  • Fixed – While holding down the sustain pedal, press and release some keys. If you now press and hold the same keys while releasing the sustain pedal, the notes get cut off. This bug makes piano-playing using the sustain pedal useless on the MS6.
  • Fixed – If you are in bank 1-7 and press some keys (preferably at least 6 different ones to make sure all voices are affected) below the lowest accepted key (C0), no sound will be heard. However, the envelopes for the allocated voices will be slowed down, which can be heard if you then play some keys within the accepted range.

  • Fully verified before shipping and professionally packaged in anti-static material.
