Duende User Guide

Any tracks that have a smaller latency than the maximum must also be delayed but by a smaller
amount (i.e. tracks with 1 Duende plug-in where the maximum has 3). The delay value for these
will be maximum latency minus the latency reported by that track.
Using Automatic Delay Compensation in Pro Tools HD
Pro Tools HD users have the luxury of being able to use Automatic Delay Compensation, as
opposed to the manual method required in Pro Tools LE and M-Powered. However, there are still
some considerations to be taken into account to make sure all Duende plug-ins are compensated
for and everything stays perfectly in sync.
To turn on ADC in PTHD go to ‘Setup>Playback Engine’ whilst Pro Tools is stopped and you will
see a box labeled ‘Delay Compensation Engine’. Change the setting here to ‘Long (4095 Samples
per channel)’.
Pro Tools will then tell you that it will close and re-open your session after clicking the OK button
in the dialogue box; therefore make sure you have saved your session prior to doing this. Also put
the CPU usage limit to 85%.
Pro Tools will now automatically compensate for any introduced latency of 4095 samples or less.
