  Using computer mic & speaker
Posted by: cgossett72 - 03-16-2021, 10:55 PM - Forum: Help with Audio Gear - Replies (1)

I'm new to JK, hoping to jam with a distant friend.  I've read instructions that indicate I should be able to operate using my computer's mic and speaker (although I'm using headphones), but when I try to create a private session, I get popups indicating either a mismatch between input and output sample rates or simply "unable to open output device".  In this condition, I'm unable to create a session.  Any suggestions out there?  Do I need an audio interface to get past this?  Thanks in advance for any help!

  Best - Tina Turner
Posted by: Voicegarden - 03-16-2021, 04:16 AM - Forum: Help with JamTracks - No Replies

i just purchased Tina Turner's 'Best' JamTrack and there is a missing file in the individual track downloads.
It's the percussive bass sound (piano?) which is a signature part of the song especially in the intro.
How can I get hold of this individual file? 
Any help would be greatly appreciated.

  Help with finding open Jams to join
Posted by: mportman - 03-15-2021, 05:53 PM - Forum: Help with Live Jamming Sessions - Replies (1)

Hello Jammers,

I'm a noob JK'er who has no other friends on JK. Being a techno-nerd I was immediately interested in using JK as a way to connect with my former bandmates since we now live far apart. My problem is that no one else I know has the tech chops to get JK up and running so here I am by my lonesome and I'm not the type who would normally stroll into a jam session with other players I don't know.

I'm a rhythm guitar player and vocalist...mostly dead tunes & covers. My wife plays keyboards/percussion/vocals and is more shy about jamming with strangers then I am.

I've skimmed the forums and see tons of good help for the technical side of JK setup but I haven't yet found any guidance on finding and joining jam sessions with people I don't know. Have I missed some online instructions somewhere?  Can anyone walk me through it? What is the best way to search for and join live sessions with people I don't know...and what is the etiquette for these type of sessions?

  Find which session friend is in.

Hi, just wondering if anybody knows if there is an easy way to find which session a friend is in currently without sending him/her a message.  This is assuming that you know they are logged into JK and not wanting to go scrolling through all the current sessions.  Thanks.

  Different Internet Latency
Posted by: c-sasse - 03-12-2021, 09:03 AM - Forum: Help with Network Gear - Replies (2)


I'm new to Jamkazam and experience latency problems due to internet connection when jamming with my band (6 players). The iinternet latency is high, with values above 50ms, ranging up to around 200 ms. My personal audio interface's latency is around 5 ms and input/output jitter is floating around 0 ms. My internet connection is rather slow, with around 3 MBps download and 1.5 MBps upload. I am using a LAN connection to my router.

However, if I am jamming with one friend of mine who has a high-speed fibre connection, my own slow connection does not seem to produce latencies. The audio stream is fine and we can play in sync.

Is it just the fibre connection which causes the different behaviour or am I missing something?

Best regards

  Problem getting jamkazam to connect with Steinberg UR22C audio interface
Posted by: memerunner - 03-12-2021, 01:58 AM - Forum: Help with Audio Gear - Replies (2)

I have a 2017 MacBook, and purchased the Steinberg UR22C because of it working with the USB-C port on my MacBook, and it's low latency rating.

In My Account > Audio Profiles, jamkazam isn't connecting with my Steinberg UR22C. It doesn't show the device as 'active'. When I click to activate it, it says it isn't connected to it. 

I have screen shots below.

Is there some way to check the UR22C on my macbook to troubleshoot whether the problem is between the ur22c and my macbook, or the macbook and jamkazam?

I did have it connected at one point, but haven't been able to connect it again. 

I've also had audio issues (my mic isn't working - my speech is a horrible static buzz), so maybe there's something wrong with my audio output settings? More screen shots below.

Greatly appreciate any help on this. Been trying a week and wondering if there's something fundamentally wrong with my setup.

  Scarlett Solo no sound
Posted by: JGibson74 - 03-11-2021, 06:38 PM - Forum: Help with Audio Gear - Replies (5)


I'm getting really crazy trying to setup Jamkazam with my Scarlett Solo 2ng gen.

I have setup the audio gear with ASIO USB, input1-2 and output 1-2.
In that ASIO I have sample rate 96khz and buffer at 16. (I have a pc i9, 32Gb ram, really high mix/mastering with cubase and lots of vst; never had issues).
I finish the setup, play the test audio very well and launch a test session.

And TADA ! no sound at all. The sound levels on the the soft doesnt go up, like there was no sound from the audio gear...

Direct monitor is never on.
I plug my headset or speakers always in the front jack output.
Sound with system is working as I always use the Scarlett like this.

If I open guitar rig for exemple, I hear my guitar, Cubase is working fine.
But when I try Jamkazam, no sound. My colleague dont hear me also...

I tryed uninstall/reinstall driver, jamkazam, etc...

It's not working at all....

If someone could help me...

