Plug-in Load Balancing enhancements

Plug-in Load Balancing now uses significantly less load when running at low latency.

 

Note: Plug-in load balancing will not lower CPU use as compared to load balancing being disabled, especially when running at lower latency. This is because load balancing uses smaller buffers than the audio engine buffer size.

Configurable Thread Count and Buffer size

Both the plug-in load balancing threads and buffer size are now configurable settings in Edit > Preferences > Audio - Configuration File.

When PluginLoadBalancingThreadCount is set to 0, the number of threads is adaptively managed and is less than the number of processor threads. You may change the value to utilize fewer or more threads.

MinPluginLoadBalancingBufferSamples defaults to 96 samples and is the size of the internal load balancing buffers. Setting the buffer size higher will use less CPU but may result in less load balancing. Please note that when the engine latency is less than twice MinPluginLoadBalancingBufferSamples, load balancing will be automatically disabled internally.

Plug-in Load Balancing active indicator

When Plug-In Load Balancing is enabled in Edit > Preferences > Audio - Playback and Recording and load balancing is active, the FX Rack header tooltip shows (PLB) next to the audio processing load.
