Title: Multi-bus AU's and Logic
In chatting with the Logic engineers, we came to the realisation that one of the problems they are having to deal with are the incompatible versions of the AU Instruments...
The problem this causes is that if Logic wires things up the “correct” way – which it does in Logic 7, then these older AU’s cause noise to be generated on their alternate buses. (These are the AU’s that incorrectly assumed that the number of outputs in the AU implementation classes meant “number of channels” - when it actually means “number of buses”) - so these AU’s create 2 ouput buses (instead of 1 output of 2 channels)... Because the AU is doing nothing with this second bus, its completely random noise that is coming out. The fix is simple – just change the numOutputs argument in your constructor to 1!
As this problem means that noise is generated on the second bus it is a very unsatisfying user experience (to put it mildly), and causes ongoing problems as Logic tries to move over to support the valid multi-bus AU’s that are available. This is also a problem that auval cannot pick up on, as the AU essentially looks fine (and auval can’t determine of course if the produced audio is good or bad).
So, we need all of the AU’s that have been developed this way to be fixed. We’re compiling a list of the problematic AU’s (with their version numbers that we’ll be making available) - I’m hoping that most, if not all, of the developers of these AU’s are on this list and will fix these AU’s and make a fixed version available ASAP.
Thanks
Bill
