Ever since the advent of Sonar X1 manual entry of MIDI data has become very cumbersome, so much so that I use Sonar 8.5 to type in MIDI data.  Sonar X1, X2 and X3 does a lot of things better than ever before but it has missed the mark on MIDI data entry.  You guys really need to work on that!  Until then I'll continue to use Sonar 8.5 for entering my MIDI data, of which I do a lot.

That change is what drove me away from Sonar and on to FL-Studio, which isn't as good overall, but has fantastic manual MIDI entry capabilities.
