Hi. I am in a Band of 6 folks, based in Scotland, who have been using JamKazam for about 4 months with reasonable success, including doing gigs online. 
Recently there have been a number of software updates, some of which have caused ripples.
Our latest challenge however, is that one of our members has relocated to her flat, which has a new router, and while she can connect to one other player, audio is dropped to all others , with 'packet receiving error' messages displayed. What to do given an error message which gives no forward direction?
There has been a lot of discussion across the forums of configuration approaches.  JK obviously supports a number of routes. Legacy information from videos and the forums does not necessarily hold true now.

There may be a Firewall to block port access in the router, or within the PC/Mac, (or both or neither) with specific application permissions or blanket policies.

It would help if someone could describe what JK needs, in one place, for lightly technical folks! Do the following statements hold true?

Router setup can use any of:

• UPNP - this seems the default, as most PCs and routers in our group have not gone anywhere near port forwarding.
  
• port forwarding - UDP works best, in a range of about 10 ports from , for example 12000.  
  
• Single port NAT ?
  

Good evening.  JamKazam has been my musical lifeline during these "unprecedented times". I've practiced with others a few times a week without any problems since I first got connected in late March. 

When I opened JK for practice on Sunday there was a required update - no big deal, I've needed to update prior to several sessions over the past couple months & it has never been a problem until now.  Apparently despite zero issues practicing Thur 6/25 the file from the prior update (1.0.3744) has gone completely missing from my computer. 

When I try to install the 1.0.3787 update I get this error message: 
The path 'C:Users\AppData\Local\Temp\JamKazam-1.0.3744.msi' cannot be found. Verify that you have access to this location and try again. or try to find the installation package 'JamKazam-1.0.3744.msi' in a folder from which you can install the product JamKazam 1.0.3744.

I tried deleting the update & downloading/installing again. Same result.

I've tried completely uninstalling JK (& my interface driver because I saw that in someone's post) and running a Registry cleaner in an attempt to start fresh but I can't even fully uninstall due to that same "path" error.

Is there any way for me to start fresh when I've somehow mysteriously lost a prior update/install?

After a couple days of frustration I am at wit's end and would appreciate any help that I can get!

There are lots of distorted crackling noises when playing the JamTracks

Using Windows 10 with a Focusrite Scarlett Solo 3rd generation.

I don't get this problem playng back spotify or youtube videos, it's only with the JamTrack. On my own n a solo session. I played some sessions with other musicans (without JamTrack) and the audio seemed OK then).

I have the framesize set to "1ms experimental", I changed it to "2ms experimental" and the crackles seems to go away. But then the audio latency increases from 4.5ms to 7.5ms.

I am new to Jamkazam ...and not a network genius.  But I have tried all the suggestions that I find on these forums for the problem of not being to join a session and hear others.  I spent all day on this ...and then talking to my ISP.  The only thing I have not tried yet is a static IP address because this late in the day that requires talking to the business office and agreeing to an extra fee.  So it would be tomorrow on that.    But in speaking with tech support ...they asked if I could see video from others in a session ....and I can.  I can also sporadically hear maybe one person off and on.  So the ISP is telling me they do not think it is the need for a static IP or anything else from them.  What are folks thoughts on this ....so far no good for me on using Jamkazam.

I'm jamming with a lead guitarist.  Our internet connection and very low latency is great however when he plays his lead guitar, I hear crackling sound on my end but he doesn't hear it on his end. Help?

Is there any effort to develop an IOS client?  The tech in my iPad Pro is way ahead of my 11 year old iMac.  If so, I could hard wire to the network if 5G wireless is too laggy.

I am very curious to understand EXACTLY how the video of the Barton Strings (the one on the demo video on the JK site) was done.  It appears to be 4K video, flawless sound, zero latency.  Exactly what we are trying to do out here.

It appears that all four are using the exact same set up.  Is that an absolute minimum requirement for this to work?  And, they are using Mac Books--MAC IOS. I have had MUCH better results in Mac IOS; I'm about ready to completely give up on Windows 10.

When I record myself with video, the recording comes out with low volume and lots of distortion (background hissing, etc.).  I have had this same result when I have done test recordings with three of of my colleagues, each in two-person sessions.  When I record without video, recording has more sound presence and no distortion.

My set up is the following:

iMac mid-2017, 32 GB memory, Dual Core Intel i5 processor.
Focusrite Scarlet 2i2 3rd Gen Studio (the bundle with mic and headphones).
Solo Session Stats:  Latency 11.5 ms (yellow).  Input Jitter (.51 ms), Output Jitter (.44 ms), Gear Driver (Core Audio). and Frame Size (2.5 ms)--all of these are green.
I am running the newest JK update from a few days ago.  

