One thing stands in between LMMS's triple oscillator being superior to FL's. That is the pitch envelope. I know that probably isn't part of the triple oscillator, really just part of the plugin host, but either way it would be a HUGE improvemnt and a real first for LMMS.
Just want to say I second the motion. Hate to bump, but I figure it's better than creating my own thread for the same thing. ;)
