  • Ogg Vorbis Encoding quality:

  • LOW (Standalone/json) sets quality to -0.1; upload bandwidth needed: ~48 – ~64 Kbit/s.

  • NORMAL (Standalone/json) sets quality to 0; upload bandwidth needed: ~64 – ~80 Kbit/s.

  • Quality set to 0.1 (editing json file only); upload bandwidth needed: ~80 – ~96 Kbit/s.

  • Quality set to 0.2 (editing json file only); upload bandwidth needed: ~96 – ~112 Kbit/s.

  • HIGH (Standalone/json) sets quality to 0.3; upload bandwidth needed: ~112 – ~128 Kbit/s.

It is possible to set any value between -0.1 and 0.3 directly in the Jamtaba.json or Jamtaba64.json file editing the encodingQuality value (use this method to change the VST/AU Plugin quality):

.

This values apply to each channel, so if you use two channels in Jamtaba, your bandwidth requirements will double. Overall our tests have shown that NORMAL is an adequate encoding quality for most instruments, but feel free to experiment with the HIGH setting if you feel you need an extra quality sound.

Just open the corresponding Jamtaba.json or Jamtaba64.json file in a text editor and save. This files are located under [user]/AppData/Roaming/JamTaba 2.

NOTES:

  1. The VST/AU plugin has a separate folder where there is another Jamtaba.json and Jamtaba64.json file that has independent settings, so be careful which one you're editing (standalone or VST/AU Plugin).
  2. For versions 2.0.18 or earlier, the files are located in [user]/AppData/Local/Jamtaba 2.
  • CPU Optimization:

If you are running low on CPU resources (specially in old computers and monocore CPU systems) you can change the refresh cycle time for all GUI proceses (i.e. peak meters, wave display).

To do this, open the corresponding Jamtaba.json or Jamtaba64.json file located under [user]/AppData/Roaming/JamTaba 2 and change the refreshRate value to any number greater than 0. The default setting is 30 (Hz), so a lower value here will require less CPU power for GUI drawing. The maximum refresh Rate value allowed is 60.

.

NOTES:

  1. Please close Jamtaba before changing this option for correct saving of the new option.
  2. Standalone and VST/AU versions have different .json files so each setting is independent from each other.
  3. For version 2.0.18, the files are located in [user]/AppData/Local/Jamtaba 2.
  • Editing Presets Names:

In order to change a preset's name you need to locate the Presets or Presets_x64 folder located under [user]/AppData/Roaming/JamTaba 2 using a file manager application and edit or delete the .json file name corresponding to the preset you need to modify.

NOTES:

  1. The VST/AU plugin has a separate folder where there are additional .json Preset files that are independent from each other, so be careful which one you're editing (standalone or VST/AU Plugin).
  2. Presets for the Standalone x86 and x64 versions are incompatible with each other.
  3. For versions 2.0.18 or earlier, the files are located in [user]/AppData/Local/Jamtaba 2.
  • Editing the private servers list in combobox:

If you need to edit the url or remove any server name from the list that appear in the private server combobox, you'll have to do it manually. This entry can be found in the corresponding Jamtaba.json or Jamtaba64.json file under [user]/AppData/Roaming/JamTaba 2:

.

Remember that new servers are added automatically when typing new ones and connecting. No need to edit in this case.

NOTES:

  1. The VST/AU plugin has a separate folder where there is another Jamtaba.json and Jamtaba64.json file that has independent settings, so be careful which one you're editing (standalone or VST/AU Plugin).
  2. For versions 2.0.18 or earlier, the files are located in [user]/AppData/Local/Jamtaba 2.
  • Reaper Voice Chat and Session Mode:

This are special modes Reaper uses for different purposes. Jamtaba can recognize users using these modes, but they will work the same as normal users.

Voice Chat: This mode is used when you need the server to send the audio to the clients immediately after it's received. This will make it impossible for the user to jam normally because the latency will not be adjusted according to BPI. Others will hear the audio out of sync. The purpose of this mode is for telephone-like conversations over ninjam.

Session Mode: This mode is designed for online collaborations using reaper. Users using Session Mode will be able to Jam with Jamtaba users, but Jamtaba will override session mode and they will be heard in the same way as if the were in normal mode.

  • RMS Meter:

RMS (root mean square) is a type of measurement for a waveform equivalent to it's direct current that would produce the same power dissipation. It is used as an alternative to peak meters because it shows a more "natural" visual feedback.

  • Jamtaba VST (Windows) and AU (MAC) Plugin Supported Hosts:

Currently Jamtaba VST/AU has been fully tested to work in latest versions of Cubase, Live, Reaper, Studio One, Sonar, Logic and Energy XT . Some earlier versions of these hosts are not supported, so please use the latest one available.

  • Unsupported VSTPlugins in Jamtaba Windows Standalone:

Our tests have shown the following VST plugins are not working in Jamtaba Standalone at the moment:

Kontakt 4, SampleTank 2, Eastwest - Quantum Leap Symphonic Orchestra, boost11, sonitus plugins.

For more information and reporting, please use this thread: https://github.com/elieserdejesus/JamTaba/issues/91

  • Screen Saver Blocker (Mac & Windows only):

In Windows while connected to a Server, Jamtaba will automatically avoid interruptions caused by the screen saver (if any). Normal operation will resume when leaving the room.

In Mac computers the Screen saver will be disabled when Jamtaba is started. Normal operation will resume when closing Jamtaba.

  • Customizing the VST/AU plugin window size (Mac & Windows only):

If you need a custom size for the plugin window, you'll need to edit the corresponding Jamtaba.json or Jamtaba64.json file in a text editor and change the Height and/or Width values manually.

.

These files are located under [user]/AppData/Roaming/JamTaba 2/VstPlugin. You can choose any value for Height from 600 up to 900 and for Width from 990 up to 1485. Save the .json file and relaunch your host.

NOTES:

  1. Please close the host before changing these values. Every time you close Jamtaba standalone or the host D.A.W., these values are saved with the last ones used.
  2. Maximum Height and Width values may not apply to your specific screen size.
