IK Multimedia ReSing

Overview

IK Multimedia ReSing is a desktop application and plug-in for replacing vocal takes with modeled voices and transforming vocal or instrumental tracks. It suits producers who want voice conversion and custom model creation in a DAW or standalone workflow. Its appeal is the range of voice-shaping controls and local processing; the choice of license determines how many models and generations you get.

Key features

Voice transformation and custom models

Transpose, character, accent, dynamic range, and the ability to fuse two models give producers several ways to reshape a converted performance. Preview and built-in effects help refine the result within the same workflow. ReSing Modeler creates voice or instrument models locally, while the Unlimited Model Generation add-on removes the generation limit for ReSing and ReSing MAX owners. The included generation allowance is modest on the base license, so producers building many models should account for the extra purchase.

Model support covers English, Spanish, and Japanese. Japanese and Brazilian Portuguese voice packs add models and model-creation language support for those languages. IK says transformation runs on the user's computer, with an internet connection needed for authorization. The company says its voice datasets come from original recordings made with participating singers under agreements, rather than copyrighted songs, samples, or third-party material.

Doubling and DAW integration

The optional Doubling add-on generates vocal doubles, backing vocals, and stacks. Timing, detuning, stereo width, volume, and pan controls make it useful for building layered parts from a vocal, though it is an add-on rather than a stated inclusion in the plans below.

ARA2 mode is listed for Cubase 12 or later, Logic Pro X 10.4 or later on Intel, Studio One 4 or later, Nuendo 11 or later, and Reaper 5.97 or later. ReSing also runs as a standalone app. It supports Audio Units, VST 3, and AAX on macOS, and VST 3 and AAX on Windows. Minimum requirements are macOS 13.7 or newer or Windows 10 64-bit or newer, 8 GB RAM, and 9 GB of disk space. That excludes older systems and, on Windows, Audio Units.

Pricing

ReSing is freemium, with no free trial. The free tier costs nothing and includes 2 voices, 2 instruments, and 1 RVC import, with no model generation. It is a sensible way to explore the workflow, but its small model selection and lack of generation make it a limited option for ongoing custom-voice work.

ReSing costs $129.99, paid once as a one-time payment. It includes 10 voices, 10 instruments, 10 model generations, and limited imports. This is the core paid choice for producers who want to create some models without paying for the larger library and unlimited imports in MAX.

ReSing MAX costs $199.99, paid once as a one-time perpetual license. Its 25 voices, 25 instruments, 25 model generations, and unlimited imports suit users who expect to work with more models or import frequently. Unlimited Model Generation Add-on for ReSing costs $149.99, paid once and requires ReSing or ReSing MAX; it removes the generation-count limit, but does not replace the included libraries or change the stated import limits. A ReSing Session is a one-time purchase that gives access to a selected Showcase model for one month, activates on one device at a time, and does not renew automatically.

Platforms

ReSing runs on macOS and Windows, as a standalone application or plug-in. Check the listed operating system, memory, storage, DAW, and plug-in format requirements against your setup before buying, particularly if you rely on Intel-only Logic Pro support or Windows AU.

Who it's for

ReSing fits producers seeking modeled vocal replacement, vocal or instrument transformation, or locally created voice and instrument models. The free tier is suitable for a small-scale evaluation; ReSing is the more practical starting point for occasional model creation, while MAX makes more sense when a larger included selection and unlimited imports matter. Producers who need a broad generation allowance should compare the add-on cost with MAX before choosing.

It is less compelling for someone who only needs mastering or analysis tools: ReSing's central job is voice and track transformation, and the paid licenses are focused on model access and creation.

Pros and cons

• Pros: Multiple controls for shaping converted voices, including model fusion and dynamic range, give more scope than a simple voice swap.
• Pros: Local transformation and model creation keep audio processing on the computer, with authorization still requiring internet access.
• Pros: Standalone use, plug-in formats, and supported ARA2 workflows provide several ways to fit it into production.
• Cons: The free tier allows no model generation and only one RVC import, so it cannot establish whether a custom-model workflow suits you.
• Cons: ReSing's 10-generation allowance is finite; removing that limit costs another $149.99, paid once.
• Cons: System requirements are relatively specific, and Logic Pro X ARA2 support is limited to version 10.4 or later on Intel.

Alternatives

For a free, open-source mastering workflow, choose Matchering: it is available across Linux, macOS, Windows, self-hosted, and web, but its stated role is mastering rather than modeled voice transformation. For audio mastering with free and paid editions plus a free trial, consider WaveLab; its Elements 13 and Pro 13 prices are custom pricing, and LE is free.

Tunr is another free option, with a free key counted per machine and a stated allowance of three masters before a licence key; its listed output options include 16-bit and 24-bit. If you need a free real-time FFT spectrum analyzer plug-in, Voxengo SPAN serves that narrower purpose. On macOS, StudioZIO Mastering Suite is a free mastering suite for macOS 11 or later, with AU, VST3, AAX, and standalone formats.

TDR Limiter 6 GE costs €60, paid once for a personal or small-business license covering one user and up to five computers; consider it when you need a limiter rather than voice conversion. DSP-Quattro is a macOS audio application with a free trial, and its new license is listed at $99 a month. Acustica Audio Erin Studio is a paid macOS and Windows suite with two EQs and two compressors, listed at €45, paid once; choose it for those processing tools rather than ReSing's vocal-model workflow.

Verdict

ReSing is a strong fit for producers who want to transform vocals with detailed model controls and create voice or instrument models locally. Its main reason to choose it is that combination in a standalone or DAW workflow. The main reason to look elsewhere is the cost of expanding beyond the base generation allowance, especially if modeled voice work is not your primary need.
