QSI decoders had indices. Like a library, you had to acquire a 'row', and then get the book once you had the row. To change Master Volume, for example, you had to first set CV49 to a number clearly spelled out in the manual, and then go to another CV and set the volume for that particular sound, say whistle or bell. Yeah, it was a bit cumbersome, but it worked reliably and did what you hoped it would do.
