Do these methods run on the same thread as the processBlock? Should they suspendProcessing if they're time consuming? ---

They could be run on any thread, so yes, you may want to suspend the processing while they run, depending on what your implementation needs to do. ---

Following up on this older thread… In the case of an AAX plug-in, I see setStateInformation being called from the AAXH\_HighPriorityAAXHMixerRampeUpdateThread. In the JuceDemoPlugin (Juce 3.0.1), I see that gain and delay (of type float) are being set here. Both gain and delay are read from the JuceDemoPluginAudioProcessorEditor::timerCallback which will be called on the main thread. Wouldn’t there be a race condition since float is not an atomic type? How do other plug-in developers deal with thread safety issues of data being set in setStateInformation and read in other threads?
