Hi, with AW2 and LA Silver 3.6 this worked properly. Only with 4.0 there is no sound while monitoring. There are also sometimes messages popping up which say something like "error while synchronizing audio and midi". However I do not use any MIDI when bouncing my song. I even deleted all muted MIDI data, but it still happens. J. F. Kayo www.mp3.com/JFKayo
