And thanks, catsandwich. In a nutshell, this is more or less it.
But from time to time it may make sense to invest a view minutes and restate the usual...
Here we go!
Let's try to keep the thread on topic and also try not to get carried away too much emotionally.
The subject is "sound engine bugs" and therefore we should approach it from a pure technical point of view.
In his first post in this thread rcpunker quoted a mail 3phase posted on another forum with two technical observations/statements he made.
Those made him wonder if they are caused by bugs in the sound engine.
Let's get to it!
i was bouncing from one track to the other from within a group..solos on the group channels..
and this is the result of the phase cancelation test of an ableton internal bounce:
is this for others reproduceable?.. a bassdrum internally bounced should cancel perfectly... only a utility plug set to the left channel involved.
Bouncing and phase canceling a clip that is not altered otherwise should cancel the signal out completely.
If it does not, the files are simply not the same or something undesired happens during the mixing process.
I just tried bouncing and phase canceling again and the result was silence.
This means, the reason might be a wrong setting in the test set (fades, plugins, timing differences) or it might be a bug that only comes up under certain circumstanes.
Regardless of which reason it is, we need more information before we can discuss this further.
In order to give us (and others on the forum) the chance to comment on that technically, we need an exact description of the test and setup, or better, the project file. If there's some kind of error introduced by settings made by the user we will find them this way, and if it is not related to settings but really pointing to a bug, we will find it, too. No need to rant, as soon as we or anybody else can reproduce it at all, let's just find the reason and eliminate it.
The next one is...
Another bug i came along..the brown henke dither bug..
when you change the tempo around..best with the automation draw in the masterchannel... and than type in the original tempo again in the main tempo window.. because you never get back to the original temo by drawing an automaion line..
after going back to original tempo all tracks that was in the so called transparent setting in ableton live..where samplerate conversion is supposed to be off aslong the clip tempo nd projekt tempo match..
All this clips will have samplerate conversion engaged than..
you need to switch warping off and on again on each clip.. than it returns to the transparent setting..
is this an user exclusive bug as ableton wants to make me belive or are others experiancing the same?
its easy to test..when you switch warping on and of on original speed there shouldnt be a difference...
as there shouldnt be a sound difference between 32 bit float daws.. but theorie and praxis... not allways the same thing
In this description he is confusing a few terms and functions, but overall i guess we all get the point.
The general situation is, that besides when using the Complex and Complex pro warp modes, warping will be neutral as long as the clip is running at its original speed.
Regardless if you just never change the tempo, or if you change it and set it back to the original speed, just as explained in the manual:
"Unstretched Beats/Tones/Texture/Re-Pitch Warping
If the tempo of a Clip is the same as the tempo of the Set, that clip will play back unstretched.
In this case, if the Warp mode of the Clip is set to Beats, Tones, Texture or Re-Pitch (but
not Complex), playback will be neutral. Any Warping caused by changing the Set's tempo
is non-permanent, and audio that plays back unwarped at a given tempo will always play
back unwarped at that tempo, even if the tempo is changed and then changed back. For
example, if you've recorded some tracks at 120 BPM, but then decide you'd like to slow
the tempo down to record a particularly difcult solo passage, the original tracks will play
back neutrally again after returning the tempo to 120 BPM. Only the recording made at
the slower tempo will be stretched. Please note that the Global Groove functionality works
by modifying the positions of Warp markers. This means that playback of audio clips with
Global Groove applied will be non-neutral even at the original tempo.
The neutrality of unstretched clip playback is veried by performing cancellation tests on
I just tried it over here (not for the first time ;-)) and i can't reproduce a non-neutral behavior after setting it back to the original tempo.
I encourage everyone to do the same as in an ideal world such threads would be free from rants and just commented by people sharing their results of testing what the first post suggested instead of a heated up discussion.
So, let's get technical!
As always, if you find something in Live you don't understand, regard as a flaw, a bug or whatever - make it as reproducible as possible and send it over to firstname.lastname@example.org
so that we can clear things up for you or fix bugs that might be found that way.
Also feel free to share such tests in the forum to get as many opinions and test scenarios as possible, while keeping it as technical and rant free as possible. This speeds up things a lot and makes the forum more enjoyable for all.
