Exclamation Network PORT specs?
Posted by: csfuser - 04-26-2020, 05:24 PM - Forum: Help with Network Gear - Replies (5)

I'm new to JK, but no stranger to networking, remote apps, etc.
I've done some research on the interweb and forums, and I know the team is buried with all the recent activity, but...

Can someone from the JK team please "sticky" which ports [UDP/TCP] are used by the JK client(s) so I can open them on my firewall?

I won't arbitrarily open up UPNP on my network for security reasons. 
I'd prefer to implement port forwarding firewall rules to specific local client IP's, so I need to know which ports to forward!
I see 12000-12010 on other threads...  are these still correct?

Viewing active TCP ports I see:
JK using UDP 56192 - 62337 local
JK using TCP 6767 remote to nodebalancer!
It's also uses http/https calls to AWS and other "sites"..

I have a fast 300/50 (mbps) connection, yet most of the JK clients in sessions show as poor, fair or unacceptable. 
I have a public IP from ISP, and IPv6 is NOT enabled on my network!

I'd like to explore the app potential, but "no audio" and poor connection quality (again, assuming due to blocked ports on the firewall) are not helping.

Pls advise, and THANKS in advance.

  Help! Many questions
Posted by: Anik St-Pierre - 04-26-2020, 03:11 PM - Forum: Help with Network Gear - Replies (3)

HELP! Quelqu'un peut m'aider? Mon mari et moi sommes nouveaux sur JK et nous commençons à l'explorer. Voici quelques questions que nous avons: pouvons-nous avoir chacun nos comptes JK et faire nos sessions ensemble en utilisant la même connexion internet? Aussi, à chaque fois que nous voulons faire le Test Network, ça ne fonctionne jamais. Ca nous dit qu'il n'y a pas de serveurs. Pouvons-nous quand même utiliser JK à sa pleine capacité? Y a t-il des conséquences à ne pas faire le Test Network? Aussi, ça griche un peu quand on joue et ça griche constamment quand on ouvre la fenêtre vidéo. Que faire pour que ça ne griche plus? Merci

  "No Audio" - but one-sided
Posted by: AnnRum - 04-26-2020, 01:57 PM - Forum: Help with Live Jamming Sessions - Replies (5)

Hi folks, as with a lot of people, I'm trying to get Jamkazam working for a group of friends who are all isolated for lockdown & have come across a bit of an odd problem & hoping someone can give me some pointers / advice.

I'm all set-up & working ok, I can start a session & other musicians can join & we have full audio etc. If my Dad starts a session - I get the "no audio" showing against him when I join. He can join my sessions just fine & I can hear him.

From what I can tell, this is something related to router settings - but whose router? His or mine?

We're both fairly tech literate, but some of our friends that we want to get online are not so tech literate, so any basic level advice in getting people set up and configured would be really appreciated. The group is mostly acoustic guitars and singers.


  latency and core audio
Posted by: nfraser52@gmail.com - 04-26-2020, 01:25 PM - Forum: Help with Mac Client Problems - Replies (10)

HI I have recently purchased a refurb macbook pro  13 ( 2015) Version.

With a Blue USB mic I get lousy Latency regardless of settings.

With Internal mic I get 5.9MS , but obviously the mix between vocal and instrument is kind random .

I am looking for a good medium price interface that works with mac OS Mojave.

I had ordered a Focusrite Solo Package ( as i also need a good Mic) , it is on back order and they offered M-audio air 192-4 as replacement .

Is anyone using the solo with a mac and if so what kinda latency are you experiencing ? , friends using solo with PC are experiencng zero !!!

I have not seen any good reviews of the M audio air 192  , any feedback ?

I believe that focusrite had a driver that can bypass the core audio , but I could be wrong

PLay Safe Y'all

  mic not working? check your firewall.
Posted by: Colin.Bryant - 04-26-2020, 11:17 AM - Forum: Help with Audio Gear - No Replies

Just solved one of our band members problems - his webcam mic could not be heard by others. Found that he had a McAffee firewall as part of his Internet security and that was blocking some 'messaging' packets from JK. 
Attempt to have a band session and then check the firewall log to see what packets have been blocked and consider 'allowing' them - can't be done on a solo session has to be communication to the network outside your gear.

