I've been using JK regularly for over 4 years, always with the same equipment that I have now. It took a lot of fidgeting and experimenting with settings to arrive at a good configuration of the app and my audio interface driver but once I got it (4.3ms audio interface latency, jitter saw-toothing between 0 and 0.53ms) it's all been fine for years. I never installed the long-term beta release but just stayed on the prior release.

Fast-forward to yesterday, when I was forced to install the new update: 

First off, my audio settings were gone. Not a big deal, I went through the "add audio gear" screens.

When I started a private session to test it, I was getting all kinds of jitter - hovering over my 'dot' showed high jitter numbers and I heard a lot of crackling. Adjusting the frame size larger did nothing but add more latency. I doubled and triple checked all my driver settings, and even tried different buffer sizes, sample rates, etc. Same thing.

During one of my testing iterations I noticed something: when my session first started, in the first few moments where you can hear yourself but before your "input" and "output" mixes appear, all sounded fine. As soon as the UI filled in that information with the audio bar graphs the jitter went crazy. Then I noticed when I moved my mouse past any clickable element on the JK UI I also got a crackle. Ahh, something to do with the graphics maybe. I then minimized the app and my sound returned to normal. When I brought it to the forefront again, the issue returned.

I joined a session with some people I know and they verified that when my UI was active that my sound was garbled and my jitter was off the charts, but when I minimized the app then things were normal. They did notice that my CPU usage was high. Checking in Windows task manager I saw that my CPU was around 61%, almost all of that coming from the JK app.

Then a bell went off: years ago, the prevailing advice was to set the JK process priority to "High" in task manager. I checked and it was still set that way. Changing it to "Normal" lowered my CPU usage to around 40% (still all JK) but my jitter and sound problems went away.

So it appears that the JK UI update is very processor intensive and can weigh down an older machine (I have a Gen 3 Core i5, SSD, 8GB RAM, Windows 10). If you are having similar issues (I know of another Jammer with this jitter issue since update) then you might try the same thing: check your process priority and try a lower priority to see if it corrects your problems  (https://helpdeskgeek.com/windows-10/how-...indows-10/). I doubt JK will look into this (JK's high CPU utilization) so we're on our own here. Maybe my resolution will help you find yours.

I hope this helps.

Hi there:

I am using a Mac computer. Jamkazam recognizes my audio interface and sets up the inputs and outputs correctly. When I select a plug in however, it plays the pre plug in clean signal, rather than the post plug in sound. I should be hearing a distorted guitar sound, but I am hearing a clean guitar sound. Can someone advise as to what the issue may be?

Thank-you for your time and expertise.

 I am able to hear my guitar but for some reason, it does not let me hear the guitar signal post my plug in. I should be hearing a distorted guitar sound, but I am only hear the clean sound. I can see the guitar signal drive the volume meters I=on my plug in, and on the Jam Kazam app, but I don;t hear the distorted signal. 

Advice would be very much appreciated!

Thank-you

Francis

I am not sure if this is a Mac problem, but it may be.

A week ago I received an automatic update to Build 2.0 - 2.0.0.1850, which I am running on a Windows 10 system.  We have had several cases where the application appears to hang, and further investigation determined that the (now unresponsive) app is utilizing 30% of the CPU.  Killing the task and restarting it clears the problem temporarily.  Is anyone else encountering this problem?

Hi, I just updated to Build 2.00 - 2.0.0.1850 as was suggested in an email from Jamkazam. Everything seemed to go ok except I can't get the video to work. It was working fine before.

When I start a session I don't get the "Video System" choice up top. When I look in my account and look at Video gear it says it can't detect a web cams?

The camera is connected and works fine in things like Zoom & FaceTime. In my system preferences it says Jamkazam has access to my camera?

On Jamkazam's website it says that if I'm having trouble with the new version I should download an older version(and gives a link). I did this and when I try to run it it won't let me until I download the latest version.

Anyone have any ideas as to what the problem might be?

Hello - I subscribed to the Gold Plan last week but on the My Account page it says that I'm still on the Free Level. When I try to re-subscribe, I get a box that says "You already have this subscription. No changes were made to your account." When I click the link for Help Desk, I get a message saying that I must be on a paid plan to use support. I sent an email to support and got back the message that they won't respond to my email if I'm not on a plan... Does anyone have a suggestion for next steps? Thanks!

I was using Jamkazam briefly during the early Covid years. Now I'm back because the new band has a guitar player that lives an hour away. I was surfing for ideas on how to improve the audio. Everyone, except the remote guy were complaining. I found Rick F's post. His band was in exactly the same situation in January 2024. Here's the solution they came up with.

"The board operator copied the main mix settings with me included into the individual headphone/monitor sub output settings.
Then muted my input from the main mix of the boards main output which is the input chosen in JamKazam to send to me.
Since I'm no longer in the the main mix sent to me through Jamkazam I no longer hear myself coming back in the mix. Delay/echo gone!"


We're going to try hooking up the same way tonight.

Only detail you didn't mention in the procedure was pulling the fader all the way down in the Personal Mix so only the remote guitar and vocal come through. In fairness you don't do it on your end. The guys at the studio end do that.

Hello. I apologize if someone has already asked this, but I searched the forum and couldn't find it, so here goes.

I'm using a 2i2 and a Mac Mini. In Input 1 I have a dynamic mic; in Input 2 my bass (no patches). 

My buddy is using an identical 2i2 and a MacBook. In Input 1 he has a dynamic mic; in Input 2 his guitar (no patches).

We can join a session together and hear each other through our mics and see each other on video, but neither of us can hear the other's instrument. Switching off Direct Monitoring doesn't change anything. We switched the mic and guitar inputs but still no luck.

Do we need patches? Any other ideas?

Thank you!

I'd like to use the mic on my headphone cord for chat, using a splitter cable to run the mic into my interface input. Looks like I need something like this: https://www.bhphotovideo.com/c/product/1...aptor.html

Has anyone tried this? Does it work?
