Returns the set of potential Pro DJ Link synchronization sources which are currently visible on the network, summarized as maps containing the device name, player number, and IP address.

Return a set of only those sources whose name matches the specified pattern. name-filter can either be a Pattern, or a string which will be turned into a pattern which matches in a case-insensitive way anywhere in the name.

Makes sure the supplied DJ Link source is current and valid. Returns it, or throws an exception.

Looks up a source with a name that matches the specified pattern. name-filter can either be a Pattern, or a string which will be turned into a pattern which matches in a case-insensitive way anywhere in the name. Returns the single matching source found, or throws an exception.

Shut down the beat-link library.

Activate all the components of the beat-link library. Runs in the background, since it can take a while to give up if there are no DJ Link devices on the network.

Returns a sync function that will cause the beats-per-minute setting of the supplied metronome to track the values received from the specified DJ Link transmitter on the local network. The sync source can be specified either as a map that would be returned from current-dj-link-sources, or a regex Pattern, or a simple string, which will be converted into a case-insensitve pattern matching anywhere in the source name. This method is intended for use with show/sync-to-external-clock.

If sync-bars? is passed with a true value, then synchronization will honor the beat-within-bar information coming from the DJ Link device. Otherwise, sync will be at the beat level only.
