Description

Zampler//RX is an SFZ and REX-compatible sample workstation developed by Synapse Audio for Beat magazine. Built on the same quality algorithms behind Synapse Audio's acclaimed Dune synthesizer, it delivers professional-grade sample playback and sound design in a single plugin.

The engine supports multi-format samples at 8/16/24/32-bit depths, mono or stereo, at any sample rate from 44.1kHz to 384kHz. It accommodates up to 128 keyboard splits and 128 velocity splits per region, making it capable of loading highly detailed multi-sampled instruments.

Sound shaping is handled through multi-mode filters (lowpass, highpass, bandpass, bandstop) inherited from the Dune synthesizer, three LFOs with four waveform types, and three ADSR envelopes. The modulation matrix routes up to 12 sources to 31 destinations, turning even static samples into dynamic, evolving textures.

The built-in effects section includes tube saturation, dual equalizers, phaser, chorus, delay, and reverb. A 32-step sequencer with multiple playback modes and swing control adds rhythmic complexity directly within the plugin.

Despite its deep feature set, the plugin maintains remarkably low CPU usage, allowing multiple instances to run simultaneously without taxing system resources. Thousands of expansion sound banks are available through zamplersounds.com, providing a continuously growing library of ready-to-play instruments and loops.
