I have a Helix Floor with FW 3.71.0 and HX Edit 3.70, I have been running these since release with no issue. Yesterday I booted the Helix and all the FX loop blocks stopped working, nothing changed from the previous day. As a test I used a known working guitar cable and just patched send and receive together, still no signal when the block is enabled, I can see signal meter to the receive input. Also tried reinstalling the 3.71.0 firmware but no luck. Anyone else ever seen this?
