It maybe not clear which note/step has which adjustments, even though it could be helpful, more informative and easier to navigate.
It could be useful to see which steps have some actions activated. For example, always red for those pads that have less than 100% of “play step” chance. If it’s technically possible to adjust brightness per pad, it could be the less bright, the less the chance or something. There could be global settings for such stuff to adjust the device for your taste (always white is also cool/minimalistic).
