VOLUME CONTROL BY RANK MESSAGES

 

 

It is possible to exercise Volume Control of entire ranks by means of the disposition Rank messages (Data 2 - last number

i.e. set "n"). The default for "n" is 100, with a maximum of 127. In some of the tests on which this article is based I included sounds that had already been attenuated by 10 dB using the soundfont Attenuation Setting, and found that these tracked well with the sounds with no such attenuation. Here are the results:

These levels were measured by making audio recordings using Cantabile and opening these files in Audacity, and then using the Analyser.
