I have also tested with the Boss BR-80 and GT-001 and this still seems to work well for me, so no obvious issues have arisen from making this change. I did also try the Boss JS-8. This works in Ardour, but capture from command line using arecord results in a file of silence. I'll do some more digging into this one. Regards, Keith
