MeldaProduction MAutoPitch

MeldaProduction MAutoPitch is a free automatic tuning and pitch correction plugin for vocals and other monophonic instruments. It runs on macOS and Windows through VST, VST3, AU, and AAX interfaces for 64-bit systems, and its maker says it supports all major hosts on those platforms. Creative controls include formant shift and stereo expansion. Users can save settings in A-to-H slots and morph among the first four with an X-Y pad. MIDI controllers or a MIDI keyboard can adjust parameters in real time, with MIDI learn available. The plugin includes automatic gain compensation and a safety brickwall limiter that keeps output below 0 dB. Processing options include mono, stereo, mid-side, separate left/right or mid/side, surround up to 8 channels, and ambisonics up to 64 channels. MAutoPitch uses 64-bit audio processing and can handle any sampling rate. It is part of the free MFreeFXBundle, which contains 38 audio effects. Installation and activation go through MPluginManager. The maker says activation uses licence files without a dongle or internet access, and licences are tied to a person and usable on that user's computers.

MAutoPitch provides free pitch correction with additional formant, stereo, MIDI, and multichannel controls. Confirm that its host interfaces and the MPluginManager installation process suit your setup.

MAutoPitch suits musicians and audio producers seeking free pitch correction for vocals or other monophonic instruments. Its MIDI control and listed channel options may suit users who want to adjust parameters in real time or process multichannel audio.

MAutoPitch is a real-time pitch-correction plugin for vocals and other monophonic instruments. It best suits musicians working in macOS or Windows audio hosts who want tuning plus controls for shaping a sound. Its range is notable for a free effect, but it does not detect scale or key.

Overview

MAutoPitch combines automatic tuning with formant shift, stereo expansion, MIDI control and tools for comparing settings. That makes it useful when pitch correction is only part of the job: users can also adjust vocal character, control parameters live and move between variations. The compromise is that MAutoPitch works as a host plugin, so it is not a fit for someone seeking a standalone tuner or automatic key analysis.

Key features

• Real-time pitch correction: Designed for vocals and other monophonic instruments, it provides automatic tuning in the production session. There is no scale or key detection, so users who need the software to identify musical context should look elsewhere.
• Formant and stereo controls: Formant shift and stereo expansion extend the effect beyond basic tuning, giving producers options for changing vocal character and width.
• Setting comparison and morphing: Eight A-to-H setting slots keep alternatives ready to compare, while an X-Y pad can morph among the first four. This is useful for auditioning or blending settings without treating each variation as a separate setup.
• MIDI operation: MIDI controllers and keyboards can adjust parameters in real time, and MIDI learn maps controls.
• Channel and audio support: Processing covers mono, stereo, mid-side, separate left/right or mid/side, up to 8-channel surround and up to 64-channel ambisonics. The plugin uses 64-bit audio processing and supports any sampling rate, giving it scope beyond ordinary stereo sessions.
• Output and presets: Automatic gain compensation and a safety brickwall limiter keep output below 0 dB. Presets are stored in a system database and can be shared or downloaded through MeldaProduction servers.

Pricing

MAutoPitch is free: the free plan provides the effect, and it is also included in the MFreeFXBundle, which contains 38 audio effects. That makes it an easy choice for users who want pitch correction without a purchase.

The optional MFreeFXBundle upgrade costs $55, paid once and unlocks extended bundle features. It supports Windows and Mac, licenses all of the buyer’s computers and includes free-for-life updates. It is for users who want those broader bundle features; MAutoPitch itself is already free, so the upgrade is not required to use the effect.

Platforms

MAutoPitch supports 64-bit Windows and Mac through VST, VST3, AU and AAX interfaces, and MeldaProduction says it works with all major hosts on those platforms. Installation and activation run through MPluginManager, which installs Melda plugins and instruments, activates them and checks for updates. Activation uses licence files, requires neither a dongle nor internet access, and ties each licence to a person who can use it on that person’s computers.

Who it's for

MAutoPitch is a strong fit for vocal producers and musicians who need real-time correction in a desktop host, want formant or stereo shaping alongside tuning, or value MIDI control and broad channel support. It is less suitable for users who need scale or key detection, or who want a standalone app rather than a plugin. The required MPluginManager workflow is also worth considering before installing Melda software.

Pros and cons

• Pro: The core effect is free and also comes in a 38-effect bundle, so users can get started without paying.
• Pro: Formant shift, stereo expansion, MIDI learn, setting slots and morphing offer creative and performance controls beyond correction alone.
• Pro: Support for surround and ambisonics as well as standard channel formats serves sessions with more complex routing.
• Con: It does not detect scale or key, leaving users to supply that musical context themselves.
• Con: It requires a compatible host and installation through MPluginManager rather than functioning as a standalone app.

Verdict
