Aj-snapshot

Aj-snapshot is a small program that can be used to make snapshots of the connections made between JACK and/or ALSA clients.
Because JACK can provide both audio and MIDI support to programs, aj-snapshot can store both types of connections for JACK.
ALSA, on the other hand, only provides routing facilities for MIDI clients.
You can also run aj-snapshot in daemon mode if you want to have your connections continually restored.
