Hi,

 

I control my H9 from a Boss ES-5. I also need to be able to change the output level of a preset via the cc.

I use cc#33. It seems to work.

 

But when I import the preset from the H9 to the iPad. The output level is always at 0.

Is it a bug in the application?

 

I also notice that the output level range is from -30db to +20db.

The cc range values is from 0 to 127.

Do I really need to do some arithmetic to calcule the values?

Example

The cc value for +3 db = (3 + 30) * (128 / 51) = 82.82 = 83

The cc value for +4 db = (4 + 30) * (128 / 51) = 85.33 = 85

The cc value for +5 db = (5 + 30) * (128 / 51) = 87.84 = 88
