GLUE ITEMS - LATENCY-Problem within 1 bar

rin99er · 11-29-2018, 11:07 AM

Hi guys,

today i was drum editing and then wanted to support my kick with a sample.
my kick-track is spliced into different items so i wanted to glue them to one befor going on.

AND NOW THE WEIRD THING: WHEN I GLUE THEM TOGETHER, I HAVE A DELAY WITHIN 1 BAR

for example: the kick hits 4 on the floor, then the 1st hit is exactly where it should be, the 2nd one is delayed 2ms, the 3rd one is delayed 4ms an the fourth 6ms. then the next one (the 1st of the following bar) is exactly where it should be again, the 2nd is delayed 2ms again and so on...

i also have this problem when i render the track, or route it to another track and record the output.

i think i found out that this problem only happens when i have stretch-markers in that item... i don't know if this makes any sense...

i really have no idea what this is, thats the first time i recognised it.

please help me, i'm in ahurry with this album and i can't get the job done with problems like this

thanks to all of you
all the best

Sounds like a problem with Project settings and item settings i think, beats,position,length, rate v Time

rin99er · 11-30-2018, 03:28 AM

Thanks for your response.

I’ll check that later in the studio... dou you think that the default settings have been changed? What are the defaults?

Best

rin99er · 11-30-2018, 07:21 AM

Nope, i checked everything in project settings, item settings etc... nothing helped

Anyone else? Any ideas?

Geoff-h3o · 12-01-2018, 08:51 AM

You can set the default base as either time or beats according to what you want/need. Also R-click on any media item to look at it's properties. Stuff behaves differently according to what's been chosen.
There's lots of info in the manual and youtube.
I would think, if only one track is affected that you should try gluing it
with different item settings. If this doesn't work post your present settings
here; it might help someone spot the problem.

rin99er · 12-03-2018, 09:15 AM

ok... so i checked my prject settings, here they are:

i also tried every combination between TIME / BEATS (position, öength rate) / BEATS (position only) and TIME / BEATS...

in the item properties the same, tried everything but nothing worked.

i have screenshots in my dropbox https://www.dropbox.com/sh/k262m6rvr...IhY10LLLa?dl=0 - sorry, i didn't know how i could get them pictures small enough to upload them directliy here

A short update:

The flrst time i recognised this problem was after installing a demo of „slate trigger 2“... now i uninstalled, even reseted my system (windows 7) to a date 2 weeks ago (before this problem happened), but nothing changed.
I even reinstalled reaper, to my harddrive as well as on an usb-stick, portable install, but the bug is still here.

I‘m really starting to get desperate and depressed, i‘m stuck in this situation and can‘t finish the album... i am not able to work in any way

Does anyone have an idea, can chime in and help me? PLEASE!!!!

Geoff-h3o · 12-05-2018, 03:31 PM

Hi
I think you need to change the ITEM properties to beats/position legth rate, ie, to the same as the project settings. That, at any rate is where I've sometimes run into problems. It doesn't really make sense to me why this should affect rendering and I wish some one more knowledgeable than I would chime in. However changing item properties as above is certainly worth a try. Hope it works for you.

poetnprophet · 12-05-2018, 04:00 PM

I see in your project settings that time base is set to BEATS.

In item settings time base is set to TIME.

You need both to be TIME.

rin99er · 12-06-2018, 10:55 AM

hi guys,

thanks for your answers... they sound really good and make sense, i tried them, but it didn't help.

i made a screen-video to make sure i didn't miss anything

am i doing something wrong?

all the best

Geoff-h3o · 12-06-2018, 12:11 PM

Rather than glue the item could you sidestep the issue and render it to a new track?

rin99er · 12-06-2018, 02:11 PM

I tried, but that doesnt work...

