I've recorded several MIDI files with my Kawai CP150 digital piano, and I've noticed that when I import them into Sonar, their resolution is 96 ticks. I want to be able to convert them to 960 ticks, but when I switch that on in the Clock tab of the Project Options dialog box, nothing changes when I play it back. Also, how would I convert a MIDI file from 4/4 time to 12/8 time, while keeping the eighth-note triplet rhythm?

Have you tried to import these MIDI files to another software (Sibelius, Finale) or another DAW?

When I import it into Sibelius, it will let me change the tick resolution and time signature, as well as double or halve notes to my liking. However, in the original MIDI, when importing into Sibelius, some long notes appear as one or more short notes tied together. That's rather strange, because the notes appear in Sonar the way I want them to. The way I know what notes are what in Sibelius is with Sibelius Access, a set of accessibility scripts that works in conjunction with Sibelius 5 and JAWS. The way I know what notes are what in Sonar is with the Event List and Caketalking, a set of accessibility scripts that works in conjunction with Sonar and JAWS.

What are you expecting to change on playback? Midi ticks are just higher resolution Pulse Per Quarter note. ( upon capture ) Nothing will change at playback from the original resolution it was recorded in. Maybe if you compared available time edits with in the event list you would see a higher resolution available for the 960 converted file.  New tracks should be higher resolution when played real time, IE ( no quantizing )

When you change the resolution of your MIDI file from 96 to 960 ticks per quarter note, you're only changing the internal structure so that events can now be moved forward and backward with finer precision.  The events already present will not change temporal positions.  The MIDI file will sound the same whether the resolution is 96 or 960 ticks per quarter note.

As regards the time signature from 4/4 to 12/8, while keeping the eighth-note triplet rhythm....  I'll leave that up to some one else to answer....

A 96PPQ track in a  960PPQ project will just look like all the start times and durations have been quantized to 10 ticks. As others have pointed out, you won't recover any timing precision. Recording at 96PPQ in the Kawai already threw away that information. FWIW, unlike your Kawai, SONAR/CbB always runs at 960PPQ internally. Even if you set it to something lower, it will record and play back with 960PPQ resolution and just display the rounded/quantized times.
 
Likewise, changing the time signature won't change the playback timing of the MIDI. The M:B:T times of event will just change to fit the meter while their absolute timing is preserved. So, for example, an 8th triplet at 2:01:640 in 4/4 will display as 1:10:160 in 12/8. Either way, at 120BPM (a 'beat' is always a quarter in SONAR, regardless of time signature), that note will start at 2.333 seconds.
