Zampler RX
Zampler // RX
Zampler // RX is a high-performance sample workstation developed by Beat in collaboration with Synapse Audio, designed to deliver professional-grade sampling, modulation, and sound shaping in a free VST and AU plugin.
Built to compete with full commercial samplers, it combines flexible sample playback, deep modulation, and high-quality DSP into a streamlined but powerful instrument.
System Requirements:
- 32-bit
- 64-bit
- VST 3 / AU
- Windows
Professional Sampling Engine with Modern Modulation
At its core, Zampler // RX is a fully featured sample playback instrument built around SFZ and REX compatibility. The SFZ format allows detailed multisample construction with extensive keyboard and velocity splitting, making Zampler well suited for realistic instruments, drum kits, and complex layered patches. Support for samples across all common bit depths and sample rates ensures compatibility with both modern and legacy libraries.
Sound shaping is handled by a comprehensive synthesis section featuring multimode filters with low-pass, high-pass, band-pass, band-reject, and hybrid configurations.
These are supported by three ADSR envelopes, three LFOs, and a flexible modulation matrix, allowing producers to animate parameters dynamically and create movement far beyond static sample playback.
Effects, Sequencing, and High-End DSP
Zampler // RX goes further than most free samplers by including a full effects suite directly within the instrument. Tube saturation, dual EQs, phaser, chorus, delay, and reverb are available per patch, enabling complete sound design without external processing.
The integrated step sequencer adds rhythmic modulation capabilities, making it particularly effective for evolving textures, gated patterns, and complex tonal motion.
Under the hood, Zampler // RX uses DSP algorithms developed by Synapse Audio, the creators of the DUNE synthesizer. This gives the instrument a polished, high-quality sound character that stands up well in professional mixes.
The included factory content, curated from Loopmasters libraries, provides a solid starting point for electronic, dance, and drum-focused productions, with optional expansion packs available for users who want to extend the platform further.

FAQ
Its support for up to 128 key splits and 128 velocity layers via the SFZ format allows detailed multisampled instruments with realistic dynamic response.
Yes. The modulation matrix, step sequencer, and filter architecture allow extensive parameter movement, making it effective for evolving pads, rhythmic textures, and synthetic sounds.
The sequencer can modulate parameters over time, enabling animated filter movement, rhythmic volume shaping, or stepped tonal changes within sampled sounds.
It supports 64-bit VST and AU formats on both Windows and macOS, integrates cleanly into contemporary DAWs, and supports high sample rates.
Electronic dance music producers, sound designers, and composers who want deep sampling control without committing to a paid sampler will get the most out of it.
