Solid State Logic 82S6MC060A Guidelines for Plug-in Delay Compensation, Cubase SX + Nuendo 2/3

4.4 Guidelines for Plug-in Delay Compensation
When Duen de plug-ins are used, the aud			io data to be
processed by Duende is sent to the Duende DSP engine by the
host application. The audio is then processed by the DSPs and
sent back to the host application.
This transfer of au dio data	produces latency (delay) in the
audio signal being processed. Latency time is dependant on
the samp le rate, type of plug-in(s) l		oaded and the audi o
interface buffer setting.
If this latency is not com pensated, the processed audio will
arrive la te in relation to the unproces		sed audio. The more
processing that takes place on a particular signal, the later it
will arrive back in the host.
Most host ap plications automat ically com pensate for t his
latency by simply turning on the Plug-in Delay Compensation
(PDC) or s imilar, usually found in the appli				cations
preferences. Some hosts e	ven provide full pl			ug-in del ay
compensation thro ughout the enti re signal			path, incl uding
sends, groups, and buses.

The location of the settings for the PDC option within some common host applications is as follows:

Cubase SX + Nuendo 2/3:

Always on unless the ‘Constrain Delay Compensation’ feature is used to disable delay compensation on individual plug-ins: ‘Devices Menu>Plug-in Information>Use Delay Compensation’

Logic Pro:

‘Preferences>Audio>General’

Digital Performer 4/5:

‘Setup menu>Configure Audio System>Configure Stu dio Settings...’

Ableton Live:

‘Options>Delay Compensation’

Important: Delay compensation is fully automatic and requires no user intervention when Duende plug-ins are used in hosts that support full Plug-in Delay Compensation.
