@tiesvdam the solution already exists in the Custom Sample Import in the HISE tutorials. Check out the Scripts/LoopPointDragger.js it has everything you need.

Basically the best way to do this is to just use a panel and overlay it ontop of the audio waveform. You can use a paint routine and mouse callback to set the sample & the loop start and end points.

It's better to share the HISE snippet for future reference. Here is an example but mine is quite buggy:

Slightly off topic question, but doesn't the sampler kill active voices and cause an audio dropout when you adjust a samples parameters like the start/end for the sample or the loop region???

@tiesvdam This post has some documentation about editing and accessing sample properties - it's a little out of date so if something doesn't quite work you might need to check in the docs - https://forum.hise.audio/topic/64/fun-with-regex

Also take a look at the custom sample import project - https://github.com/christophhart/hise_tutorial/tree/master/CustomSampleImport

@d-healey Ah okay thanks for all the info en help!

@Gab Ah perfect, im gonna try! Thanks!!!

@tiesvdam I don't think this is related to the preset browser.

Start with Christoph's custom sample import example project - it's quite complicated though.

@d-healey Yes sir

@tiesvdam and you can add the icon as an icon font or svg and then color it in this laf

@d-healey Thanks! fixed it. Love your help everytime

@tiesvdam 👍

@mmprod Yes i think that will fix it, i will try it today. Thanks for the help!

@tiesvdam I don't think you can get rid of it, I solved it by painting the path in a panel, and removing the "extra line" parts by manipulating the path string
The moving ball is from the envelope floating tile but the rest is a painted panel

it involves converting the path to string - remove certain strings - convert it back

I hope there is a better way to do it, but I don't know if there is any.
Anybody knows how to do it in a less cumbersome way?

this is part of the string manipulation, p is the path

var a = p.toString().split(" "); var ax = parseInt(a[6]); var ay = parseInt(a[7]); var acx = parseInt(a[4]); var acy = parseInt(a[5]); var dx = ax + (parseInt(a[14])-ax)*0.95; var dy = parseInt(a[15]); var sx = parseInt(a[17]); var sy = parseInt(a[13]); var rx = parseInt(a[22]); var ry = this.getHeight()-3; var str = a.join("\n"); var path = Content.createPath(); path.fromString(str); g.setColour(Colours.chartreuse); g.drawPath(path, path.getBounds(1), 1.0);

@tiesvdam That's not quite how look and feel is used.

Check out this video, but replace Engine.createGlobalScriptLookAndFeel() with Content.createLocalLookAndFeel()

@tiesvdam fixed it already thanks!
