It's also a real pain if you want to look at, and edit, MIDI note numbers for Drum tracks, brought in as a MIDI file, from another source.
In Cakewalk Sonar, it was always pretty easy to split a track to separate tracks by note number, then transpose, for example the kick drum from note #35 to #36. The other option in Sonar was to apply filtering to what you're selecting within one or more midi tracks, such as controllers or note numbers or ranges of notes, then you could perform edits on the selected data such as transpose, adjust velocity, cut, delete, copy, etc...
I really, really miss the MIDI Event List in Sonar. I have to keep it around for this reason, so I have to do a lot of import/export, and still work on my MIDI tracks in Sonar. Then, I bring the 'finished' MIDI into S1 and do audio. If I run into an issue with a MIDI track, that isn't convenient to deal with in S1, I have export everything from S1, and start over from Sonar. A MAJOR BUMMER.
