    iirc before the load balancing feature, a single audio track would be processed on a single core, so all plugs on that track would also be processed on that core... the lb allows better distribution (in the diagram) but there are a couple of exceptions, like the master bus, and the gui...

    Okay, thanks @pwalpwal

     

    I came across this image on my hard disk a minute ago, taken back in 2013 when load balancing really was an issue LOL :D

    If the audio interface is one of the better makes, the safety-buffer will be small and round-trip latency will be ~5-6ms.

    Yeah, I have been wondering if I made a mistake going for Roland's OCTA-CAPTURE. I mean, you would thing that Roland would make quality gear but my best RTL at 64 samples is 9.5ms.

    But there is no way I can run with that setting and I have to go up to 384 samples giving me a RTL of 34.8ms

    Not that I am complaining as I seem to be able to manage at that. I just get a bit envious when I see guys saying they can get down to 64 samples haha! :D

    You can also try disabling Plug in load balancing in preferences. Ive done it from time to time.

    Hi again @Chuck E Baby :)

    I had a look at this. It wasn't enable for some reason. Not sure if it made a big difference.

    On the help page it shows this image:-

    NewFeatures.017.1.png

    Not sure what this means to be honest. Taking the image at face value it seems to suggest that if you have an FX bin with 8 effects, as show, they are distributed across the CPU cores, as show.

    But what if each of your FX bins only has 1, 2 or 3 effects in them. Does that mean that they are only distributed across cores 1, 2, 3?

    Or does it distribute effects across all the FX bins to each of the core. For example, say track 1 has 3 effects in the FX bin, track 2 has 3 effects in the track bin, will those effects be distributed across cores 1 to 6 in turn? Not sure if I put that across correctly.

    I wonder if this is something that @Noel Borthwick could shed some light on, assuming no one else can?

    it was fine for the officey internetty stuff but rubbish for leisure activities :D

    Know what you mean...

    I installed it on an old laptop which originally had Windows XP on it. It was slowly grinding to a halt. So I wiped it and installed Ubuntu on it and gave it a new lease of life. Great for interwebs and e-mail stuff :)

    I think I ran Gimp on it too...

    I tried this a few years ago, but came back to windows because of VSTs and games 🙄

    Yeah, I'm not saying this is a workable option right now.

    I also looked at Linux a couple of years ago and, for the same reasons as you, I never bothered. I check about every year or so, see how things are going on the DAW side...


  6. I used to have a vinyl that was an hour long.

    It was called the "Golden Hour of the Planets," although, to make up the hour there were a couple of tracks by Sibelius on it.

    So, limiting albums to around 45 minutes has nothing to do with it being released on vinyl.

    I know that the "Red Book" standard length of CDs was 74 minutes but I don't think even that was fixed. Reading the article about it reckons some CDs were 80 minutes long:-

    One thing I know I have to try, once I get my motivation back, is go back to just one OCTA-CAPTURE. Could be that connecting the two units together via a USB hub isn't such a great idea, regardless of what it says in the OCTA-CAPTURE manual.

    I have just tried this and although the delay appears to be a little bit more consistent, at 200ms delay it is driving me around the bend and I just can't work with it.

    I might as well reinstate my second OCTA-CAPTURE now using the USB hub.

    Chances are the effects unit's latency varies depending on its settings. This could prove challenging when using it as an external insert.

    Yeah, I think you're right @scook :)

    They are turning out to be simply not worth the hassle, not how I want to use them anyway. I could still use them along with the modular, I think, and go into them and then onto my audio interface.

    Again, software appears to be winning here... If I had a proper mixing desk, with real inserts and what have you then I'd be good to go, but trying to go through the OCTA-CAPTURE units, and the laptop/Cakewalk, is turning out to be too problematic...

  9. Hiya Tim ( @Starise) :)

    19 minutes ago, Starise said:

    I guess it all depends on your main objectives Andy.

    Well, the intention was to use everything I have at my disposal, both hardware and software. List is above in one of them posts.

    I could still carry on what I was doing which was some ITB stuff and every now and then some modular stuff. Or I could record a modular session and then add to it using software synths and hardware synths. I guess if I was more proficient at actually playing keyboards I would simply record a live take and do away with MIDI altogether.

    22 minutes ago, Starise said:

    Are you using hardware synths as well? 

    Yes, I have two VA synths from the early 2000's and a drum synth.

