@Lindon told ya

Right built the plugin - loaded it into Reaper - crashes...

now to build using Dan K.'s video tutorial...

[Lindon]

Okay I think I may be getting somewhere....

So I THINK I'm getting an access violation on the paint of the SAmplerSoundWaveform:

But if I sound clueless - I am - but it keeps coming back here no matter what I do...

[Lindon]

@Lindon Ok so I took out the AudioWaveform controls - and the plugin works fine - so there's a bug in the rendering of this control I think...

@Christoph-Hart !!! Help!!!

Are you using a custom look and feel for the audio rendering?

nope - everything else just about but not that.

I am redrawing them(changing their colours) a fair bit though to reflect their position in the XY pad space...

@Lindon OK well I tried a custom LAF and that doenst fix this issue.

It seems to crash every time I've played a note (and thus set the play head somewhere) and then I scroll thru the list of voices -- I have no idea why its doing it at that point.... I can (obviously) let you have the project if you want @Christoph-Hart

@Lindon can you dumb it down to a minimal example or is it only happening with your project?

Ill try and get it down to something manageable...

Well frustratingly I cant reproduce the problem in a simplified project....

its maddening.... I can open the UI, open the viewport and scroll away, and select items... and everything works correctly... I play a note, open the viewport , scroll any amount - and the system gives me the "circling- busy mouse icon" and it crashes...

[Lindon]

@Christoph-Hart - there is no event taking place on the viewport scroll is there? There's nothing happening in the HISEScript...

Yes it communicates to the audio thumbnail class which range to create a path for and spawns the waveform calculation on a background thread.

Alright, send me over this bad boy and I'll try to reproduce it. If you can limit the amount of samples I have to download or remove some parts that don't affect the functionality it would be great.

found it I think --- the viewport works fine for a hundred items, but crashes everytime when I add in all 1500 items.....

nope now its working fine... grrr...hang on chasing down a couple of other possibilities - if they dont pan out it will be over to you...

sigh oh dear - I've got it a bit more reliable - pretty much in the end all I did was replace the viewport with another and copied over the code from the CB....so its over to you I'm afraid.... I PM you the download URL....

[Lindon]

Ok yet more testing...

Now I added a viewport, and put a panel in it.. and wrote the sample map names --- no on mouse callback - its doing nothing

-- compile, load in reaper, play a note - go to the browser - scroll the new viewport - ---- crash.

[Lindon]

@Lindon Ok got some debug info. out of VS, again Im just moving the viewport scroll bar..

..and its still telling me there are problems in the SamplerSoundWaveform::paint

[Lindon]

bump bump?
