Midi editing - wrong notes are playing?

I know this problem has something to do with Reaper's refusal to erase notes when you punch-in. It's such a different system fromProtools, I just can't get a handle on it, and now I'm really stuck: I've seen before that if I punch-in on a track (hard to do with no pre-roll!) that the old notes, past my punch-point, don't go away. They are hidden from view, and maybe not active, but still there. OK, a silly thing, but I figured out how to deal with that. Sometime later, I learned about glueing audio track pieces together. I was REALLY tired of having to constantly open separate midi "boxes" when editing my midi notes, so I thought I'd try the "glue" command on a midi track. Well, it sure looked like it worked. All the vertical separation-lines went away, and I had what APPEARED to be one continuous midi track, with only my "good" notes left. Now I am trying to edit that midi track, and it's totally FUBAR. I open it up to edit, and sometimes the edit works. Other times, the edit does nothin, and apparently some hidden midi notes are actually playing, not the ones I'm looking at. I think maybe the punched-over notes got combined into the new track, instead of the "good" notes, when I glued it all together. Yes? Ughh. So, now what can I do?

No one has an answer? Can I somehow undo the glueing, and remove the bad notes?

Jeez ..... Tumbleweeds are blowing through my thread.

I'm not sure exactly what your issue is and I'm certainly not the most knowledgeable person around with takes, but I'll see if I can help. First, do you have "show all takes in lanes" enabled? Select this from the options menu or simply press "Ctrl + L." When you have multiple takes on a track, you have the option of seeing them all or only seeing the active take. If you have room on your screen, you might as well see them all. Make sure to enlarge your track by clicking on its bottom edge in the inspector and pulling down. Now, when you glue those pieces together, it should only be gluing the active takes. But, you can try deleting the bad take by selecting the section of the track with multiple takes, then right-clicking and choose "crop to active take" (assuming the take you have active is the good one). Remember to ctrl + z to undo. I have a question for you though: you mentioned notes still being there even after your "punch point." You mean your punch-in point, right? Obviously you want to keep notes after the punch-out point. Resizing the track size and pressing "Ctrl + L" should show all the takes. But, you can also have a pre-roll (that's what the joy of punch-in recording is). So, let's just make sure we're on the same page with how we're doing our punch-in recording: 1. Record a track normally. Sadly, one part of the track needs to be re-done. 2. Go to options. Select "Record mode: time selection auto punch." 3. Time-select (go up to timeline and drag) the areas you want to re-record. 4. Now click where you want the song to start playing from to give you context. 5. Press "Ctrl + R" to record. Note: even though you pressed record, only the time selected area will actually record. So, the song will play from where you clicked and only become record-active when you hit that time selection. This should gives ample context for the punch-in section. Let me know if any of that helped. Sorry if I dumbed down anything too much.

Well, This doesn't explain what happened, how I can be hearing different notes than what I'm seeing on the screen. However, your explanation of the pre-roll work-around is very helpful, thanks. -But good Lord, is that a cumbersome way to work. Why on Earth doesn't Reaper have a pre-roll function? Is Justin just purposely torturing us? I'm guessing it has something to do with reaper's lack of a true "input" mode. (which is another mystery for the ages) Still, much obliged! ---------- Back to my original problem: Can anyone explain what actually happened here?

Maybe I am misunderstanding the problem, but this looks Ok to me: Big pic: - track 3 is my first recording, - I set my Recording Mode to "Time selection auto-punch" and put the play cursor at 2.1.00 so I could hear the first recording, - I then clicked Record and punch in a second take, - track 4 is the same MIDI recording with 1 bar over-punched, After this second take I expanded the results, - tracks 5 and 6 show the first recording now as three MIDI Clips, - actually the contents of each of these three clips is the complete first recording, the differences are the "Start in Source" and "Length" values; may that should be changed, to contain only the notes on display - track 7 in my punched-in clip, I have expanded its edges to show that it starts where recording started and ends where recording ends - track 8 is the result of glueing together the 3 clips on track 4 - with the second take selected; I get 2 bars of the first recording, the 1 bar punched-in recording followed by the final part of the first recording. Isn't that what you're looking to do? If not, then please post an example project here with similar screenshots so we can understand the problem. HTH
