Ok I think I got another one, a bit more serious.  When using the special paste.  I wanted to copy my volume enveloppe only. It still scrambles the notes unless you are pasting it against a single note that is formated exactly like the one you copied.  In other words if I paste it on a single note, of the same length as the original one, with the release at the same spot, it works fine. But if the release is not at the same spot, it deletes the release. If you paste it on something that has more note than the original copied material it removes the extra notes. I have experimented with some variants and my feeling is that it will keep a note or a release only if there was one at the same spot on the original material. Again, that is with the special paste and only volume enveloppe selected.  

For the alt + mouse wheel -  Firstly it does it only with left alt.  Right alt does not do it.  And I noticed that I do not actually need to do them at the same time. If I press Left-Alt once, it locks the mouse wheel and  wheel click.  Edit ( it seems to be left-alt release that causes the issue. If I press and hold alt the mouse wheel keeps working until I release it ) 

Ok next one. If you try to copy or cut a pattern selection with no pattern in it. ( Don't ask why I even tried that ) 

It results in a nasty pop-up.

Another minor thing I forgot to mention. The special paste window text is cropped. It seems to be a system scaling issue. My system scaling is at 150%. If I change the settings in Famistudio it does not fix it. However setting my whole system to 100% fixes it.

Indeed I had missed the message as it was posted in between older messages.  I think it does that when you post something from an instance of the webpage that was not refreshed with the lastest posts. 

I used ScreenToGif and made a Demo. As you can see, with the first paste it keeps the notes as they are formated the same regarding relative start time. But the second Note release is lost as it was not at the exact same place as in the original material. With the second paste, the notes are lost, except the first ( edit : and third ) one. 

This should come handy! Will it be possible to tweak the magnet to match to half notes, third, quarter etc ? I suppose that might be a challenge considering the 60hz frame system has a high granularity.   How do you compute a half note when when someone sets their note to have an odd number of frames ?
I very much like 12 frames per notes so far. Works with half, quarters and triplets. 

Thank you for the continued development, I am really becoming addicted to famistudio. I have a new song coming nicely but I am now at the stage of tweaking the parts I don't like and this takes forever. 

 A few ideas 

1. Gray out the options when dividing the note in even parts is not possible.  
2.  Allow using it and round up or down but it always notches on the first frame of a note.
3. Magnet setting uses frames instead of note divisions.  Right click magnet opens a box where you just type or click up or down the number of frames you want between each notches. It always notches on the first frame of a pattern then  follows along the grid you asked for.  ( The more I think about it, the more I think this is the best option )

That looks perfectly good to me ! Does this also work with Famitracker mode ?  

Right Clicking an enveloppe space where there is no pattern = pop up error

This is gonna be great! Likely my most wanted thing from the wishlist.  Will it also work with groups of patterns ? That is something I had not talked about in my original wishlist.  Just the other day I wanted to copy a bloc of 3x4 patterns as new patterns at the other end of the song. The contemplation of having to do it manually one pattern at a time in the piano roll was depressing ( I still did it ). 

Yeah the thread is a mess and has basically become general chat.  The forum will eventually need sections but I suppose right now there are not enough users to bother.
