    Hi Everyone

    I am a very happy LiveProfessor user but yesterday I I had a huge problem with the software. I am using LP2 as a plugin host for a Musical Production and as my new MacBook Pro arrived this week I switched my old one (MBP2012) out for it. (Even though everything was the same, probably not a good Idea right before the show, Soundcheck was LP bypassed). In the first scene everyone could hear digitally breaking up vocals and instruments. Unfortunately, I have not had the time to look at the DSP display bypassing everything. For the second half I could successfully try out one chain with plug ins again , why I do not know (Plugins as Inserts were only bypassed in the Mixer not in LP). Does anyone have a clue why LP and my MacBook are behaving so wierdly?

    your help would be very much appreciated as tonight is the next show.

     

    (Specs:

    LP2.2.2

    MacBook Pro 2018, i7 Quad Core, 16gb Ram, High Sierre 10.13.6

    multiple UAD Plugins via UAD Satellite, FabFilter Q, Waves FDBK

    64sample buffer≈50-55% DSP, I think I changed it for the second act to 256samples buffer≈45-50%, as I am monitoring the Programm today there are sometimes high spikes even though DSP is very low.

     

    old. MBP 2012, i7 Duo Core, 8gb Ram, SSD, LP2.2.2 512 samples buffer DSP 55-65% no artefacts)

    Hi

    I’m sorry to hear about this.

    First, I think you should switch to the working system during shows until this is figured out.

    I have not heard that there should be a problem with the 2018 machines. I run LiveProfessor on a Mac Book Pro 15″ 2017 model. I will have to see if I can get my hands on a 2018 machine to try to reproduce the problem.
    Also, we would need to figure out if there are big differences on the 2017 and 2018 model.

    What sound device are you using with the mac?

    Also maybe try to run some tests to make sure it is not a UAD problem, try to create a new project with only fab-filter / waves plugins?

    If anyone else has experience with these machines please do pitch in.

    Could this be related?

    https://thenextweb.com/apple/2018/08/10/apple-runs-into-another-embarrassing-issue-with-the-new-macbook-pro/

    The 2018 machine also seems to have heat issues. Apple solved this by turning CPU speed up and down. not great for us trying to process audio consistently.

    thanks for the super quick response,…

    As we are not using the laptop speakers I do not think this would be the issue. We are using a Dante system with a RedNet Pie Card as sound device. I will try disabling the UAD plugins. Thank you

    ok I sound checked with the system again, and it seems the DSP spikes and disruptive sound problems only appear when LiveProfessor is not the application in front. Is there an easy fix for this?

    I am sorry to have related this to LP2. As I just realized Qlab has the dame problem when the application it is not on top.

    I will bother the apple forum, a fix though would be very much appreciated

    I am trying to specify this problem as good as I can so here is an other post:

    Thinking I knew how to avoid the problem I ran the show on the new macBook today anyway. In deed the devastating Crackle could be avoided by either keeping Qlab or LP2 on top. Anyhow I noticed some light crackling sometimes even though LiveProfessor was selected. (Having had a lot of experience driving the old MacBook to the DSP limits) It was exactly the same noise, though less often, as the LP out of CPU power noise before,.. (DSP was at 30%, iStat CPU very little usage, especially 2nd to 4th core).

    Hi

    The reason I thought the “internal speaker issue” was related, is that it seems to be a software issue, as rebooting etc helps users.
    so if it is something wrong with Core Audio it will affect all audio.

    Try to kill App Napp like this:

    LiveProfessor
