M Tuner
Mtuner
Free Polyphonic Instrument Tuner Plugin
MTuner is a powerful, precision-focused tuner plugin designed for guitars, basses and a wide range of instruments. Built around MeldaProduction’s high-resolution analysis engine, it combines a classic monophonic tuner with a fast, accurate polyphonic mode that dramatically speeds up restringing and setup sessions.
Whether you’re tracking DI guitars, reamping bass, or working in post-production, MTuner delivers reliable pitch detection with the kind of technical depth usually reserved for paid tools.
System Requirements:
- 64 bit
- VST / AU
- Windows
- macOs
Monophonic & Polyphonic Tuning in One
MTuner features a traditional single-note tuner alongside a high-resolution polyphonic tuner that can detect and analyse multiple strings simultaneously. Instead of muting strings one by one, you can strum and see everything at once, ideal for quick session prep or live environments.
Under the hood, the tuner includes adjustable stabilisation, frequency range limits and selectable pitch detection modes, allowing you to optimise performance for different instruments and pickup types.
Advanced Analysis & MIDI Output
Beyond tuning, MTuner includes an integrated audio-to-MIDI converter with threshold control, velocity scaling and optional pitch-bend output. This opens up creative routing possibilities inside your DAW, from triggering instruments to generating MIDI from live audio.
It also supports extensive channel modes including Mid/Side, surround (up to 8 channels) and even ambisonics processing up to 64 channels, making it suitable for immersive and post-production workflows.
