You can't connect Helix Rack directly to your Focusrite via USB. Audio cables, fine, and both units to your Mac/PC via separate USB cables, fine, but even if the Focusrite has USB hubs (not sure if it does), Helix won't support it.
1. Select an assigned block that's bypassed by touching the footswitch repeatedly (or selecting it with the joystick) and save the preset.
2. Select an assigned block that's on by touching the footswitch repeatedly (or selecting it with the joystick) and save the preset.
EDIT: audacityworks and Digital_Igloo are the same person, by the way.
The only Guitar Centers authorized to sell Helix (at least right now) are Platinum stores. IIRC, there aren't more than 15-20 Platinum GCs nationwide. Unfortunately, it's gonna be a while before anyone can just walk into any of the 200+ GCs and pick up Helix.
Very odd. Just one MIDI cable from your X3's out to Helix's MIDI in? Anything else in the chain? Is Helix connected to your computer via USB at the same time?
