DELAY COMPENSATION511
Delay Compensation to Send FX busses
Since each mixer channel is delay-compensated individually, we need to make sure that any signals from the mixer
channels to the Send FX busses reaches the Send FX busses at the same time. To make the signals to each of the
Send FX busses come “in sync”, there is also a built-in delay compensation to the eight FX sends of each mixer
channel.
About Send FX Returns
Reason doesn't compensate for any inherent delays in the Send Effect devices themselves, as this would make the
delay compensation scheme extremely complex. Also, Send FX are traditionally often used for delays and reverbs,
where a little extra inherent delay won't matter much.
! In the situation where you might route the outputs of Send Effects back to separate Mix Channels, no delay
compensation is being performed on the “return” Mix Channels.
About the Master Insert FX
Reason considers all audio signals to pass through the Master Section in the main mixer; this is where all signals
eventually should end up in sync. But the Master Section has an Insert FX section too, and effect devices used here
can often have a significant inherent latency (maximizers, mastering EQs etc). However, since all signals pass
through these effect devices in sync, no delay compensation is performed on the Master Insert FX devices. This is
why the Master Section device in the rack lacks Channel Delay and Adjustment displays.