Question "enough bandwidth to send you a degraded, but sufficient, audio stream."
Posted by: ellis@hillinger.org - 03-11-2021, 03:20 PM - Forum: Help with Network Gear - Replies (8)

I'm trying to understand the diagnostics JamKazam provides so that I can equate them to the bandwidth available for our sessions.  The typical case is two players with wind instruments.  One player has 25 Mbps download and 14 Mbps upload, while the other has 90 Mbps download and 18 Mbps upload speeds.  This is far more than the 1 Mbps minimum that JamKazam published: https://forum.jamkazam.com/showthread.php?tid=114.  (Really?)  We have not analyzed the traffic from other users on these connections, but since our results have been consistent during different sessions, this doesn't appear to be the determining factor.  We are both using current Windows 10 systems and Focusrite Scarlett USB adapters.

My question is about bandwidth, not latency, but I should note that we are having challenges with delay.  We are about 100 miles apart, and one of the players is on an island.  The challenges of providing service at that remote location seems to push the total latency above 50 ms.

Our results with this configuration are generally stable, although there are some artifacts (especially on high notes) that are of concern.  When we examine the "Audio Bw Rx" status it usually says <other player> "has enough bandwidth to send you a degraded, but sufficient, audio stream."  While I haven't found documentation about this specific message, the documentation (https://jamkazam.freshdesk.com/support/s...iagnostics) says this shows the size of the audio stream and that these will be automatically adjusted.

What exact parameters is JK looking for, and what does it means by "enough bandwidth" in this situation?

Music Mixing a live band (Zoom instructions as well)
Posted by: UPC04539 - 03-11-2021, 01:23 AM - Forum: Help with Audio Effects Plugins - No Replies

I thought I would share my PC setup as I had to dig here and there to make it happen.  My goal was to be able to mix a full band in a live setting (without me playing).  I have issues using the Jamkazam audio mixer for various reasons :

  • The app is a bit slow on my PC (don't know why)
  • The sliders are not very smooth
  • VST usage is limited and not super easy to setup
  • Native controls like compressors are not easy to use
So, here is what I do.  I connect my interface to a 32bit DAW (Reaper in my case).  From there I use Rearoute to send my sound in Jamkazam (32bit).  Please refer to the following post for more details :

REAPER + Jam Kazam via ReaRoute [TUTORIAL] - Cockos Incorporated Forums

Then, I am muting the track with ReaRoute that comes back from Jamkazam in Reaper.  This brings back a full mix and is of no use for mixing.  

NOTE - The "sound technician" needs to be in the Jamkazam session but won't play.  You will get a bit of latency coming back  from Jamkazam to Reaper unfortunately using Reastream.  If you just bring a full mix back with Rearoute, you will be able to play with the band and send your audio to OBS (see next steps).  But you won't be able to mix individual tracks.

Next, I use Reastream (32bit) to connect each musicians tracks to Reaper.  Once this is complete, I send the master mix out of Reaper to OBS via Reastream.  Please follow this guide for more details :

Live Stream your DAW through OBS! How-to guide - YouTube

To get each musician's track in Reaper, I go in the Jamkazam's mixer and add the VST Reastream using the method explained in the video above.  Create one track per musician in Reaper and link them to Jamkazam with Reastream.

Check this post for help on Jamkazam and VST's :


Add FX required on each track in your DAW depending on what is coming through (guitar, vocals, bass, keys, etc.)

Once this is completed, I use a virtual cable to get out of OBS and send the audio to Zoom.  To do so, install the virtual cable B.  Then in OBS you need to set the monitoring device to Virtual Cable B in Settings - Audio - Advanced

VB-Audio Virtual Apps (vb-audio.com)

NOTE - You could also stream it directly from OBS on other platforms.  For Zoom, you need a transition setup between Reaper and Zoom and the best performance I got was this way.  I tried Voicemeeter and other solutions but I could not get any good sound out of it.

Zoom allows you got receive and send a Stereo signal to the audience.  Please refer to this link for more information on setting up the Stereo sound in Zoom :

Zoom Software in Music Mode - Best Audio Settings | Music Repo

NOTE - Zoom does frequent upgrades so these options may changes in future version but at least you know what to look for at this point. Also, to really have the proof of Stereo, have a buddy join your Zoom session to test it out and confirm or join your own Zoom session on a second device and listen. Recording Zoom sessions will be converted to MONO... for now... and if you try "Test the mic" you won't hear the stereo as well. Only Zoom attendants will hear the Stereo.

And boom voilà!  You get a full band audio in Stereo in Zoom.  Use the PAN in the DAW on tracks and FX and have fun!

Note - In the Jamkazam mixer I find that the pre/post amp helps if it's turned on.  You may use some Make-up gain if a musician's level is very low.  But ideally each musician should make sure to send a strong and clear signal to Jamkazam for you to use in your mix.  They should ideally send a signal with no reverb so that you can control it on your end.  Each musician must make sure their setup is balanced.  Ex : clean guitar VS distortion VS singing with an instrument.  Musicians can add input tracks in their Jamkazam, but you will only get one track on their output!  So if a singer plays guitar, they need to balanced their sound as good as possible to make your job easier.  I would love to get multiple inputs from musicians using more than one thing on their end.
