I have this same problem. I can record the FX pad data as parameter automation. However, when I play back, the FX pad does not read the recorded automation.
BUT, if I click and hold my mouse in the FX pad, the pad WILL read the recorded automation.
So there seems to be some problem with the pad reading the data. We know it works while holding the cursor clicked within the pad, but that is not always convenient
Thanks in advance for anything
