I'm just starting to dig in an learn the GPO software. I'm reading in the manual where it's describing the "options" button and I see items such as "Master Tune", "Auto convert samples to 32bit", "Lock Memory", "Library directory", etc.
I see all those options fine in my GUI...but on the next page it continues with "DFD Options", "Preload Buffer Size", "Voice Buffer Size", "Bypass the Disk Cache", "Mem. Total" etc. I cannot find these options anywhere within my GUI.
You are missing a long gone update from Oct. 2004, that installed the DFD extension. This doesn't seem to be a part of the 22.214.171.124 update. GPO KP1 is designed to load into RAM and you don't really gain much from using DFD streaming.
If you want to use DFD streaming you should instead update to GPO KP2.2.2 + KP2.2.3 (both updates are needed).
