I just got the HX from Sweetwater yesterday.
A couple of questions:
1) One buggy item- after exploring the HX for a while, when I change a stompbox effect to a different model with the "big knob" , the effect keeps changing back to the original. If I reboot the HX, then the effect change will stick as it should.
2) I can't figure out how to save a stompbox configuration as a scene, like I can do on the M 9
