So... my techie son decided to do me a favour when I was out of town, and "updated" my Helix to 3.15 for me. Evidently he did the following:
updated the Line 6 Updater, then ran that which apparently updated the Helix to 3.15
THEN, he updated HX Edit and made a backup.
THEN, he did a factory reset on the Helix and after that restored the backup.
NOW there's a huge latency in the connection between the Helix and HX Edit...
ALSO a big delay in Helix when switching from one preset to another
not really sure what to do here / if I remove+trash HX Edit and do a new download, would I be able to use that to "re-update" the Helix FW ?
MANY thanks for any and all suggestions, insights etc !
(BTW, son had best of intentions, but it turns out he didn't READ the instructions... sigh.)
