**Direct questions about registration to Laurie Siegel: earthgull@hotmail.com

In our first workshop in January, the developers of these three platforms introduced participants to the basic concept of minimizing latency when making music together online, as well as to the unique strengths of their respective platforms.  Each of these three platforms enable singing together without the delay (latency), which makes synchronous singing close to impossible on Zoom and other common video conference platforms.  PMN members are invited to participate in as many of these practice sessions as they wish in order to get a broad view of the available options.

Requirements for Participation:

A. Download the Jacktrip software.   Instructions:

Download the Software here:  https://jacktrip.zendesk.com/hc/en-us/articles/360053152854-JackTrip-Downloads

Note:  On a Mac, you may have to right click on the installation .pkg file in your downloads folder and choose Open, if you get a message that it's from an unverified developer.

Download and install the following packages: 

For Mac OSX users:

The Jack Server – You will have to restart after installation, as per instructions. 
As well as running the package installer, make sure you copy QJackCtl.app into your Applications folder.

For Windows users:

Download and install the following packages:

The ASIO4ALL driver – This makes it easier to use Jack on Windows.
The Jack Server

Windows users:   in order to experience the low latency of any of these programs, you will need to install an ASIO driver. If you are using your built-in mic and speakers, you can use ASIO4ALL.  

Again, you will have much greater success if you can use an audio interface with a microphone and headphones.  In this case, you need to Google "ASIO driver" for your device. This should give you the manufacturers downloads page where you can find, download and install an ASIO driver for your device.

B. You must be a PMN member in good standing. (If you are not a PMN member, you may join here: https://www.peoplesmusic.org/join-PMN)

C. If you did not attend the first workshop, please watch the full video before the practice session.

D. Technical Requirements during the session:

  1. Use headphones or earbuds.  Please do not use a speaker; it will cause feedback.
  2. Using a microphone plugged in to an external audio interface works best.
  3. To minimize latency, please connect your computer to the internet via ethernet connection (not Wifi). 

*** Upon completion of the form available at the "Register" button on the left, you will receive an immediate email confirmation.  You will receive the actual Zoom Meeting link for this workshop from Laurie Siegel <earthgull@hotmail.com> at least one day before the practice session begins.
