The file adb_bpmmaster.xml has the macros already written for all 4 BPM masters (Titan v10). Here, we use BPM master 1 to explain it.

The Titan IDs have slightly changed from v10 to v11 see titanId, and while the mentioned reserved IDs are a good starting point, there is no guarantee they haven't changed in your show. If these macros do not work for you then try to find the Titan IDs of your masters and adjust the macros accordingly.

This explains the functional steps within the sequence. For all the other XML details please refer to Formats and syntax

• Masters.DoubleOrHalfSpeedMultiplier(1607,false) halves the bpm speed of bpm master 1 which is identified by its fixed titan ID
• Masters.DoubleOrHalfSpeedMultiplier(1607,true) doubles the bpm speed of bpm master 1 which is identified by its fixed titan ID
• Masters.TapTempo(1607, Math.GetCurrentTimeStamp()) taps the bpm speed of bpm master 1 which is identified by its fixed titan ID. The timestamp is a required parameter for this function to work, see Masters.TapTempo
• Masters.ResetSpeedMultiplier(1607) resets the bpm speed of bpm master 1 which is identified by its fixed titan ID

1. make this macro available
2. apply when needed (you'll see the results when you have BPM masters assigned)
