I have an odd thing in a preset with a tone match, and a volume block, doesnt happen all the time time, but sometimes when i load the patch, it thinks my volume block is linked, and then it will put the output volume to 0 and lock up the preset... so the preset has no output... if i remove the volume block it's ok. I have a bunch of other blocks with the volume block, and no issues, only the tonematch.