    To be honest, any of my software synths knock them into a cocked hat in terms of sound and capabilities but it is a real shame to have them sat there gathering dust.

     

    cheers mate, and thanks for dropping by :)

  10. For reasons not worth mentioning here I had ditched Studio One (which I switched to after the demise of Cakewalk) and started using REAPER. I have become reasonably happy with its setup and got past that point of trying to get it to look and feel right to work with. I worked up a project that would become a template. Things were going okay, but then I realised that I was having a problem with synchronising stuff. Although it is possible to apply delay to MIDI hardware outputs I have been unable to get stuff into line. REAPER doesn't seem to be well supported in this way. I have found some articles about the issue and there may even be some workable solutions but I decided to try Cakewalk by Bandlab because I recall being able to set timing offsets on a per track basis.

    Again, things were going okay. I created a couple of MIDI sequences that drive my MIDI hardware synths. I created a VST drum track which was there mainly for checking timing. It is possible to set offset times to the hardware MIDI tracks so that they synchronise with the VST MIDI tracks. I realised that I should have started with synchronising the Beatstep Pro first, though, and had to adjust everything else to suit that. There doesn't seem to be a way to create an offset to the MIDI clock out of a particular device output. So I had to adjust timing offsets again, but it was reasonably quick to do.

    I have two outboard effects units. A Line 6 HX Effects, essentially a guitar effects unit, but it is also a great multi-effects box. And a Lexicon MPX 500.

    I figured out that I need to create a couple of new stereo busses and in their FX bins insert the External Insert VST that comes with Cakewalk.

    And now to the seemingly unsolvable problem...

    As soon as I added a send to the HX Effects bus and started playing the project nothing at all was in sync anymore. Further to that, I could adjust the timing offsets to suit the new audio delay, but the delay is inconsistent and all over the place. If I disable the outboard effect or remove the send then the timing settles down again.

    I am at a loss as to what to do next to be honest.

    One thing I know I have to try, once I get my motivation back, is go back to just one OCTA-CAPTURE. Could be that connecting the two units together via a USB hub isn't such a great idea, regardless of what it says in the OCTA-CAPTURE manual.

    I could also try plugging all the various USB hardware into different ports, see if that helps.

    Another thing that springs to mind, and would be something I could check pretty quickly, is remove the outgoing clock signal to the ports that synchronise the tempo of the two effects unit. It felt like a good idea at the time to have the DAW setting effects tempo instead of editing the effect preset to suit each project tempo.

    I have been running some tests with LatencyMon and the Centrance ASIO Latency Test Utility. Early days on that, though, and I need to carry out more tests and then try to interpret the results. First impression is that all is well in terms of the capabilities of my laptop but there are issues and I am not sure if they are real issues or things that do not matter with respect to duplex audio.

    Other things to try would require quite a bit of cash to do. Such as replacing my old laptop for starters, and perhaps even going back to a desktop which would have a greater amount of USB connections. Or even consider a PCIe audio interface.

    So much to think about, and none of it conducive to actually creating sonic soundscapes!


    Thank you very much for getting this far. I appreciate your time.

    cheers

  11. A brief history in time: And into the Future...

    Back in the late nineties and into the early naughties I developed a studio setup based on hardware synths and effects which were all connected to a 12 channel mixer. I used Cakewalk back then, with no audio capabilities to drive my MIDI gear and used Sound Forge to record a final stereo WAV file.

    Still in the early naughties I joined a real band. That took up most of my time, musically, and my gear gathered dust.

    In the mid naughties I attempted to get back into doing my own stuff again. By this time SONAR 5 was on the scene and I decided to upgrade to that. So much of a jump for me, in fact, that I paid full price for the Studio edition. I was still using my hardware stuff at this time but recording now into SONAR as individual tracks. I had, by this time, treated myself to a 16 channel MIDI mixer that had ADAT capabilities and an RME soundcard which also had ADAT.

    Another hiatus followed and it wasn't until the summer of 2012 that I took the opportunity to upgrade to SONAR X1 Producer. And at the same time I purchased my current laptop.

    By this time I had dismantled my hardware studio and I decided to go down the route of using software synths and effects. And a productive and interesting journey that has been.

    Every now and then, though, I think, "I really should dust off the old JP-8000 and see if I can do something with it." And I did, for a time. My studio location changed, at the behest of SWMBO and stuff got put away again.

    Then a couple of years ago my son and I watched the "I Dream of Wires" documentary and it wasn't long before we had built up a nice little modular system.

