Sometimes, scrolling through factory Programs / Presets just won’t do it. You need to dive in, and tweak a Preset to your own liking, or particular application. BlackHole, ModEchoVerb, and especially the new WormHole algorithm are tailor-made for dense, thick, & huge. In fact, most any H90 Reverb can be adjusted to the same huge characteristics.
It’s been a while since I’ve heard examples of the Helix / Line6 Legacy Particle Verbs. As I recall, getting the initial ‘bloom” might take some fine-tuning to recreate. Be happy to help with some parameter adjustments later on.
In the meantime, take a WormHole preset. Any one. Crank up most of the parameters to maximum. Maybe Mix, PreDelay, Stability, & Stability Rate to midpoint; just to get a feel for it. Don’t be too concerned about any of the Warp parameters yet: that’s the advanced approach. Dial around one of the other parameters one at a time. See what you think.
