reFX Nexus — Mac download

The Clipper FX arrives where you'd least expect it — at the end of a signal chain that can also hold a reworked unison engine with up to 16 voices. That's the kind of instrument Nexus 5 is now. It still loads your existing NEXUS libraries, but the architecture underneath has shifted toward custom routing, multi-oscillator layering, and hands-on audio editing.

Browsing, layering, and custom sample editing inside the instrument

• Browsing and tweaking large preset libraries without leaving the instrument
• Layering samples with virtual analog, wavetable, granular, or FM oscillators in a single patch
• Editing audio directly — slice, loop, crossfade, and map custom samples
• Building custom modulation routings with visible source tracking in the depth rings
• Matching preset previews to host tempo, with a BPM override when you need it

Existing library required plus a learning curve beyond preset recall

• Requires existing NEXUS content — the plugin references the library, it doesn't ship with a full factory set
• Skin editor and advanced oscillator wrap modes mean a learning curve if you only need quick preset recall
• Architecture supports both Intel and Apple Silicon, but the macOS floor is 10.15 Catalina

Unison overhaul removes phase smear across 16 stacked voices

Version 5.5.12 tightens up three areas that used to feel scattered across the interface. The unison overhaul is the most audible change in day-to-day patch design. Up to 16 voices now stack without the phase smear older versions produced at high voice counts. Setting detune and stereo spread takes longer to dial in, but the result holds together in a mix instead of collapsing into a washy pad.

The Clipper effect sits in the effects section as a hard limiter for transient shaping. You can push a kick or pluck into it before the output stage and get a controlled top-end crack rather than digital clipping. The keyzone trigger for the Ducker also changes how sidechain-style movement works — you can now drive the ducker from a specific key range, which is useful when a preset has to respond to a bassline played in a particular octave.

On the SYS page, the BPM readout and override option remove the guesswork from tempo-synced patches. If the host tempo drifts or you're building a preset outside a DAW session, you can lock the internal tempo to a fixed value. The two oscillator wrap modes affect how wavetable and granular oscillators behave at the loop boundary, which matters when you load short, non-looping samples and want them to wrap cleanly instead of clicking at the endpoint.

BPM override breaks tempo‑matched previews

• Preset previews don't match the host tempo. Check the BPM override on the SYS page. If it's on, the preview ignores host sync. Turn it off or set it to the session tempo.
• Unison patches sound thin after updating
