Happy Holidays all! I'm not sure about "development costs being high." When I look at products like the FP-E50, the core arranger functions are all carried over from prior models like the FP-80 (and frankly very similar to the BK-9.) I suppose when one set of chips, displays, etc., goes out of production the engineers have to adapt the functionality to the new hardware. But that can't cost nearly as much as developing the arranger functionality originally did circa early-1990s.

I'm not surprised that the Pa5X is a "hot mess of bugs" because Korg were very ambitious about introducing new things. I perceive this to be the case with Ketron too. Only Yamaha, which is very conservative about introducing new features, seem to be pretty reliable from initial release.

All this to say, I think if Roland's management perceived a profit opportunity, they COULD release another MOTL arranger, because the foundation still exists and is evident in their other products.
