Multisampling fast.
Loop perfectly.

No crossfade — the loop stays raw and transparent. Important: Flux is only for essentially static raw waveforms (sine, triangle, saw, pulse) where you want the true waveform to loop without smoothing. Even a little modulation or movement in the sound usually means Flux is no longer the right tool — use Helix or X-ray instead.

X-ray finds a loop region and smooths the seam with a crossfade instead of a hard cut, hiding small phase jumps that would click on a raw splice. It fits sustained, evolving material—pads, filtered sweeps—where the wave drifts between cycles. You set blend length: more milliseconds mean a gentler join but a slightly softer transient at the wrap. When Flux is too strict yet you still want clear time-domain behavior, X-ray is often the balanced next step.

Helix rebuilds continuity at the loop point—closer to re-synthesis than a plain edit—so repeats read as one steady sound without harsh comb-filter shimmer. As the strongest all-rounder it is especially strong on difficult, irregular, or stubborn material, yet it still handles simple tones cleanly when you want one dependable default. Easy Mode defaults to Helix because it stays reliable where Flux would struggle. When you are unsure which algorithm to try, Helix is still the sensible first choice.
