Hi I am getting this in the cmd prompt when LEDfx is running. Sometimes after this starts LEDfx will freeze, not sure if it is realted.

d:\anaconda\envs\ledfx\lib\site-packages\ledfx\effects\gradient.py:94: FutureWarning: arrays to stack must be passed as a "sequence" type such as list or tuple. Support for non-sequence iterables such as generators is deprecated as of NumPy 1.16 and will raise an error in the future.
  gradient = np.hstack(self._color_ease(len(ease_chunks[i]), *color_pairs[i]) for i in range(n_colors-1))

I have 5 devices added. The error pops up after an API call. I use API calls to change the preset at certain times during a song. This error seems to happen whenever I do an API call to change the preset. The api call is successful and the preset changes.

Ah, i am not familiar with the API so i can't help you with that sorry. 🐤
