SL73 Studio : Beautiful Hardware - Questionable Firmware.

I might be alone on this but I just wanted a High quality Midi Keyboard that felt close to a real piano. Essential features like mod wheel / pitch bend - potentially dials for macros (which this doesn't have fyi). I was really impressed with the build quality and the feel of the keys. It feels great, it's super high quality and I don't see anything breaking anytime soon (I've had it for over a year now). Now the thing that I don't like is the firmware. It's completely unintuitive. It seems like there's a lot of inbuilt sounds? But they load into 4 separate slots?? I have no idea, I can't make sense of it and don't want to. Instead of changing octaves being a simple button, you have to go into the settings. I now use it with Studio One and leave UA Luna only for mixing / tracking. It would glitch with Luna ALL the time. Randomly changing to "x soundback 456" or something random and becoming unresponsive. I would then have to turn it off and on again. It has worked fine with Studio One so far. Again, great physical quality. But I really don't like the inbuilt firmware.
