Ok, Korg has 32 Mb and PSR has 16 Mb. But, how many voices they have?

Because if Korg has a lot more voices than PSR, perhaps PSR 16 Mb will be similar to Korg 32 Mb respect to the question "how many Mb for each voice?"

It is the case with VA-3: a lot of voices (3.000) but only 8 Mb. Or also VA-5: it has a lot of Mb (48), but it has a lot of voices too (3000).

So, how many Mb is not the only question... It is necessary to know "for how many voices these Mb's are".

In this sense, which will be the best kb respect to relation between number of Mb and number of voices?
