Default MIDI item misplaced loop notch

Hi all,

First time i run into this but very timeconsuming and annoying:
I recorded V-Drums in reaper and midi is played through NI Studio Drummer. Nice.

But when I split this midi track (through regions or directly) somehow some bars before the split the track gets the symbol as if it were a loop; and, although the midi notes are visible, it is silenced until the part after the split. What happens? Am i misunderstanding parts of MIDI?

Thanks for your help, this is a real blocker!

I'm not sure that I have understood properly, but ...

Splitting a MIDI clip only sets that start and end positions within the clip. No notes are deleted. After the splits you might try Glueing each clip separately.

If that does not help, perhaps you could compress two ataes states of a simple problem project file (no audio samples needed) into a ZIP file and post it here as an attachment so that we can have a look at it and see what's (not) happening? The two states are before you have split the MIDI track and afterwards, indicating what has gone wrong with a few screenshots.

Thanks for your help Darkstar.
What do you mean with ataes?

I’ll post extra info tomorrow; screenshots and / or
Project file.

Thanks again!

Oops. I meant 'states' - I've fixed the typo.

Default uploaded RPP

So I added a MIDI file with Kontakt Studio Drummer as a plugin on the MIDI track.

I must say it was hard for me to generate the erroneous behavior, weird since it happened all the time yesterday.
Anyway, you can see any time you're splitting the track the weird 'loop-like' appear (see attached image).

Exactly at the start of the region (11 A - solo 2) the few MIDI notes there do exist but are not sounding at my laptop. I think this might be representing the behavior I dont understand in general.

Thanks for your help!

OK, I can see the glitch - it looks like a graphics glitch to me. If I drag the end of each clip (or Glue each clip separately) then it goes away.

So it looks like a buglet to me. It's got something to do with the time signature / tempo changes - if I remove some of them the glitch disappears too.

Also, I see that the name for some of the clips is not displayed either. That's another bug.

Ok... So is something I did wrong / misunderstood or is it a reaper bug?

English not being my native language, I don't really get what to do to workaround it.
I use a lot of different time signatures... Hope thats not causing issues,

Thanks a lot!

They both look like bugs to me.

The simplest workaround is to select the problem clip, rgiht'click and select "Item operation" then "Glue items".

Mods: please move to Bugs sub-forum

trifonius:
Since these problems appear to be bugs, so would it be OK if I move this thread to the Bug Reports subforum?

The misplaced loop notches is a display bug that I often run into in my own projects, and I also think it is somehow caused by timesig / tempo changes.

Even stranger to me is the fact the the notes at the start of the Region "1 A - solo 2" do not play -- but only if the play cursor is placed at exactly the grid position 33.5. If the cursor is slightly before or slightly after the grid, the notes do play.

Hi,

Yes Please you can move it to the bugs forum.
I am not an experienced forum user;
How is followup handled from there?

Thanks guys!

Done. (I also took the liberty of changing the thread title.)

Sadly, you just wait... and hope... The backlog of MIDI bugs is very long and MIDI has received painfully little attention in recent versions.

One year later, I took a look at this problem again, and realized what the problem was:
* There was a teeny tiny, empty MIDI item, less than one tick in length and practically invisible, overlaid over the long MIDI item at the start of the region.
* The project's item mix behavior was set to "Enclosed items replace the enclosing item".

The tiny MIDI item therefore blocked the note-on events from playing, if playback started precisely at the start of the region.

If playback started a little later, beyond the tiny MIDI item but before the note ends, REAPER would chase the note-ons and play them.

(I therefore removed the second part of the thread title, "2) Note does not play when playback starts at grid".)
