link_tempo_set — Sets the tempo.


Plugin opcode in ableton_link_opcodes.

Sets the local tempo if this peer is not enabled; sets the tempo of the global network Ableton Link session if this peer is enabled.


link_tempo_set i_peer, k_bpm [, k_at_time_seconds]


i_peer -- The Ableton Link peer object.

k_bpm -- The requested tempo in beats per minute.

k_at_time_seconds -- The session time at which the indicated tempo will take effect. The default value is the current session time.


Here is an example of the link_tempo_set opcode. It uses the file ableton_link.csd.

Example 482. Example of the link_tempo_set opcode.

Run the Ableton Link "LinkHut" example application, or some other 
Ableton Link peer, while you run this CSD to see what happens.
