I'm certainly not complaining; I was just providing information to quell the rumours of things like improved signal routing.
Like I've said in another thread, it's exactly the same as when Boss replaced the RC-20 with the RC-20XL. A couple of years after releasing the original model, the memory (or, in the case of the 500x, the processor) is so much cheaper that you can release an improved model for the same price.
As I've also said elsewhere, those of us who already own a 500 are not the target market at all; they're just keeping things fresh for new customers, which is fair enough.
Off the top of my head, I think the only time I've really had any problems with the DSP limit is when trying to use twin Bogners with delay and reverb. As I've been umming and ahhing about swapping the 500 for a Pro, I'd certainly be interested in trying twin Bogners on a 500x to see if it sounds as cool as it does in my head.
If it does, maybe that'll tip the balance and I'll get a ProX when it comes out.
