still render my old files. Saying that, I'm still really pleased with the new renderer: You said that you knew the notes, but you can't make the sounds. Well I think it's just a way of finding the keys (or buttons ) and knowing how to use them.

But I can understand how feel: I'm a guitarist and I also had some organ lessons. But it feels completely different! your hands are in the wrong way!

To keep this anology, I think firefly and superfly are more like a piano and an organ: they sounds different and have a different ways to play, but they both have a keyboard.

-How can you improve things when you don't make mistakes?
