Hi bharris
Yes that is correct - once you have found the channel the melody is on in JABB with your alto sax - save the configuration and then every time you open JABB you can load that saved confiuration
One caution - it is a long time since I used it so I might have things around the wrong way but I do remember that it did not work channel by channel
Also check that the volume for the melody channel in JABB is not muted or tuned to zero
There is not a bug but the way both programs work and once you have it then it is easy
