Welcome to the forum.

You probably know this, but in the MIDI world, instruments are called Patches. The column on the right for Patch Change is where you make the changes.

However - if you would, please tell us what version of BIAB you have, and what build. Go to Help menu, About and you'll see that info. There have been some recent patches that might affect this.

What do you use for your MIDI sound? A hardware MIDI synth like Roland or Ketron? Or a software instrument? You could tell us what you have in Options Preferences MIDI Driver, the middle column. You would adjust the entry in Patch Changes for whatever the name of your Melody instrument is, six positions from the top, or three from the bottom.

And, is VST/DXi checked?
