Script Processor onTimer() Callback

[Phelan Kane]

Hiya All

I am having a few problems triggering the onTimer() callback in a Script Processor. I want to use it to generate a counter running at 16th notes at the host's BPM, feed from the setOnGridChange callback.

I am using a button in the main scripts Interface to trigger the onTimer() within the script processor's onInit().

Everything works fine in HISE but it doesn't seem to work on compiled VST3's and AUs.

Enable Sound Generators FX is active in the project settings.

HISE 3.6.2. Mac OS 10.13.6. Yeah I'm old skool...

Any advice? Thanks in advance.

@Phelan-Kane no idea why it wouldn't run in vst.

Can you try and make a global variable for storing the steps and write to that, declare your label normally into a const, and use a UI timer to refresh the label instead? If you use a panel and a paint routine for the label, the panel comes with a built in timer that stops automatically when the UI is closed. if you want to use the label component and use a custom timer from the Timer class, you'll have to add a broadcaster that stops and starts it on UI close/open if you don't want it to run pointlessly in the back.

When you run the timer, simply have it sendRepaintMessage() to the panel. If you start it at 1000/30, that's 30fps. (it's in ms instead of seconds).

in your panel paint routine, simply draw the text and refer to the global variable for the value.

Right now, your realtime timer is updating component properties even when the UI is closed, which is unnecessary. You're also doing some string operations in there. Try to keep these out of the audio thread.

@aaronventure thank you.

Some good advice there. After some tests the timers run successfully in a compiled plug if the script processor timer is triggered on by a note on. I guess the noteOn() callbacks work more systematically than the onInit() callback.

You post was much appreciated.
