I recorded the track almost entirely from my keyboard. With minor edits in the piano roll. And you guessed it, the current notation is a total mess. It's absolutely useless as it is right now.
It can probably be improved greatly with the right settings, and some additional editing in the PRV. Here are the main things you will need to do to get the piece to display well as notation:
- Record the piece to a click or align SONAR's timeline to it after the fact using Set Measure/Beat At Now (nothing will work as expected if the MIDI isn't closely aligned to the timeline with the correct meter(s) set).
- Manually split left- and right-hand parts of the original track to two new tracks, and designate those two tracks the bass and treble clefs of a grand staff in the Layout section of the Staff View.
- Quantize note start times of these two 'notation' tracks to 100% at the appropriate resolution.
- Set the Display Resolution appropriately, and enable Fill Durations and Trim Durations.
- In areas that still don't display as expected, you will probably need to to do some manual trimming/filling of durations in the PRV to get the desired result.
Depending on the style of the composition, there may still be things that SONAR can't get right, but if it's a 'simple piece' as you described, you should be able to get a serviceable result.
