Burst Train Lag

Macro: TrainLag

This is the delay before the first full burst cycle (Lag, Rise, High, Fall, and Cycle) of a Burst Train begins. It is only given once when the output is turned on, or when a change to a control causes the output to be restarted. It allows overall alignment of burst trains on different Streams or output channels.

For example, suppose you want to create alternating Left and Right bursts, with the Rise of one channel exactly overlapping the Fall of the other so that if the two channels are combined they will produce a steady continuous tone. To do this, you would set all Rise and Fall values equal, and set both High values to the desired burst duration. In order that the silent portions exactly match the High portions, set Burst Cycle values to Rise plus Fall plus two times the High value.

Now you have two identical burst trains, exactly overlapping. If you set Train Lag on one of them to the sum of Rise plus High, that channel will start its initial Rise just as the other is starting its initial Fall, and they will keep that time alignment on subsequent bursts.

Macro Notes:

L.1.TrainLag=100 sets Left Stream 1 Train Lag to 100 samples, assuming Smpl mode. It will set 100 seconds in sec mode. To be safe, use a SmplSec command to set the desired mode before using this command.

L.1.TrainLag=>1 increments and L.1.TrainLag=>-1 decrements by one sample, even in sec mode. Only +/-1 sample steps are allowed.