  App doesn't open win 10
Posted by: ltroiani@gmail.com - 04-26-2020, 01:52 AM - Forum: Help with Windows Client Problems - Replies (22)

The app isn't coming up after I double click on it. I can see it appearing on Windows task manager momentarily, but it goes away after a few seconds.
I've installed the client a few days ago, and never saw it running. I've reinstalled it, reset all my internet settings, disabled the firewall, updated Java, rebooted many times. Nothing seems to fix the problem.
Anybody have the same issues? Any ideas that I haven't tried?

  Problem controlling mix - help appreciated!
Posted by: DrFunkySpoon - 04-26-2020, 12:24 AM - Forum: Help with Live Jamming Sessions - Replies (1)

Hi - My buddy and I tried out Jamkazam today. It worked and we loved it, but we had problems controlling the mix. The basic problem was that the mix sounded very different to him and to me, and we didn't know how to change this.
For him, my vocal was way too loud and my guitar was way too soft. I tried adjusting it with the sliders in my own session mix, and I can adjust my mix so that it sounds right to me: in my headphones my guitar and vocal are balanced, and his bass sounds right. But in his headphone my guitar is extremely soft so he can barely hear it, but my vocal is super loud.
It would be great if he could mix my two tracks separately in his phones, but he doesn't see my two tracks as separate. He only sees one track for me in the session, with one slider for my guitar and vocals mixed together, even though I have two tracks going, and I can see them both and move the sliders separately.
Can we control our mixes separately?  He needs to turn my guitar up and my vocal down in his phones, but we don't know how to do that. It seems that I control the balance between my two inputs, and the way he hears them is totally different from the way I have it mixed on my end.

Another strange thing is that he can only see one track for me, even though I have two separate tracks for guitar and vocal, and I can see only one track for him, even though he has two tracks: a bass track and a vocal track. 

Anyone who has figured out how to control the mix in this thing, please help. I really appreciate it!  Thank you.

  Which is better. USB interface or mixer?
Posted by: Bigfoot - 04-26-2020, 12:21 AM - Forum: Help with Audio Gear - Replies (2)

I'm a newbie to JamKazam and stuck in the analog world. I'm a drummer looking to jam with my band mates that moved away. I would like to know which is better a USB interface or a USB mixer. I currently using a Yamaha MG166CX analog mixer. Would it be better to connect that to a USB interface of get a USB mixer. I'm looking at Focusrite, M-Audio or Prosonus interfaces or a Mackie ProFX10V3. Any input or suggestions would be wonderful.


  Bias FX 2 causing I/O Jitter?
Posted by: lchomycz@comcast.net - 04-25-2020, 10:26 PM - Forum: Help with Audio Effects Plugins - No Replies


Hope you all are well!

Running a Presonus Studio 24c with  Bias FX 2 32bit plugin. I'm having I/O Jitter issues every so often, not all the time. Also seems to happen when changing effects, but that could be just coincidence. Comes and goes sometimes for a short period of time - minute or two, sometimes much longer. PC Processor is set to performance (100%) available for all processes. Usage in JK shows max 15% processor usage. Today I changed my setup to use my Avid Eleven Rack and Vocal mic out of a mixer into the Presonus 24c, now I have absolutely no issue. Just for the heck of it, I ordered a Behringer  UMC202HD, I gotta see if my theory is correct, also I'd rather use Bias FX 2 if I can. Sounds great when it works!

Anyone else experience this?


  App Crashes when I start a Solo Session
Posted by: Flotschi - 04-25-2020, 06:29 PM - Forum: Help with Mac Client Problems - Replies (1)

Hello everybody,

I tried to start a Quick Start Solo Session. The App does load for a moment and then the app crashes and closes completely.

I don`t know what's wrong. I hadn`t that problem before the last update. Is there a way to get the old Version then I could try that?

I´m using a Mac.
