How do I change patches?

Most people will be able to use the default patch set (2-channel stereo, using USB interface channels 1 & 2 for capture and playback). In some cases, such as a USB interface where you want to use channels 3 and 4, you might need to create and use a different patch set.

The patch settings are loaded by the app start script as set in its config file, and can be changed by first creating a new patch file, then changing the config setting to use the new patch file.

Make a Working Patch
First you'll need to find a patch set that works:

• launch Jamulus (or SonoBus, they have separate patch files) using the desktop icon..
• launch Patchage using the desktop icon. (QJackCtl is available from the menu, but Patchage is recommended).
• change patches until you find the setting you want.

Save the Patch with aj-snapshot
Open a terminal window, then use aj-snapshot to save the current patch set in directory "~/.config/aj-snapshot/

aj-snapshot ~/.config/aj-snapshot/snapshot-name.xml

Change config file to use the new patch
Only the filename is needed, default directory is ~/.config/aj-snapshot/

# Jamulus:  edit file ~/.config/Jamulus/jamulus_start.conf
AJ_SNAPSHOT=<snapshot-name.xml>

# SonoBus:  edit file ~/.config/sonobus_start.conf
AJ_SNAPSHOT=<snapshot-name.xml>
