Can I manually trigger a Callback function?

[Lindon]

@Morphoice correct - you probably want to do something on "empty" - like load an empty sample map, but for this I just jumped out of the callback so the sampler would keep its currently loaded sample

what problems are these?

It's been a while since I used it, the only I remember is if you want the option to have no buttons pressed then the radio group won't work. I thought there was some issue with restoring their state from presets too but I might be misremembering.

Since I'm usually writing callbacks for them anyway though it's not really any extra work to add a couple more lines to get radio group behaviour.

@Lindon @d-healey gotcha! seems to work like a charm, and it suddenly is successfully wirtten and recalled to/from a preset. that might - if I'm not overlooking anything - solve all my problems at once.

only thing I'd love to have is actually hearing the selected sample on selection but if I use the sample loading callback it would trigger upon preset restore aswell

Correct about the no-buttons-pressed option, never had an issue with them restoring state in 8 years of using them....slightly frightened now...

Your call....

It's more likely me misremembering some issue I ran into years ago.

they'll all be occupado in the end, I just wanted to focus on the functionality before I create all the sample maps and proceed to sample all my hardware drum machines

I dont really understand what you are saying in this last bit - you select a button and it loads that map - isnt that what you want?

yes. I was just thinking an audible preview of the sample after it's loaded might add some comfort for the user if they switch through the available samples

[Morphoice]

@Lindon I tried firing a note after the sample is loaded successfully but the problem was this would not work when the button is clicked but fire on recalling a preset, and there we wouldn't need it,

[Lindon]

@Morphoice so use the preset manager to set a "loading a preset" flag , and uncheck once the preset is loaded...

In your buttons check to see if this flag is set - if not then it really is a user pressing the button(not a preset loading) - so you can play a demo note...

https://docs.hise.dev/scripting/scripting-api/userpresethandler/index.html

you want setPreCallback (to set the flag ON)
and setPostcallback (to turn the flag OFF)

[Morphoice]

@d-healey I'm glad I'm not the only benefiting away from from the mess I caused. Unless you want all buttons off radio groups seem to be fine to use.

[Morphoice]

@Lindon aye! the playing never worked on the button press though. only ever on the preset load. I'll have to revisit the way I fired the note

[Morphoice]

@Lindon this was the way I did it before

   		Bass.asSampler().loadSampleMap(bassMaps[bassProms.indexOf(control)]);
   		Bass.setLoadingCallback(Synth.playNote(36,127));

and that only seems to fire on preset loading, not on the actual button use

@Morphoice You can…

1. Call it by function name (pass in the component as the first argument).

2. If you want the callback after a component value change, call onChanged(). Except if it's during onInit. That won't work.

3. Register the callback for use with a broadcaster. Then, trigger the broadcaster manually.
