I would echo what @highway_rehab said above if you’re set on the sound that you’ve got with the vst you’re using. The plugin grabber can be a little confusing at first, but it does the task well when the settings are right for the type of sound you’re grabbing. Definitely check the auto-loop samples (crossfade) box. I’ve made some lovely seamless pads from vsts through the plugin grabber.
You could also check out the New Tool (2.8-3.1): Padsynth for generating pad samples that are seamless. There’s a learning curve, but this synth tool can make some great sounds with a little tinkering.
pads are also a good use case for single-cycle native synthesis, and these days I’ll usually just make my own from waves in the instrument editor.
If you’re a jungle producer, definitely check out @GroovinG’s videos if you haven’t already. lots of great renoise content oriented primarily around jungle/dnb. He even has a recent video on 90s style jungle pad techniques, even though this particular one is not totally renoise-centric…
