i just gave it a try and made it work.
jvst library folder must go into the libraries folder as usual.
the dll files should be placed in the same folder as processing executable (when running from the IDE it searches processing's path, not your project's folder nor the /data). If you want to load the dll from a custom folder go with the full or relative path.
apart from that, you need exception handling and it runs.

1. import org.boris.jvst.struct.*;
2. import org.boris.jvst.constant.*;
3. import org.boris.jvst.*;
4. import org.boris.jvst.util.*;
5. void setup()
6. {
7.     try
8.     {
9.         //AEffect a = VST.load("C:\csound11_2f\bin\jvst\mda Delay.dll");
10.         AEffect a = VST.load( sketchPath("mda/mda Delay.dll") );
11.        
12.         a.open();
13.         a.setSampleRate( 44100.0f );
14.         a.setBlockSize( 512 );
15.         // attempt some processing
16.         int blocksize = 512;
17.         float[][] inputs = new float[a.numInputs][];
18.         for (int i = 0; i < a.numInputs; i++) {
19.             inputs[i] = new float[blocksize];
20.             for (int j = 0; j < blocksize; j++)
21.                 inputs[i][j] = (float) Math
22.                         .sin(j * Math.PI * 2 * 440 / 44100.0);
23.         }
24.         float[][] outputs = new float[a.numOutputs][];
25.         for (int i = 0; i < a.numOutputs; i++) {
26.             outputs[i] = new float[blocksize];
27.             for (int j = 0; j < blocksize; j++)
28.                 outputs[i][j] = 0;
29.         }
30.         a.processReplacing(inputs, outputs, blocksize);
31.         VST.dispose(a);
32.        
33.     } catch( Exception e )
34.     {
35.         e.printStackTrace();
36.     }
37. }

wow thanks...  I will give this a shot.

i've updated the example above to load dll files from  "yourprojec\mda\ ........dll"

have fun

I will check to see if the source is the same as I last checked :)

i have used the package you have linked above. so it's the same

path problem ??  I have more than one install of processing could that be it??

2 ways. place the jvst library inside "processing\libraries" folder.
or place it inside the path that is defined in your processing's preferences.

if you go to File / Preferences you will know where it is.

i am using version 1.2, not sure if jvst is ready for older versions.

I have three or 4 of them on my computer..  I renamed the one I wanted to use processing2 and then chose that as how I wanted to open the files and now I am getting, looks like it is giving the original name of the library befour I renamed it..

you misplaced the jvst library again it seems to me..

hello,

i was wondering once i get the vst to run ( i used the sample mda delay.dll ), how can i interact with it?
how can i change its parameters and how do i apply it to existing sounds if it is an effect vst and how do i use it
to create sounds if it is a synthesizer vst.

when i run pixelnerve's code i get the console message "Callback : 1, 0, 0, 0, 0.0" but i dont know what that means

has anyone succesfully used jvst in processing?

hey guys,

anyone got luck in loading it with the gui of vst itself ? any help? would be very nice.

thanks
k.m.
