DXi's & Look-ahead Processing at high Latencies

Last updated on 3/18/2016

The information in this article applies to:

  • SONAR 3 - 6
  • SONAR Home Studio 4 - 6
  • Music Creator 3 - 4

Some plug-ins, such as the Sonitus:fx Multiband and other dynamics processors, use a look-ahead buffer mechanism, which results in a short delay being introduced to the output signal when the plug-in is used in real-time. SONAR's automatic delay compensation (ADC) takes care of any delays, but you may experience some anomalies when using such a plug-in to process the output of a DXI-especially if SONAR is configured to use a high mixing latency. The symptoms include audio that appears to drop out, and/or missed notes (from the MIDI track that is assigned to the DXi). Again, this is more prone to occur with higher latency settings.

This may happen if SONAR doesn't pump ahead enough MIDI data to compensate for ADC.

To fix this problem, go to Options > Global > MIDI and Increase the Prepare Using [n] Milliseconds Buffers Value.
