How to compensate latency when sampling external gear?

    When I sample (sampling mode = sync) an external synth which is played by Maschine (standalone), I got a small gap (around 10 ms) at the start of the sample. I think this is caused by latency. I've tried to compensate that with the Sync Offset Slave and Clock Offset settings, but without success. It's not a big deal to remove the gap using the Edit tab - but this way is a no go with loop samples. Any ideas for a workaround or setting?

    i haven't had this problem at all... what are your latency settings?

    I also have this problem, but the latency is higher. It looks like it is the overal latency. Even when I record the Maschine metronome click through my Soundcard(Korg Zero8) the sample loop is offset and there is a gap.

    I have had this problem the first time very long ago and I am quite sure that it was away for some time , but the last weeks or months ist makes most of my sampled loops unusable.

    This problem also happens when I use Maschine as VST FX plugin in Cubase SX 3.

    There is more troubleshooting than making music for me this and also the last year :-( I hope the next year will be better. It's not mainly with Maschine - all my gear seems to hate me, and Maschine has a quite good feature - problem ratio ;-)

    I don't think that is latency I think that is a bad sync.

    So Maschines metronome is in bad sync with Maschine ? No ;-) Even when I sample the Metronome it is offset. Everything is in pefect sync, the resulting sample loops are not.

    That could be a number of things.

    1) You're going to have a couple ms from your audio interface, no matter what
    2) What hardware? How many notes? Hardware synths need time to turn on voices, and some more than most. And, the time between first and last note ons with chords can be substantial.

    1) This input latency usually should be compensated by the recording software. For example in the Cubase options latency compensation can be dis- or enabled. But the offset in my Maschine loops is much bigger than only the recording latency.

    2) My soundcard is a Korg Zero 8. No notes - I have this problem even with an empty project when I record just the Maschine metronome click through a Zero 8 channel. Even this click has a very long offset of about 50ms. No matter if I record the metronome, a synth or guitar, everything is out of time in the same way. When I sample from internal source, everything is perfect in time.

    When it would have to do with my synths I would hear the offset before sampling.

    But I am quite sure I did not always have this problem. First I realised it when testing the first 1.50 beta.


    Thanks for help to all,

    Same problem here:

    It is impossible to sample the soundcard inputs without a gap of some milliseconds before the beginning of the recorded sound (in sync mode).

    This is a serious problem!

    The software should have at least a slider where the user can adjust the offset that is done AFTER the recording.

    In ableton live for example there is the same problem, but the problem is gone when you select "off" at the channels monitor input routing. In this case there IS a recording compensation that moves your fresh recorded audio material to the right start AFTER RECORDING.

    Ah ! I'm glad to see people with the same problem like me ;-)

    I think it is not important if the offset is compensated after recording or before - I just want to record with the same timing as I am hearing while recording.

    But for the slicing stuff this slider might be quite elegant and helpful, so why not :)

    But please, solve this problem, VST support and timestretch are nice features, but I consider this one as a major problem, because one of the main functions is not working correctly ...


    I have attached a screenshot of the lagged metronome recording.


    Merry Christmas !

    In ableton live the argumentation for not correcting the offset in input monitor IN or AUTO mode is, that the musician has to play before the actually heared tone- he corrects the latency by himself.

    But in case of sampling this makes no sense. There has to be a correction!

    Maybe there is a correction in the maschine software because the overall latency is shown in the audio settings. But I think it simply won´t work with every audio gear available.

    THIS HAS TO BE CORRECTED!

    I have spent some time recording my metronome click and reduced the latency. The gap is smaller now and first I thought it would be usable now. But the gap still has the size of the overall latency. The offset exists on every externally sampled loop and everything was perfect in sync while sampling. The resulting loops are still of limited usability :-(

    Hope it helps you. I would be really happy if someone could check this issue by connecting the soundcard in and out and recording the metronome click.

    Best regards,
    DerDahli

    Great screenshot. A picture says more than thousand words ;-) I think betatesting the 1.6 is a good way to report this issue.

    and also saying exactly what your system is ;)

    Glad this came up. I've had this same problem since I bought maschine. anytime I sample from external gear or a different sound card feeding into maschine and sample, I get a gap at the beginning of the sample.

    PC, xp/win7, m-audio and rme fireface 800. Laptop with RME Cardbus interface feeding sounds into maschine for sampling produces the same problem. I hope v1.6 fixes this. I thought it might well have to do with how maschine handles latency than sync. Reason 5 running on a laptop and sampling into my desktop workstation running maschine creates this same problem.

    Please look into what is causing this and correct it. Thanks

    one of you guys need to list this as a feature request in the Feature Suggestions Sub-Forum.

    personally, this is not an issue for me on my Mac

    I have created a thread in the feature suggestions section:

    http://www.native-instruments.com/forum/showthread.php?t=127374

    I have attached the screenshot and my system specs. I guess we will soon get rid of this little nasty issue :)

    On the Mac the problem does not exist ? That's interesting. I am just glad it is not only my setup causing this problem, so it looks like one of the problems that easily will be solved by a Maschine update.

    okay, you Mac guys need to give more details about your system and what you are doing.

    so....what are you sampling, how are you sampling?

    also give details of your Mac.

    i know in the past, Mac users have said there are latency issues when you use Soundflower... i just presumed that was to with Soundflower.

    to be honest, i have not done much external sampling into Maschine and have not done it for a while, as i prefer to record into Logic and then edit the waves there.

    so yes, i look forward to reading about your sampling scenarions :)
