Dear George ,
Thank you for enlightening on the technical datails of this fine keyboard. It seems that you are going to 1000s of 625.
However, there is still one thing that is unclear to me (maybe due to my limited knowledge of technical English).

What does "5 types of Master EQ" mean?

Is this a 5-band equiliser or just 5 eq. presets?

Regards,
George V
