Very easy and predictable for gurus , in Pa4X Next OS , korgPa gave users the benefit to stream from disk custom samplesKorg actually did something insane with the PA4x (in a good way); when it launched it only had 400mb flash ram
for fist time in PaSeries , so actually 400 Mb of DDR2 Ram (not flash ram) space was again used but only for preloading
custom samples that are by definition 10 times smaller than dropping the whole samples in Ram , so the actual smart
question should be , why only 1,5 Gb of custom samples and not 400 x 10 = 4Gb !
The reason I did this topic is that advanced users can conclude the unspoken architecture and real contents of Pa5X resources.
DFD method , direct streaming from disk is used in VST before 2000 where a sample library of 50Gb could be loaded in
your DAW without the need of a relative Ram of 50 GB but instead in 4 Gb only Ram space , dropping only the first portion
of samples in Ram and then read the rest from very slow HD/SSD media that can't be used as the required speed is 100 times
slower than speed of ECL Ram and this is the rule of function in all factory samples in workstations and arrangers
at least after 2008.
Users samples streaming from disk method had been applied in Oasys/Kronos workstations , and most of you are not aware
that since Korg Pa3X I can confirm , all factory samples are using the streaming from disk method due to save expensive
ECL Ram size , and since Pa4X Next and then , this DFD method is also used for custom samples and the difference from DFD
of Kronos/Nautilus is that Pa4X/Pa5X use internal flash memory as disk instead of external SSD as in Kronos.
The same DFD method is also used in all Yamaha keyboards factory samples for over 15 years.
Hpe this helps
