Dear William

On my previous post, you will find a link to this video:

I also put the time marks were you will find all the information. You are looking for step 9 of the FCB1010 setup:

• Now you can enter the note number that you setup on the Tyros. It will display a table with the equivalences of the note numbers and the musical notes on minute: 7:05

So, in the time mark 7:05, you will see that the person of the video put a table, see:

He says this:

C#-1 = 13
D-1 = 14
Eb-1 = 15
E-1 = 16
...
F#1 = 42

Best regards
Josef
