Does component visibility get set to 0 on plugin GUI close?

[Christoph Hart]

@aaronventure no, the suspension callback happens for each instance of your plugin.

There is just the possibility that one plugin instance creates more than 1 interface (all plugin standards allow this and there are some hosts which allow having more than 1 interface open, even if it's just for a short amount of time).

So every instance tracks the amount of open interfaces and suspend their timers by calling this callback with true whenever the count reaches zero.

• never ever use the timer object for anything related to MIDI processing. The frequency is as jittery as it can be so unless you want to create a random glitch machine, you absolutely need to resort to the onTimer callback.

Well this confuses me, I think it says: dont use a timer object , instead use a timer object...unless you mean something different by "resort to the 'onTimer' callback"

Perhaps this is saying: dont use a Panel.timer, or an Engine.timer, instead use a Synth.timer.

Yes. Only the synth timer is sample accurate.

yup, with onTimer I mean the callback called onTimer :)

..and I get 4 of these per Sound Generator - so this thread is confusing me more and more...

I have an arp, its in a ScriptProcessor - in the MAIN container... not in a sound generator...what timer should I be using?

For anything that's related to the audio or MIDI output of your plugin, use the synth timer.

For the GUI, use the panel timer or a timer object.

yeah thats not answering the question tho is it. I've held on to the above rule-of-thumb for the 5 years I've been building HISE instruments. But now I learn that Synth.timers are attached to sound generators and as far as my mental model works a Script Processor is not a sound generator.

Very happy to be proved wrong.

@Lindon The master container is still a container and a container is a type of Sound Generator, according to the docs

I think that's what this remark was about

It's 4 timers per Sound Generator, not per container

[Lindon]

@aaronventure thanks OK missed that in the docs, mea culpa, so I can go back to my mental model without any nausea inducing changes at my age....

[Christoph Hart]

Yup a container is a sound generator.
