Independent shopping perspective
The Korena take
KORG’s white TM-70T puts chromatic tuning and metronome work in one compact unit for wind and string players. It reads pitches from C1 to C8 with better than ±1 cent accuracy, while Meter, Sound Out, and Sound Back modes cover different tuning approaches. The metronome runs from 30 to 252 BPM, with tap tempo and several beat patterns for structured practice. F, Bb, and Eb transpose settings make it useful when working with transposing parts.
Strong match
Who this is for
- Wind or string practice that needs a tuner and metronome in one compact device.
- Working through transposing parts in F, Bb, or Eb during focused practice.
- Quiet practice with headphones connected to the 3.5 mm stereo mini jack.
