MIDI is just a set of instructions and requires either a hardware or software synth to make a sound. If you’ve had BIAB for at least four years, I hope you had something to play MIDI. Tell us what you selected in Options, Preferences, MIDI Driver, middle column (output). Also in that same window, is DXi checked?

There is a setting in BIAB that replaces MIDI Drums with RealDrums when it’s a better choice. I’ll try to find the setting so you can choose to use this feature or not.
