Vaporizer 2

Overview

Vaporizer 2 is a synthesizer and sampler workstation for producers who want to build sounds as well as play samples. It is strongest for sound designers seeking a broad, free instrument; those who only need a dedicated sample-library player may prefer a more focused tool.

Its combination of wavetable editing, several synthesis methods and granular sampling gives it unusual range at no cost. The practical check is compatibility: make sure your computer meets its processor requirement and that your DAW supports a suitable plug-in format.

Key features

Synthesis and wavetable editing

Four independent alias-free wavetable oscillator banks, with up to 24-oscillator unison, make layered wavetable sounds a central strength. Additive, FM and subtractive synthesis broaden the palette, while the editor supports Bezier-curve drawing, cycle editing and imports in Serum and Icarus formats. That makes Vaporizer 2 a better fit for shaping and creating sounds than for users who simply want to load a library and play.

The included content comprises 780+ wavetables and single cycles and 410+ factory presets. These give users material to explore and starting points to adapt, without replacing the instrument’s deeper editing options.

Sampling and modulation

The sampler supports WAV, AIFF, OGG, MP3 and FLAC, with loop points, key tracking, granular mode and sample-to-wavetable resampling. It can therefore move between conventional sample playback and more transformative sound design. Maximum polyphony is 32 voices, and sample mapping is not supported, so it is not the right choice for workflows that depend on mapping samples across keys.

Modulation spans 25 sources and 220 destinations, with five MSEG envelopes and five LFOs. MPE support includes pitch bend, aftertouch, release velocity and timbre controls, giving expressive controllers a role in performance rather than limiting them to basic note input.

Pricing

Vaporizer 2 is free: its GPL-3.0 software is offered at no cost, with standalone and plug-in formats for macOS, Linux and Windows. The maker also promises lifelong free updates. Existing Vaporizer 1 licenses remain usable with Vaporizer 2, and existing licenses retain support after the software became open source. There is no paid tier or trial to weigh against the free version.

Platforms

Vaporizer 2 supports Windows, macOS and Linux. The README names VST2, VST3, AU, AAX, CLAP and LV2 plug-in formats, and a standalone version; the product page identifies standalone releases for macOS and Windows. Linux builds include LV2. The minimum requirement is 1 GB RAM and a CPU supporting AVX or SSE2, with Windows 8/10, macOS 10.13 or later, or Linux. Check the format your host accepts and the processor requirement before committing to a setup.

Who it's for

This suits producers who want synthesis, sampling and extensive modulation in one free workstation, especially those interested in editing wavetables or using MPE. It is less suitable for sample-mapping workflows or anyone whose system cannot meet the stated CPU requirement. No security or compliance certifications are stated by the maker.

Pros and cons

• Pro: Multiple synthesis methods, granular sampling and wavetable editing support sound creation well beyond basic sample playback.
• Pro: The large modulation system and MPE support offer substantial control for complex patches and expressive performance.
• Pro: GPL-3.0 licensing, a free update policy and support for existing licenses make the no-cost offer unusually durable.
• Con: The 32-voice polyphony ceiling and lack of sample mapping limit suitability for some sample-based arrangements.
• Con: A CPU must support AVX or SSE2, which may rule out older systems.

Alternatives

Sampler Software is the broader category to browse if you want to compare sampler-focused tools.

• sfizz is another free option if its Linux, macOS, Windows, web or API platform coverage better fits your setup.
• Decent Sampler is a free choice when you want to play sample libraries in DecentSampler format.
• TX16Wx Software Sampler offers a free sampler plug-in and a professional unrestricted license with custom pricing; choose it if that licensing structure suits you.
• Just a Sample is a free, open-source sampler for Windows, macOS and Linux if that focused option is a better match.
• LinuxSampler is another free option; commercial hardware or software use requires prior written permission.
• Momentum has a free app and plugin for slicing, editing and manipulating WAV and AIFF audio, with a Pro plan at custom pricing.
• Source-to-Image is a free, open-source toolkit if that is the kind of tool you need instead.
• Subsample is another free option if you are considering a sampler alternative.

Verdict

Choose Vaporizer 2 if you want a free, open-source instrument that combines synthesis, editable wavetables, granular sampling and deep modulation. Its breadth and continuing free updates are compelling; look elsewhere if you need sample mapping, more than 32 voices, or a system without AVX or SSE2 support.
