    Why are the pitches or intervals wrong on my Yamaha Synthesizer S90 ES?
    • J
      Jacob ScottSep 2, 2025
      Incorrect pitches or intervals on your Yamaha Synthesizer S90 ES can stem from several settings. Check if the Master Tune parameter is set at a value other than “0”. Also, verify if the Note Shift parameter is set at a value other than “0”. When the voice produces a wrong pitch, make sure the appropriate tuning system is selected from the Micro Tuning parameter and that the LFO Pitch Modulation Depth isn't set too high. If the Performance/Multi produces a wrong pitch, check that the Note Shift or Detune parameter of each Part is set to “0”.
