Hi
Is there anyone using the Boss GT-001 for their guitar sounds who could explain how to re amp the sound with the GT primary and secondary outputs when using Sonar Artist
Thanks

Here's a doc I did on this a while back.  It's done with Reaper, but translates easily enough

Hi Bob
Thanks for posting that.  I had just about worked it out today with the help of some searching on line but I had to guess a little. It's a really good guide that you've written. I don't know why Boss don't put a guide note with the GT as there's lots of posts on line with similar questions. 
Thanks again
