When dragging the instrument from melodic bank xx.00 to the instrument editor, it assigns the right MIDI program and bank, but setting the plugin to MIDI out and the engine to Microsoft GS Wavetable Synth results in only GM instruments of the same program number being played. Has this already been reported before? I don't know about the severity or priority, as it simply only makes it harder to use it as a MIDI composer with a better interface and the user wants to go beyond GM instruments.
