Hi, new MG user, have so far only worked with the demos. Running a Windows PC with i7 10750 (6 core, 12 thread) CPU, 64 GB RAM, Windows 11, and using a Presonus Studio 24c as an interface. MG2 works great, and I’ve been having a lot of fun with it; however, when using MG3, I get persistent crackle on the output, even using the built-in JX10 synth. Some VSTs are worse than others, of course, but CPU use does not seem to exceed 50% at any time. I have checked all settings both in MG3 and whatever VSTs I’ve tried, including latency, sampling rate (in the interface and MG3), checked for updated drivers, etc. and nothing seems to make a difference. PC is in high-performance mode and multi-threading is enabled. All background programs disabled. Have checked all cords and connections. So I’m stumped. Like I say, MG2 works great, and the computer should be more than capable of handling MG3. Does anyone have suggestions for things I might try? It’s bad enough that it is pretty much unusable at this point. Thank you!
Sorry, forgot to add- this is using the standalone version. I haven’t used the plugin yet.
what sample rate are you using?
do you have crackling if no synth is present (ie: guitar audio output only)?
running latencymon is often helpful in cases like this.
disabling wireless is worth a try.
also try plugging the presonus into another usb port.
lastly there’s a cpu tool which i forget the name of but which will force the cpu to run at 100% power instead of throttling itself down. i’ll try to dig that up.
Thanks for the tips! There is no crackling just running through the interface or through MG3 with no synth. The USB port thing is worth a try too, I have seen where people have issues with USB 3 or Thunderbolt ports. Are you thinking of ThrottleStop? If so, I’ve got it downloaded and will give it a try. I also have latencymon and will take a look. Going to check the version of the interface software too, as well as BIOS updates. Thanks again, I’ll post back with how it goes.
So I plugged the Presonus into the standard C port and things improved a bit (I had only switched it to the other Thunderbolt port before), but I was still getting crackle on some sounds randomly. I then switched it to one of the standard usb-B ports, and pretty much all noise went away and it sounds great. Who’d have thought? Oddly enough, the CPU monitor in MG3 is now at a lower level as well. The only other thing that I can think of was that earlier today while messing with the laptop, I discovered that the two 32GB RAM sticks were in the wrong slots for dual channel mode to work and I switched them to engage dual-channel mode. Whether or not that would matter, I don’t know. Not sure why MG2 would be fine through those other ports while MG3 had issues, but hey, works for me! Thanks so much for the help, greatly appreciated!
Don’t give too much on the CPU meter in MG3 since it does “strange” things. Inserting the sustainer module (or have it as a single insert in a chain) makes it jump up, though nothing is processed at that time and other measurement tools running in the background can also not confirm higher CPU loads at that point.
are you using a usb-c monitor by any chance?
regardless, it could be that your usb-c traffic is heavy while your usb-b is not. or that windows is giving priority to another usb-c device.
in any case, it’s great that it’s working now.
the ram issue probably wasn’t causing crackles, but it is good to have that sorted.
(this is a gentle reminder that it’s a good time of year to image your hard drive.)
Can we assume you’re using an ASIO driver? Try increasing the buffer size.
I didn’t have anything else connected to any C ports, just the interface itself, and MG2 seemed to work fine. I figured the RAM probably didn’t make a difference, but just thought I’d add that detail to be complete. Also, I am using the most current ASIO driver for the Presonus, and adjusting the buffer size was my first step- alas, no difference. It’s got to be the USB port that makes the difference, but I’m not clear on why that would matter. Maybe the USB-C cable itself? If so, then why no issues with MG2? Thanks for all the help!
i really can’t explain why mg2 would be fine when mg3 is crackly.
i do have some usb-c cables which are weird on occasion. have you tried another?
on the guitar side of things deep expressor and sweet spot are fun to play with. and the nams, omg.
It is indeed a mystery. I’ll try some other C cables and see if it changes anything, but that one was brand new. Well, it works now and sounds great- plus, the MPE capability has solved the issue of no bending with Surge, which was an issue with MG2 that I couldn’t overcome. At least I assume it’s the MPE. Tons of fun!
