Before the first jam
Right now Late Set rooms run on Jamulus, a free, well-tested program for playing music together over the internet. Ten minutes of setup, once. A one-click Late Set app that does all of this for you is coming.
Get the latest release for your computer from jamulus.io. Mac: open the .dmg and drag Jamulus to Applications (macOS may ask you to allow it under System Settings → Privacy & Security). Windows: run the installer.
Windows only: Jamulus needs an ASIO audio driver. If your interface came with one, install it. If not, install ASIO4ALL first.
Plug headphones into your audio interface (or your computer if you sing or play electric straight in).
Speakers feed the room back into your mic and everyone hears an echo. Bluetooth adds too much delay.
Connect your instrument or mic to your interface, then the interface to the computer. In Jamulus, open Settings and pick that interface as both input and output.
Set the buffer size as small as it goes without crackling. Smaller buffer, less delay.
If you can, run a network cable from your router to your computer for the jam.
Wi-Fi adds jitter that sounds like stutter. A cable is the single biggest upgrade for most people.
In Jamulus, open My Profile (Settings → My Profile on Mac, the Profile button on Windows) and type your Late Set handle with the @, for example @maya.
Otherwise you show up as “No Name” and the band can't tell who's who. The name is saved, so this is a one-time step.
Open the room page on Late Set a few minutes before start. Once you have a slot, a Relay address appears with a copy button. In Jamulus, click Connect, paste the address into the server field, and connect.
Mark yourself Ready on the room page when you can hear yourself.
