the problem is that when I add more than 3 sampler the 4rd sampler doesn´t work , not produce any sound and oviously have it! but without close the Project I add again the samples in each "SAMPLER" ( 4rd, 5th... ) I can hear again this sampler .. until I close the project and the HISE software Why is That ?

@d-healey ok honestly I don't understand when you say defer ..

What's mean that ? I'm a little lost in that part

@d-healey ok that's better so when I do that and it works, I'll do a video tutorial explaining how to make an instrument of this type xD .. may return earlier than expected here

ok how I do my own key switching system? xD

Is there any way to switch sampler with midi controller? no samplemap

If a have 8 sampler ( each sampler with diference sounds of course) How I switch this sampler with midi controller ?

ok my point is . In kontakt 5 I can create a Instrument Bank and in each space drag and drop for examble in the 1st rectangule a Trumpet sound and 2nd rectangule a Piano sound ..... So them I can assign a range of keys to change the instrument for example C1-C#1 so when I press C1 I'm going to have the first instrument "Trumpet" when I press C#1 Piano instrument ... Actually I want to create a Hammond s6 standalone instrument , the thing is that organ have many Registers of sound the same Organ and to change that registers have it many buttons of course the real organ! but this organ only have 4 octave F2 to F5 so I can use others key of my midi controller to change this registers

ok but that I want and I need is something to play on live and change the sounds when you press a key or specific note on midi controller , Can I do that with buttons like you say?

My samplemap's name is "solo campana" how I Call this samplemap

{
Sampler.loadSampleMap(solo campana);
}

function onController()
{
var noteNumber = Message.getNoteNumber();

Console.print(""+noteNumber);

if(noteNumber == 43)
{
    Sampler.loadSampleMap(Pato);
}

if(noteNumber == 45)
{
    Sampler.loadSampleMap(solocampana);
}

}

of course doesn't work . I don't know How to call a samplemap or maybe , call another sampler it work too

I have to download vs2017 ?