I have also used the Blue Yeti with the iMac and have similar stats and exactly the same recording issues.  

FYI--Blue Yeti does not work in Windows 10 on JK--stats are off the charts in the red at all time, no matter what.

If JK is broadcasting live performances over YouTube/Facebook--as it appears they are--most of us simply do not have all of the info we need to get this dialed in.

One of the local orchestras with which I perform would LOVE to have us do live performances, including video, from small chamber groups drawn from the orchestra.  Can anyone step up with enough information in one place to help me get this done?  Is there any hope that the next update announced in the email from a week ago will do anything to resolve this?

Thank you!

Hi,

We are a three-piece and having repeated problems while playing together in sessions. Essentially this happens:
> We start playing a song together, all is fine
> After a while - maybe 2 minutes - the drummer suddenly can't hear me any more - my signal just cuts off for him
> Guitarist can hear me fine, and I can hear him
> Drummer and the guitarist can hear each other fine
> I can hear the drummer fine
> But he can't hear me

We have discovered that if either he or I do a Resync the problem is fixed, but we can't keep doing that mid-song. It's getting really annoying.

I would attribute this to some random glitch except that it keeps happening, and it's always as above - every link works except the drummer suddenly can't hear me. It happened abut 6 times in a hour this morning, but it has also happened in our last 2 sessions.

Any suggestions on what is happening here would be much appreciated.

Thanks

I've see a few threads talking about distortion, and it seems the replies are implying a problem with audio levels. So I thought a thread for ideas on this problem and how to correct it was appropriate.

Some background; I've been involved with audio engineering and recording (analog and hardware digital recorders) for some time and have a few digital consoles but I have not really entered the full on ProTools world of complete computer based recording. Hopefully that gives a basis for the accuracy of my descriptions of this problem, especially in reference to typical 'digital distortion' due to improperly set gain structure or not understanding How 0 dbu differs with analog vs digital audio signals.

We run band JamKazam rehearsal sessions between 5 people sometimes for few hours, each using an audio interface for vocals and their instrument, and have been doing this for quite a few months. Occasionally, one person will complaint of 'static' or 'distortion', including me. By 'occasionally' I mean the signal between us is good, clean, and low latency but then the 'static' will happen for anywhere from a few seconds to someone needing to leave the session, reboot their setup and rejoin the session. 

What we noticed was people using Behringer interfaces had no problems. We tried an older Focusrite Scarlet Solo, Focusrite 2i2 Gen3, and both and Allen & Heath QU16 and SQ5 digital mixers' interface functions. All except the Behringer hardware interfaces give that occasional distorted 'static'. Further details of out setup is hardwired Ethernet connections (of course), Windows computers all running 10, but some desktops and some laptops, typical total latency between members is 30ms or less, though we see 'red' indications for internet and I/O jitter occasionally. We are all using The manufacturers' ASIO drivers, and the sample buffer is forced by JamKazam to the lowest possible value available, which is 6ms I think. When we try to change it to, say, 32ms, JamKazam changes it back to the lowest setting within seconds.

We all now use Behringer interfaces, from the cheapest UM2 to the UMC1820 and we have not had any 'static' issues since. But I would rather use the QU16 as my interface if not for the 'static' problem.I've investigated USB signal jitter reducers and re-clockers, but I am not sure that is the problem. 

Has anyone has similar experiences and, if so, how did you solve it? Would LOVE if a JamKazam programmer could chime in with the technical perspective of the cause. 

Thanks!

My friend and I just started using JamKazam. We both have UMC 202 devices, successfully set up. I have a Windows laptop with downloaded UMC Driver, she has a MAC using built-in MAC drivers. We have tried several sessions together, and while can connect and hear (and chat, etc) - the music (even just one line input guitar) is unusable. It has significant latency and also some noise. We can each record separately locally through JamKazam on our own gear and that works fine. 

While our Audio latency is generally green (occasionally a bit yellow)  ---  It Seems our network latency is "red" ( around 36-40 ms). 

We have both run speedtest and have upwards of 80Mbps download, and about 10 Mbps Upload, from ewach of our Cable modem based providers respectively.

We have tried setting different output bit rates, and frame sizes - none of which has helped.

Even just one DI guitar is noticeably latent & distorted when heard at the other end of the network. Recordings clearly show this

What to do?

Thanks for your help,

Jared
