How can I load only some of the instruments data in the sf2?

[call7yobu]

When I load Sf2 into a Tx16wx software sampler, how can I load only some of the instruments data in the sf2 to make the software run more smoothly?
When I use sf2 with all instrument data of the sf2, the DAW software becomes slow when the auto-save function of the DAW software is activated.
I would like to know how to solve this problem, so please let me know.

Double click the sf file in the TX file browser. It will open as a file system. You can now select individual programs or samples and load into slots/regions. You can also preview-load/browse the presets and samples for selecting which sound you like without having to load it fully. (Enable preview. click a slot active, then click any preset in the SF2 to temporarily load it).
This is all in the manual btw.