    Shortly after that I was given permission to take over one of the spare bedrooms, now that our offspring had fled the coup. The hardware was dusted off and slowly but surely I started to make use of it. Not as much as what I would have liked and I still gravitated to ITB stuff. The modular system would sometimes take centre stage and the older MIDI stuff would be sat there doing nothing. And then I'd be back doing software stuff.

    My latest acquisition was a second Roland OCTA-CAPTURE with a view to increasing the number of audio inputs and thereby allowing me to start looking at bringing all the pieces of my studio into play. I'm not a great instrumentalist and therefore I intend to utilise MIDI for the hardware that is capable and the Beatstep Pro will act as a link to the MIDI stuff as well as being a hardware sequencer. Early experiments synchronising the MIDI equipment with the modular system went quite well.

    So, my dream of being able to compose "music" using a combination of VST instruments and effects, MIDI hardware synths, hardware effects and the modular setup was starting to take shape.

    It seems, however, that I have bitten off more than I can chew... That the dream is, unfortunately, struggling to become a reality.


  12. Okay, so first of all I will expand upon my current studio set-up.

    My laptop is a CLEVO P150EM consisting of an Intel Core™i7-3820QM Quad Core Mobile Processor 2.70GHz 8MB cache, Intel HM77 Express Chipset, 16GB SAMSUNG 1600MHz SODIMM DDR3 RAM, NVIDIA GeForce GTX 675M - 2.0GB DDR5 Video RAM, 500GB Samsung 850 Pro SSD and a 1TB Samsung 850 Pro SSD.

    Audio Interface consists of two OCTA-CAPTURE units with one in "expansion" mode which gives me a total of 16 audio inputs and a stereo digital input. Each unit has MIDI in/out. The documentation for the OCTA-CAPTURE recommends that they are connected to the same USB controller, and, if that is not possible, to use a USB hub. I have opted for the hub because I have a limited amount of USB ports on my laptop.

    I have a Roland MMP-2, a mic pre, which has SPDIF out and I connect that to the OCTA-CAPTURE stereo digital input to give me a total of analogue 18 audio inputs.

    Further MIDI connections are provided by a MOTU micro lite MIDI I/O USB device (connected to PC) which gives me an extra 5 MIDI in/out connections.

    I have an Oberheim OB-12 VA synth which has MIDI in/out (problematic in that for some reason I can only switch banks using SYSEX). I take a mono audio out from this.

    I have a Novation NOVA VA synth which has MIDI in/out/thru. I take a mono audio out from this.

    Alesis DM5 drum synth which has MIDI in/out(thru). I take a stereo out from this.

    Arturia MINIBRUTE analogue mono synth. This has both MIDI and CV/Gate connections but I choose to "play" it via MIDI. A mono synth so just one audio out.

    Arturia Beatstep Pro hardware sequencer has MIDI in/out as well as CV/Gate and I use this in slave mode, sync'd via MIDI from #1 OCTA-CAPTURE. I use the Beatstep Pro to then clock various things on my modular system.

    Modular system - I take up to eight audio outputs from this.

    Line 6 HX Effects outboard effects unit (guitar pedal). I connect the USB to the PC and can sync the tempo in the DAW via MIDI. I use this as a send effect and therefore I have to use a suitable VST to direct audio to a pair of outputs on the O-C and then back in to a pair of inputs. I can also use MIDI to select presets.

    Lexicon MPX 500 outboard effects unit. I connect the MPX 500 to one of the O-C via MIDI in order to sync tempo. As per the HX Effects unit I use a suitable VST to route audio back and forth. I also use MIDI to select presets.

    DAW wise I have licenses for REAPER and Studio One 3. Cakewalk by Bandlab is also installed.


    I'm sure there are larger studio setups on the planet. What makes this particular setup a challenge is what I am trying to do with it. More of that next.


  13. This is going to be a potentially long post, but I shall first of all post a TL;DR version here just to give you a flavour.

    Recently I have been spending some of my hard earned cash on new music gear and software.

    Just as a hobby, mind, I ain't no pro...

    Anyway, to cut a long story short, due to ongoing issues with what could be either software or hardware, or both, I am having to take a step back and weigh up my options. Hence, the pragmatic approach.

    I had hoped that I could combine my love of software and hardware into one project, using a DAW that could do everything I needed it to. In the end it seems that what I am trying to achieve is simply not possible.

