I just posted the (not complicated but funny, because it just shouldn't be necessary) *actual* workaround in my last mail (it doesn't add any latency, btw.): -------------------------------------------------------------------------- The reason why you can't access multiple audio instruments at the same time is that Logic is switching them from "live" to "playback" mode when you select another track (buffer size for deselected instrument tracks is increased and they will only react once Logic is playing). To keep them in "live" mode you can just do the following: - Insert an "I/O" plugin - Open the UI of the I/O plugin and setup *any* in and out - Bypass the plugin Now just cable your incoming MIDI signal to those instruments and set up appropriate MIDI channels in their object parameter boxes and there you go. It's still making me wonder why there isn't such an option straight on the audio instrument objects themselves. Wasting one plugin slot just for another funny workaround doesn't look too professional... ----------------------------------------------------------------------- The original question to this answer was whether it's possible to use Logic as some sort of multitimbral sound module, but you can of course also use this method to layer virtual instruments. Just create a *plain* MIDI instrument and cable it to the audio instruments of your choice. Regards, Sascha
