FL 10 arguably has one of the best piano roll editors, imo. If you reduce midi editng down to only that, it's hard to beat on a practical level. Of course, like most things midi editing isn't a one dimensional thing. But for sure, the piano roll editor in FL Studio is pretty well done.

It's midi is pretty well designed overall though... even if not all that conventional in the sense of a Cubase and similar.

Anyway, I often refer to Cubase because it's midi editing is kind of multi-dimensional. Ranges, notes, whatever, can all be attacked directy from multple angles or methods. For depth of editing it's probably the standard. Of course, not everyone needs that.

But it has... what... 5-6 different midi editors? Let's count them...

1. Key Editor + in place.
2. List editor which also has a graphic key editor component.
3. Drum Editor.
4. Score editor.
5. Logical Editor.
6. Input transformer, which is 4 real time midi logical editors, per track.

As relates to running an edit action for midi data, there's very little (if anything practical) that it can't do with midi data.
