Displaying a waveform from a sampler

[Lindon]

@d-healey thanks, yes trying that as we speak - but I cant see any way to load a sample into it (the drag and drop doesnt work neither does right clicking) and I cat see any attributes I can use to set it up...:-(

[d.healey]

@Lindon Did you check the doc I posted?

[Lindon]

@d-healey yeah- thanks - but its not really much use to me as I have over 500 kick drum samples the user can select from - and I want to display the one they have chosen...so pool loading them all will break the heap space pretty quickly...

[d.healey]

Can't you change which one is loaded into the audio player through scripting at run time?

I haven't played with it before, I have to go out in a minute but I'll try it out when I'm home.

[d.healey]

audioSampleProcessor.loadFile() Looks like a good place to start.

[Lindon]

@d-healey yeah - but this is my exact problem - I would need to ship all the audio files as compressed audio with their associated sample maps(500 sample maps) AND ship all the audio(wav files) again as load-able into an audioSampleProcessor. These would need to be pooled so I think this number would break the heap space limits in the windows compiler.

Meanwhile the sampler already has this data and can display it how I'd like - but I cant get to it (Sampler>Sample Editor)

[d.healey]

@Lindon Ah I see, I was thinking the loop player could load from sample maps. @Christoph-Hart - feature request :)

Secret tip of the day: use the sampleIndex property if you want to display samples from a samplemap in the audiowaveform.

Load any samplemap into the Sampler1, then press Refresh and you'll see the exact sample you've selected.

[Lindon]

@Christoph-Hart well yes, and no.....

When I make a sample map and create a ch1 file for it and then load this (ready to ship) sample map - the audioWavewForm doesnt refresh at all... :-(

[Christoph Hart]

Have you selected a sample in the combobox?

[Lindon]

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

[Lindon]

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...

[ustk]

@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 ....