    I could throw more money at it. However, I am currently not earning a crust and so I seriously have to address my past spending habits.

    I will return to using mainly software for my creations but will incorporate my hardware where and how ever possible.

    Perhaps in the future, when I have the funds, I will investigate replacing some of my current hardware. I should add, in defence of that hardware, my laptop has been a great tool and it is only now that it seems to be letting the side down. As an "in the box" sound design tool I am sure that it will give me another five years service.

    I will follow up this post with further details of my desires, set-up, and problems encountered. You never know, someone might say, "hey, you can simply do this!" Or, "yeah, there's no way that that idea will ever fly."


    cheers, and thank you for getting this far,

    @synkrotronNot wishing to sound condescending but you are in high performance mode, yes? I'm just looking at that Adaptiverb on what sounds like a VSTi track on a somewhat aging mobile CPU, so not being in high performance mode is a bad idea as Zynaptiq plugins can get pretty intense pretty quickly.

    Spiking one core is obviously loading one core too heavily, so if you've got the verb as an insert on a demanding VSTi with (hopefully not) a bunch of other inserts on the track as well then that's something you could look into. Run the output of the VSTi to a bus, then load that bus with the plugins. Split the verb off to a send as well so it's not on the bus. Try increasing your buffer.

    Be aware that you might be asking too much; many modern plugins are getting pretty demanding.

    Hi @ien :)

    Yes, I am running my laptop in high performance mode.

    I've been using Adaptiverb for some time now, well, since it was released, and I am aware of its demands and work around that. My project right now is very small, in terms of VST and VSTi and Adaptiverb, although CPU hungry, doesn't usually present any problems.

    cheers, and thanks,

    So many variables! I would think "Adjust for best performance of: Programs" would be the choice. Mine is set there and I've never had audio issues.

    Also in that window is the paging file size (virtual memory). Mine is set to auto manage but in the past (pre Win10) I've always set it to a permanent size as I didn't like Windows messing with it. Now I run 16 GB of ram and don't have any huge audio projects so for me probably not an issue. Core meter never hits over 25% and mostly stays just barely visible.

    Hi @sjoens :)

    Okay, a bit at loggerheads with @Sailor55's post, so I will just have to run with both and see what works best for me.

    Memory wise I also have 16GB of RAM. My paging file size is set to a fixed 1GB.

    cheers

    Here's the one suggestion that seemed to make all the difference for me:

    3. Set processor scheduling to "Background services"

    Thanks @Sailor55

    I am sure that I had already done this but I often forget to check the more subtle settings after big windows updates, which have a habit of returning settings to default. I've switched it back as you suggested but I have not yet found the time to check out if it helps.

    cheers

    FWIW, If the machine is having issues such as high DPC Latency, it doesn't matter what DAW software/plugins you're running (all with be negatively affected).

     

    BTW, Unplugging the LAN port disconnects from the Internet... but it doesn't actually disable the LAN controller.

    ie:  If the LAN controller's driver is causing high DPC Latency, simply unplugging the LAN port won't resolve it.

    You can update/roll-back the LAN driver... or disable it (Device Manager or motherboard's BIOS) while working with audio.

    Thanks for input, Jim, much appreciated.

    As I have sort of suggested above, CPU core balancing now appears to be my least concern. I don't want to go into too much details in this post. I am in the process of drafting a new post with regards to my complete setup, dreams and wishes and all that. I will also be posting my LatencyMon reports and screenshots. Not great reading but, surprisingly, DPC seems to be "reasonable."

    And you are right in that, it doesn't matter which DAW I am using. The big "but" here is, in all my years of posting in various forums, the Cakewalk/SONAR community has always been the biggest help.

    cheers, and thanks again,

    andy :)

  18. Thanks for your input @Shayne White :)

    Okay, perhaps I need to try the other settings for ThreadSchedulingModel, see what happens.

    To be honest, after last night's "problems," I am losing interest in achieving my goals, regardless of which DAW I am trying. CPU core balancing appears to be the least of my worries.

    I've had LatencyMon for some time now. I've been using it to look at things in the last couple of days. Not sure how to deal with the results. You mention WiFi, and that does seem to cause some "issues," as does my wired network. If I disable all network stuff the associated drivers no longer figure.

    I'm going to try a few more things today and I will probably post another topic once done. Like I said, CPU issues may not be the problem in the grand scheme of things.

    cheers
