Thunder Overlay X/Y Issue

X and Y gestures don’t do anything. I’ve tried different presets and sliding my fingers up or down results in no change in timbre, etc. The current synths I’m using are Aalto and Serum—both are used in FL Studio. I’ve enabled MPE on both. I’ve patched Aalto multiple times so that it can register X and Y movements—for example, I’ve patched it so that y movement changes timbre. Absolutely nothing works. I’m sure I’m doing something wrong with the SenselApp. Either way, I’ve gotten pretty frustrated with this and would love some assistance.

Thanks.

EDIT: Never mind. I believe the problem is that FL studio isn’t capable of MPE
