Processing stems with L2 in Logic

Hi, when I bought the L2 it was not able to process stems with it's sidechain feature. Has that been fixed yet?

Hi Chris,

Pro-L 2 is capable of stem processing using the side-chain function. However, there is a latency compensation bug in Logic which make it not possible to use stem processing. Basically the the side-chain input of Logic will be compensated for plug-in latency with the same amount that the channel itself will be compensated. This results in the side-chain signal arriving late in the plug-in, so there will an offset in time between the input and side-chain, resulting in processing being applied too late.

We have reported this issue multiple times with Apple, but as for as we know this has not been fixed.
