HotSwitch resets can get flaky sometimes. When in Learn mode, I always swing far above & below the targeted value before dialing in the reset value. It seems to improve the success rate for wiping out the stored value. In other words:
- HotSwitch ON: See which of the ten parameters have already been programmed (if any). For example, MOD-LEVEL in the Hall algorithm is programmed to 50.
- HotSwitch OFF: Make note of the unswitched value of the same parameter. MOD-LEVEL = 25.
- HotSwitch Learn: Turn the MOD-LEVEL parameter to the extremes (100 … 0) before landing on the unswitched value (25). Press the CTRL key (or Mac equivalent) with the mouse action to help zoom in on exact values.
At that point, HotSwitch OFF & ON should be reset to the same parameter values (no HotSwitch programming). Occasionally, I’ll still see some kind of random HotSwitch action introduced, on a previously unaffected & untouched parameter. Those are hard to shake, but persistence pays here.
I’ve gotten into the habit of “auto-saving” presets as I program them. Then begin any expression pedal or HotSwitch programming as a final tweak. It’s easier to revert back to a previous version if any HotSwitch programming starts getting stubborn.
