Never thought of it, until today. I was experimenting with buffers, ASIO setup, etc. in Sonar 8 Producer 64 bits. I kept having once in a while dropouts, hicks and clicks. I also noticed that with changing those SONAR buffers the "looks' of the audiofile bounced, differs everytime.
I am still wondering how that was possible, because the source has been that one same midi input. I ended up with looking at the "Option" menu in the KP2 player and just without any argument to support it, I raised all DFD streams to the max, including those under Expert Mode(number of voices is now 384).
A world of difference. Now all instruments were sounding a lot brighter, basses were basses, trumpets were trumpets and tubas didn't sound as flushed toilets anymore.
So, if you can try it... I won't give you any garantee nor any responsibility for any damage (as they always say in Software programs).... but it certainly is worth looking into it.
My two cents,
