The built-in mic and speaker make it easy to record and play back your practice sessions

Since a mic and speaker are built-in to the TMR-50, you can start recording when the moment is right.

Of course there is also an Input jack and a Phones jack, so you can record via a contact mic or play back the audio through earphones.

There's also a convenient Loop Play function that repeatedly plays the specified region of the recorded data, allowing you to practice along with a specific phrase.

In addition, the tuner, metronome, and recorder can be used simultaneously for even more effective training.

The TMR-50 can help you check your playing in a variety of ways that will help you advance as a musician; you can record with a metronome pre-count, record a "tempo sync track"

* that lets you check whether you were in time with the tempo during playback, or you can activate the tuner during playback to check your pitch.

*During recording, you'll be able to monitor the metronome sound in real time through the Phones jack.

USB Connectivity

If the TMR-50's recording memory fills up and you want to save data, you can copy it to your computer via the USB connection.

The data is saved in WAV format, so you'll be free to listen to your practice sessions on your computer whenever you want.

Standard WAV format files can also be copied from your computer to the TMR-50 and they can be listened to through the built-in speaker or headphones*; for example, you may find it convenient to store the original recording of the song that you want to practice.

*If the WAV file is stereo, you can enjoy stereo playback via the Phones jack.

The Sound Back Function

You develop the ability to hear and produce the correct pitch.

That's why the TM-50 provides the proprietary Sound Back function* that until now has been featured only on Korg's high-end tuners.

Detecting the pitch of your audio input, this function sounds the nearest reference tone from the speaker while the meter shows the pitch difference between your input and the reference tone.

Since the pitch is indicated in both visual and audible form, this not only allows you to tune more accurately, but is also an ideal method for training your sense of pitch.

Developing your ear in this way is an indispensible way to practice, especially for the beginner.

*This function is available for input via the Input jack or when using headphones.

*When using the recorder and tuner functions simultaneously, the tuner section will be usable only in Meter mode; the Sound Back function will not be available.

Marks Indicate Pure Major/Minor Third Intervals

When performing in a brass band or orchestra, incorrect pitch is particularly noticeable for harmonic intervals of a third, yet by slightly skewing the pitch of a major or minor third interval from the equal-tempered pitch, you can obtain a more pure-sounding harmony that satisfies the ear.

The meter scale of the TMR-50 provides marks that indicate pure major and minor thirds relative to a given pitch; simply by tuning.

When the needle aligns with the appropriate mark*, you'll be able to produce beautiful harmony when playing in an ensemble.

This is extremely convenient not only for wind instruments, but also for vocal or a cappella practice.

*When tuning to a pure major or minor third, the note that should be adjusted will depend on the music you're playing.

Easy Tempo Settings

When setting the tempo, you can choose either "pendulum steps" where the tempo will increment or decrement in the same numerical steps as on a mechanical metronome, or "full steps" which allows you to specify any tempo between 30 and 252 in one-step increments.

In addition, you can also use the tap tempo input to specify the desired tempo simply by pressing a switch in time with the beat.

Memory Backup and Auto Power-Off

Even when you turn off the power, the TM-50 will remember the tempo, beat, rhythm, calibration, and reference tone settings that you've specified (these settings will be initialized when you replace the battery).

The Auto Power-Off feature will automatically turn off the power if twenty minutes have elapsed without any sound being input to the tuner while the metronome is not running.
