MeldaProduction MAutoPitch vs Softube Vocal Tuner

MeldaProduction MAutoPitch is a free automatic tuning and pitch-correction plugin for vocals and other monophonic instruments. It provides formant shifting and stereo expansion, and offers eight A-to-H setting slots; an X-Y pad can morph among the first four. MIDI controllers and keyboards can adjust parameters in real time, with MIDI learn. Automatic gain compensation and a safety brickwall limiter keep output below 0 dB. The plugin supports mono, stereo, mid-side, separate left/right or mid/side, up to 8-channel surround, and up to 64-channel ambisonics. It processes audio at 64-bit and the maker says it handles any sampling rate. MAutoPitch runs on 64-bit Windows and Mac through VST, VST3, AU, and AAX interfaces, with support for all major hosts on those systems. It is included in the free MFreeFXBundle of 38 audio effects. Installation uses MPluginManager. The maker says licence-file activation needs neither a dongle nor internet access.

Softube Vocal Tuner is a real-time vocal pitch-correction plug-in for macOS and Windows. It runs inside a DAW host that supports AU, VST, VST3 and/or AAX plug-ins. Classic correction targets a traditional sound, while Modern correction is designed to preserve vocal formants. Subtle/Hard changes correction speed, and Natural/Robotic changes correction on note transitions. Pitch and formant shifting can work independently or together. Octave-up and octave-down layers have separate gain controls, and Tone Enhance adds processing. Low Latency mode is intended for tracking and live performance, with reported latency under 1 millisecond. Metering and visualizations show the input signal and processing effect. The plug-in supports MIDI pitch control and a 12-semitone pitch-shift range, but has no scale or key detection. It costs 199.00 EUR once, includes a 20-day trial and three activations, and requires Softube and iLok accounts plus internet access.
