Good tuner. The main and monophonic tuner is pretty well. It offers a stabilization feature of up to 1000 ms, which determines how long a detected note last on the display. For those who can't read in the speed of light, a great feature.

The polytuner feature unfortunately not serves its purpose. The actual notes do not get recognized, like it is the case at the main (monophonic) tuner. Rather it displays a fixed visualization of the determined notes and an amount of how much (I guess in cents) you are away from the correct tuning. No numbers, nothing. Just a few peaks going up and down.

Also the peaks last too short to really get an impression of the actual tuning of the string (it misses the stabilization feature of the main tuner).

That does not work out well.

But a cool thing about MTuner is that you can feed the detected note (as well as the pitchband data, if "Emit Pitchbend" is marked) as MIDI data into any synthesizer or sampler with a little routing.

That can lead to good results when you want to space up a little too monophonic content.

This tuner, like rest of software from Melda is not really free. Its adware. It annoys you with red banner asking for 30 USD. Also screen UI resizing and antialiasing is disabled.

Tuner can do basic mono and poly tuning. Authors are quite optimistic about poly tuning - they have in configuration space for 8 note polyphony. In reality poly tuner has problems even with 2 bass sounds.

Basic tuner has high accuracy mode but because it displays just 1 decimal digit in Hz, I can't cross check it with other free tuner GTune and my KORG tuner. You can configure stabilisation time - 100ms by default.

Included is also volume meter. It takes too much space on the screen and its not clear what kind of measurement is used - so pretty much useless, we have good meters in DAW already.

UI is not nice at all, it is using Accordion for configuration. Why not tabs? It takes so much screen space just for tuner.

Newbie question - I downloaded the Windows plugin but cannot activate MTuner. I'm using Reason 12 and Ableton Live Lite 11 and can get the VST to show but dragging the License/ copying the text to clipboard gives an error (unsupported) and browser does not show the license. Am I using the right license file? mlicencemanager DAT file.

Thanks in advance.
