Hi -
Ultra Rhythm Explorer seems to generate two extra lanes of MIDI that I did not input in my user Drum Set editor for Drumatic3. Notice in the image below the values B0 and A0 when using Drumatic3 [ http://e-phonic.com/plugins/drumatic3.php ]. All values in my user Drumatic3 drum set are set to "unknown" except for the 12 displayed in the attached image.
