>>33128 isn't enough in my opinion, but it's standard because that's what you get with MIDI.
32bit audio is the standard now. You can go down to 24 if you want, it's fine for storage. It's not like I'm pushing 96kHz audio here. You could drop the 48kHz to 44.1kHz too.
>>34What about physical modeling? These are the numbers on sampling to support the claim that the K250 couldn't have been pure sampling. PM synthesis can sound pretty good but that's not at issue.
