Hi,

Idle and idle are two completely different things.
Idle tasks or processes mean the CPU cycles not normally used by the system or user.
Idle timer in events API (InstallEventLoopIdleTimer) is the timer getting active, when user does not send events from GUI (such as mouse clicks).
In fact, using standard timers (InstallEventLoopTimer) is very similar to "fill" the processor's idle time, they have very low priority in most OSs.

But there is a difference between InstallEventLoopIdleTimer and InstallEventLoopTimer, isn't it ? I had read (but maybe am I mistaken) that Loop Idle trigger an event synchronous to the GUI thread when that system is idle.

fyi, I tried this, but it doesn't seem to work. I simply replaced
InstallEventLoopTimer in VST2AU with InstallEventLoopIdleTimer.
But, when I did so, the timer callback is never delivered.
Perhaps Logic always keeps something in the event queue, thus
preventing the timer callback from being triggered? Oh well, it
was worth a try. So, now I'm back to where I started :-). It
appears this really should be handled by the host.