I also tried render fx to the track, route it to another track and record, even use outboard ad record it back, the problem is always the same

Geoff-h3o · 12-07-2018, 02:40 AM

Does this track play back ok prior to rendering?
If so can you capture it by recording your soundcard's output (Audacity has this option; don't know offhand whether Reaper does)I guess when you say outboard you've done the equivalent but if it sounds ok when you play it back then surely capture by something else should be ok?

poetnprophet · 12-07-2018, 10:52 AM

I don't know much about Snap Offsets, but could that be the issue? It seems like it's a uniform shift when you render so that's what makes me think of the snap offsets.

rin99er · 12-09-2018, 12:26 AM

hi guys,

i'll check your suggestions later in the studio...

a short update:
i downloaded and installed reaper at home on the office-laptop. then i imported a soundfile, set 3 stretch-markers and stretched the audioclip, duplicated the track and glued the copy. the problem is there.
so this means its a reaper-"bug" by the default. -> if you guys never changed something in your defaults, you have to have the same problem.

can you try it for yourself?
i made a short clip of how i do it, please repeat my steps and look if you have the same problem. if not, can you export your reaper-settings and send them to me?

here's the video

thanks for everything

Robert Johnson III · 12-09-2018, 01:26 AM

Confirmed... This should be fixed ASAP!

MikComposer · 12-09-2018, 01:31 AM

I've been experiencing this issue since r4, where glued midi items wouldn't sound exactly the same as they were before gluing. Sometimes upon investigations I could see at high zoom levels notes being misaligned.

rin99er · 12-09-2018, 01:44 AM

@mikcomposer
Were thie midi-items time-stretched?
With audioitems the issue is just with time-stretched items

@robertjohnson
I absolutely agree. It‘s not just the glueing, its also when i render or re-record this track.
This means that all is good as long as i stay in reaper, but when i want to listen to my track in the car, i render the song and the weird thing is rendered in! Thats an absolutely no-go

Goldreap · 12-09-2018, 05:56 AM

Confirmed here.

rin99er · 12-10-2018, 06:54 AM

Hi guys,

Today i wrote Kenny Gioia and the official Reaper-support, i hope they can help us and solve the problem.

Just a short update
All the best
Rene

rin99er · 12-16-2018, 06:53 AM

Hi guys,

still heren't something from Kenny or the Support.

I made two update videos because i found a setting where it works a little bit like it should. It's no solutions, but i want to let you know about it.

As i mentioned before, THIS IS A REAPER-BUG BY DEFAULT - You all have to have this problem. If you don't, you changed your settings in a way it should be, so please export your reaper-configurations and let us all download it, because thats an absolute no-go for a daw, though i love Reaper.

Great sundy everyone
René

Robert Johnson III · 12-16-2018, 07:29 AM

Just in case.... Try flipping the phase, see if the track null? Small possibility it is more of a visual glitch.

rin99er · 12-16-2018, 07:38 AM

They cancel each other out, but not the whole time

bezusheist · 12-16-2018, 07:54 AM

Try checking box in snap/grid settings > "snap to project sample rate"
also may need to:
check box in project settings > "force project tempo/time signature changes to occur on whole samples

rin99er · 12-16-2018, 09:24 AM

I tried your tips with the sample rate, but neither one or the other worked, nor dis the combination

I really hope (and think) it‘s just something like that „simple“ - change 1 setting and the issue is gone

nocturn · 10-13-2019, 01:38 PM

i had/have the same problem, i never figured it out, but just then, reaper added "duplicate" and i just started using that.

if you want to go the rendering to track route, "sws: set render speed to real time" first. that way you hear it while its rendering and you can be sure theres no changes.

also bounce "save live output to disk" and mpl's "conditional bounce in place".

all just work arounds, reaper has MAJOR issues with rendering and sync...i think a lot of people are deaf or careless cause ive pressed this issue before and come out looking crazy. but welcome to reaper, save your config often, autosave set to 3mins, always check "project settings" render options (like switching to mp3. screensets ended up walking around that, but i have to load it everytime i load reaper, the most frustrating but equally addictive daw. sometimes, its magic
