Wavetable instruments use multisamples to map multiple samples at defined
pitches across the keyboard. If these multisamples are mistuned relative to
each other by up to 1 cent, it doesn't matter how accurate your tuning table
is, you won't be able to retune the multisamples to correct the errors
unless your tuning table is specific to each multisample. Now samplers
don't have this problem as they all allow you to fine tune the pitch of each
multisample. Most wavetable synthesizers lack this ability.

I know the main OS software engineer inside one of the keyboard companies
and he was receptive to upgrading some microtuning features. He will be
getting a copy of the wishlist. Will he implement all suggestions? I doubt
it, but every little bit helps. It also helps to have some pressure from
outside so the individuals can justify these features to their marketing
groups and management.

While I agree that tuning is not currently a priority for manufacturers, I
disagree that it never can be. Microtuning was on the marketing features
list for one proposed high end instrument at this company. That request was
put in there by marketing, not engineering. We are making headway, as slow
as it may seem.
