how do you bus 6 channels from reason into PT??

theres only a mix L & R available to bus into my protools system - is it possible to get more than 2 channels??

Yes, instead of creating the multi-channel version of the reason rewire 2 plug-in, create the multi-mono instance. then you can unlink the left and right side and select any of the mono "hardware" interface ports from reason. 1 and 2 (L/R) are the only ones that are specifically set as a stereo pair, that's why they're the only ones that show in the multichannel plug-in instance. Hope that helps.

Note that you must also adjust the routing on the back of reason so that you are not going into the reason mixer but instead into various channels on the hardware interface. Hope this helps, Joseph
