I'd like to translate some parametric EQ settings from other devices to the H9 and vice versa.  On the H9 'Width' is implemented as a number from 1-10, where 1 is narrowest and 10 is widest bandwidth but on other devices it's given as 'Q' with the bandwith inversely proportional to the Q value, (eg 10 being the narrowest and 0.1 the widest).

What units are the H9 Width given in and how can I accurately translate between it and Q?

 

The Width units are just arbitrary 1-10 meant for tuning by ear.  However, I did some digging and found what the exact Q values are under the hood.  They are represented in these 10 values (corresponding to Width 1-10): 

10 8 5 3 1 0.9 0.8 0.7 0.6 0.5

For Width values in between integer values, the Q values you see above are simply linearly interpolated b/t their corresponding values.
