I have observed the following:

1. Random error where Audio drums are out of sync with the chosen style.

2. Random error with a low volume - high pitch background noise when choosing certain styles.

3. When using the CLASSIC B3 organ with the rotor effect the reverb of the voice is turned off when changing the rotor from from slow to fast.

4. Random flickering in the display when using the arranger conductor and changing right hand voices while playing.
