Lets just say it is not designed for that. If you're not wedded to the EXS 24, you could use something that is multitimbral in a single instance, and thus need fewer instances. EXSP 24 perhaps? > - to get audio back into the main app you need something like > Wormhole et al which does not go without latency and CPU hit. Because OS X CoreAudio drivers are multi-client, you can hardware-cable SPDIF out to SPDIF in, or ADAT out to ADAT in, route your audio out of the slave to those outputs, and the master copy of Logic can use those inputs. No CPU hit and minimal latency, a couple of samples on my RME. > - both copies access the same preferences file (at times which you > know, like, when you open or close the app) and the XS key (at times > which you don't know, all bets are off here). The XS key does not seem to be a problem whenever I've tried it. And for preferences, last one to quit wins.
