First of all, “modern” specs (especially from the vantage point of the idealistic, armchair tech designer) will never be a thing. It takes years to develop a piece of hardware like this, and component decisions must be made at the outset. You have to build around whatever tech is readily available at conception, and must commit to that, from the drawing board through to manufacturing, if the project is ever to come to fruition.
Second of all, it seems to me that if you were capable of out-programming these brilliant engineers, you’d have their jobs.
Thirdly, as a musician whose primary focus when buying and instrument is playing it, I can’t say that I’ve ever needed 2000 voices; but if I did, I’d simply use software.
To that end, software will always be a decade ahead of physical instruments, because it’s dynamic: i.e. when code is your only concern, the burden of advancing hardware falls on someone else, like Apple or IBM, and a thousand unbranded subsidiary companies.
Anyway, bravo ASM, for making a truly remarkable, robust, and ridiculously capable instrument for the touring musicians of the world.
Cheers!
