While working with samples and the Sampler, I found that the identical samples that were dropped into the arranger directly will have some micro desynchronization at random points. I made a short 2-tracks project where the same sample has been used in the sampler and the other directly in the arranger, made the same volume and inverted one of the tracks. Listen to the loop for like 4-5 times. The first or second loop playing might be ok ( silence), then you will hear those “bursts” poping at random points as result of a asynchronization. The problem is not with the Sampler, because I tried the Sampler against the PhasePlant Sampler and they nulled just perfectly.
Hey, it seems like the 02_hit-kick-01 in the sampler is 44.1 Khz 24 bit, and the 02_hit-kick on the track is 48 Khz 64 bit float (which is the project sample rate). Maybe that’s part of the problem. Also, FWIW, I noticed that the artifacts go away when the tempo is 120 bpm or above.
The sample is from the Cubase sample library. (But my intial test was with my own sample that has been sampled from d16 Drumazon 2 and there was the same issue).
So the original Cubase sample was inserted into the arranger (and become a 64bit) and to the Sampler, which kept its original samplerate and bitdepth (44.1k/24bit)
I hope not. My understanding is that it’s supposed to use the project settings–but I haven’t used the sampler in any projects yet. I’ll probably test it later.
I found the earlier post, saying, that it doesn’t do offline conversations, but it is doing it on the fly.
“Correct, the Sampler Track does not convert the file itself, you can verify this by looking at the file in the Pool under Audio > Sampler Track. The Sampler Track, like most other samplers/plugins, performs Sample Rate Conversion (SRC) on playback, in real-time.”
So still I don’t understand which sample drifts in time - in the arranger or in the sampler. I would understand, if there wasn’t silence with every kick hit, but it is totally random.
So I made a new test project, where the sample is the same for the Arranger and the sampler (48k, 64bit). And it has the same issue (please play a loop a few times). So it is not about sample rates and bitdepth!
Then, instead of using the Steinberg Sampler, I used the PhasePlant sampler and the arranger against each other. And the drift was still there! Then I tried the Steinberg Sampler and PhasePlant Sampler against each other and it was PERFECT NULL!
So the problem is with the arranger handling the audio.
The sample for the sampler track was missing from the audio folder, so I couldn’t test it–but I duplicated the top audio track and inverted phase on the copy. It nulls fine at every tempo. It seems like there’s nothing wrong with the audio handling (internally, at least) but I couldn’t get two sampler tracks to null with inverted samples. It seems to me that the issue is with the sampler.
Yeah, If you use just the arranger and invert the phase of one of them, it will null. I never said it won’t. But load that same sample into the sampler and the other leave in the arranger, then invert the phase and volume much till the silence and it will start desyncronizing pretty fast. Make a longer loop (2 Bars) and it will get bad by the third cycle.
I’m not 100% sure that it is the sampler fault. Because if I use Steinberg Sampler and PhasePlant sampler and invert one of them and volume much till silence, then there won’t be any desynchronization, just an endless null.
It is fine when I duplicate the the sampler and invert the phase. Duplicate the sampler when the sample has already loaded. I used the phase invertor in the Pre-Section. Don’t use any plugins. And make sure to not duplicate the phase inversion.
