Thanks so much for the code. I got it to do exactly what I needed and this is going to help my workflow tremendously. We do a lot of keyboard midi recording and then do lots of splitting / punching in / editing and every damn time I would have to go back and add a pedal off because the previous notes would just keep sustaining.

Another side effect was tiny orphan notes where the split happened and I found the action to throw those "trailing" notes out. Here is what I got. Thanks so much !! Huge win for me. I hope it helps others and wish it was already built into Reaper as this seems a desirable midi behavior at least for me.

Would you be able to show me how to extend these two to work for multiple selected items (at same mouse/edit cursor position) on separate tracks possibly ? Basically for all midi items under the edit cursor.

This show splitting with no snap first and then with snap. Both cases show how the pedal off is now present.
