you're welcome. i doublechecked my samp manual, and 2 channel surround is indeed LCRS (i.e. pro logic). i found a link to an lcrs encoder plugin: i can't seem to find a decoder plug, though. it's possible (the details aren't clear from the manual), that samp is only encoding, and there's no decode on their 2 channel surround bus. perhaps the encoder and a surround panning plugin such as this one would get you where you need to go? it's at least worth a shot, and both are free. put the lcrs plug on your master bus, and make sure you set up 6 inputs for it (click the 2 in/6 out, and just add the necessary input pairs). insert the panner on each channel as required, and set the number of channel outputs to 6 in IO. that should do the trick...it at least works, but i haven't used 2 channel surround in quite some time, so i'm not sure it will sound the same as you're used to... k
