Please add a compatibility setting to (not) send initial CCs for the No SysEx/GM/GS/XG/GM2/NX reset options, and a new Reset Type called "System Reset" (sends FF).
Another compatibility setting to (not) reset manual mode overrides on song change (useful for some modules that don't support a specific controller or have an issue involving that controller).
And yet another compatibility setting to (not) send All Notes Off on pause (instead only use Note Off).
And please support those following SysEx to set the channel mode to drum for display (in addition to GS SysEx. Where nn is channel #):

There is an issue where the F1 key to set to the lowest octave for keyboard play conflicts with the Help hotkey.
