Question

is there a way that i can save my fx plugins and vst instrument as one so i can load them back up when am ready to use them back as one preset. so can use that sound that i have created sometime back.

Answer 1

I think this is what studio Ones Preset feature is supposed to do.
Try and look in the manuaæ in this section: Mixing > Effects Signal Routing - and read under "Navigating Effects Presets" and fwd on that page.

You can also create Studio One Multiinstruments.
