Sample Rounding Issue!!!!

If you create a clip on a track in "samples" mode that is 1/4 note long, it is unlikely to actually be exactly 1/4 note in ticks (because you're using a sample time base) - the "samples" time base though is very important to any of us working on non-tempo-grid based material (non-grid based music, time code based material, etc).

If you are in "ticks" mode, and your clips are created to be for example exactly 1/4 note then they will act correctly and you shouldn't have a problem. Pro Tools allows users the flexibility to have multiple timebases working in a single session and to move tracks freely between sample and tick timebase - I suspect that the people having problems with this have either created or edited clips on a track in "samples" mode and then changed it to "ticks" mode and expect everything to work just fine - it usually will not. I'd be very curious to see an example of sample rounding error on a tick based track with material that's been created or conformed to the tick grid - not saying it's not possible that there's a bug, but I'd want to see it.

Yes, definitively occurs on tracks in tick as well. However we are focused on midi clips, and these kind of data has nothing to do with tempo/SR calculation
