Detailed setup for Mac users

Online jam sessions in the nation's capital

  1. Download the latest Mac version.
    1. Open the downloaded .zip file and the Jamulus.dmg file inside it.
    2. Copy the Jamulus app to your Applications folder.
  2. Open Jamulus from your Applications folder.
  3. Click the “Settings” link to configure your audio.
    1. Before anything else, set your audio quality to HIGH. It won’t add any more lag on a recent computer and a good internet connection.
    2. The “Device” selection under “Soundcard” will let you tell Jamulus how to get sound in and out of the app. Inputs are listed on the left side and outputs on the right.
    3. In the most basic setup, you will use a pair of headphones to listen, and your computer’s built-in microphone to play into, so select the first option (System Defaults). Jamulus will use whichever devices you have selected in your Mac’s “Sound” settings.
    4. In a basic setup, start with “Mono” setting for Audio Channels.
    5. Open your Mac’s System Preferences and click “Sound”, then the “Input” tab. Check that your mic is selected, and set your input volume so it’s right about in the middle when you sing or play your instrument.
    6. Also check your system’s “Output” settings so your headphones are selected.
  4. Back in Jamulus, close the Settings window and set up your profile (“My Profile”).
  5. Finally, click the “Connect” button.
    1. You will see a list of public servers all over the world. Ignore these, and enter the District Jam primary server, “”.
    2. The meters on the left should light up green when you sing or play. Check this first.
    3. You should also see a volume fader for each participant in the jam. This is your personal monitor mix; adjust them up or down to suit your own preference. Your mutes/solos and levels will not affect anyone else’s mix.
    4. Try starting with YOUR OWN volume fader all the way down. While one of the goals of Jamulus is the lowest possible latency, you are probably more sensitive to latency in your own performance than you are to the others in your jam. With your own fader up, you will hear yourself in the headphones WITH this small amount of delay, which can be distracting or difficult. We ultimately recommend using an audio interface (see advanced audio setup) with low-latency headphone monitoring.
