Audio Scale - Midi Controller

Hi Team.

I have been looking at the Midi controller interface data, and how it equates to the data within the UI within Wirecast.

When moving a fader for audio volume levels, a midi value of 111 equates to a volume level of 99%, and a midi value of 112 is 101%. What is missing here is the elusive 100%. It is impossible to set the volume using the faders to 100%.

Yes, I am being pedantic - but it would be great if the scale that maps the midi values to volume levels could be adjusted so that it is possible using a midi controller to set the volume to 100%.

  • That's an interesting idea. I'm sure you've put that in as a feature request.

  • I did some research to find the root cause: Below is a table of midi value to volume level mapping. The left column is the input value from a midi controller, and the right column is the volume level in Wirecast. There is a duplicate mapping to volume level 98 from two midi values. This is a bug/error that was not intended.

    This can be fixed by updating two values in the table. The corrected values are below.

    This is in the community tracker with an associated bug ticket. The good news, is that this is 100% reproducible - and even better - fixable with a tweak to the tables as shown below.

  • In my opinion, it's easier to think in the lines of "I'll play all those keys raised by x steps" or "I'll make chords on all those keys except those out of scale", than to learn a lot of positions. For example, once you know the F Major scale features a Bb instead of B, then it's easy to make the right chords to fit the scale.
