Displaying a waveform from a sampler

[Christoph Hart]

Have you selected a sample in the combobox?

@Christoph-Hart yep that fixed it - silly me . Thanks.

OK so for those of us trying to use this in any practical scenario - there's a couple of gotchas.....

So assuming a scenario where you want to load a sample map and display the audio at the same index position in all cases, so for example you have a set of hundreds of drum sample maps, each with just one wav file (at index zero obviously..).

So you swap out and load the new sample map and say:

AudioWaveform1.set("sampleIndex", 0);

and you will (sadly) discover your AudioWaveform will not display the new wav file...

The only way around this that I've found (and its sorta ugly) is to:

• set the AudioWaveform to some other index position (even if theres no file at that position) e.g.

AudioWaveform1.set("sampleIndex", 1);

• wait for it to set itself up...(use a timer) and then reapply:

AudioWaveform1.set("sampleIndex", 0);

You cannot do this:

AudioWaveform1.set("sampleIndex", 1);
AudioWaveform1.set("sampleIndex", 0);

As again it fails to work

Here's my snippet of this cough "solution" at work... if any one has a better way of doing this please let me know...

@Lindon I don't know much on this side.
But maybe Engine.getPreloadProgress() can help you?

[Lindon]

@ustk - thanks - I looked at the API - just one question "the progress of what?"

[ustk]

@Lindon preload :)

[Lindon]

@ustk lol - yes - the preload progress of what? The Sample Map? The AudioWaveForm ? my washingmachine?

and once i know what this is Im not sure how this helps me in any real way....

Actually this is a bit dis-ingenuouse of me..sorry. Yeah waiting for the sample map to load might be what I need - but I think what we need here... but its working right now so once I need to laod a bigger sample map and thus need some sort of async. call back method I think I might ask for that...

Hey @Christoph-Hart - how about it:

on async(event)

(just half joking here...)

[ustk]

@Lindon Apparently, it's the progress when loading samplemaps (maybe just audio samples too? don't know...) Sorry man that's all I know

[ustk]

@ustk Maybe just to replace your timer with something cleaner... Again, that's a side of Hise I don't really know...

[Lindon]

@ustk yeah on async is the cleanest code solution ....
