Has anyone had issues with this on the OT? I thought it was a problem specific to the aalog boxes. LCD is a really mature, reliable technology, while OLED is still quite new uand untested in the long term. I’ve got/have had/have used a ton of equipment with 25-35 year old LCD displays hat were still fine, maybe slightly dim from time to time but even that has been pretty rare for me. They don’t really fail that often. I’ve literally never experienced one that was actually dead or damaged, although the DR-660 I have right now is kind of faded and has a poor viewing angle. But it’s 25 years old and judging by how weak the aftertouch sensitivity has gotten on some of the pads it saw a LOT of use. Even the MPC2000xl that was the center of my rig from 2010 until I got the OT last winter (and before me was being used by a guy who was making his entire living selling beats and used it so heavily that he was averaging 8 completed beats a day for long enough that he’d had to replace the pads,sensors and data slider because they’d all worn out under normal studio workload) has a screen that is still working perfectly after around 15 years, and that’s a piece of gear with a well known heat dissipation problem that specifically damages the LCD.
Personally I’d trust a mature technology that had a track record decades long and was nearing its end of life over a technology that had only been in wide use for a few years and still has plenty of industry-acknowledged flaws if reliability an longevity is important.
OLED looks great but personally I’m not interested in being an early adopter.
EDIT: BACKLIGHTS on LCD screens definitely get a bit dim over the years though, even when the screen itself is fine. I had a couple of early 90s Alesis rack units for a while that I got in a trade and ended up trading to someone else, and they were still perfectly usable but definitely not quite as bright as they were when they were new, judging from the brightness of other gear from the similar era.
