garysjo: My latest quandary is to get recycle and logic running at the same time. I'm using 4.8. I assign recycle to say outputs 15 & 16 of the hammerfall, then delete those outputs from the logic environment. I get audio inb Logic, then go to recycle and get audio there. The problem is when I go back to Logic, I get no sound. I have to re-boot Logic. Any ideas?? pan: Try the option "release audio in background" (or similar) this did not work for me on Mac, but might work in your setup. So I selected "release audio in background when stopped" to no avail. Still have to re-boot Logic after returning from Recycle. On the contrary, I can have Cool Edit, Acid and Recycle all up and go back in forth from either and always get sound. Again, I am selecting two Hammerfall outputs per audio app. In Logic I do not have output objects assigned to the any of the outputs I'm using with Recycle. AArgh! Any ideas?
