Spondes

I'm working with Java in Max MSP and i have created a delay effect. What i want to do now is be able to pan the original audio where i want but leave the delayed audio as it is.

Obviously I need to first create a second output for my Max Java Object which i have a rough idea on how to do but, I'm not sure on where i need to go after that.

If anyone could help me I would be more than grateful. I can send my code so far if anyone needs a look.

This is a very easy thing to do. What do you think is holding you up? It's just a matter of creating a class that extends MSPPerformer (which Max will do for you), then writing about four or five lines of trivial code.

I can't make my Max work properly at the moment (see other post). But, this is approximately what you want, I believe.

Please do not hand my code in as an assignment, if it's an assignment. That would be plagiarism. I'm just showing you the techniques that I use, and I hope you can learn from this example.

This is a bit more fancy than I mentioned above, but is still a trivial program. It just shows you how easy Java is to use with Max/MSP.

I can't upload java to this forum??!?!?!!?! I'll rename it as .txt

I'm having a £*$£$ day of it. I can't test the above program, and just noticed that it doesn't copy the input into the delay line. This might work :(

public class delayPanAudio extends MSPPerformer

    private static final String[] INLET_ASSIST = new String[]{

        "input (sig) + pan (float)", "mix (float)"

    private static final String[] OUTLET_ASSIST = new String[]{

        "left (sig)", "right (sig)"

        declareInlets(new int[]{SIGNAL,DataTypes.FLOAT});

        declareOutlets(new int[]{SIGNAL,SIGNAL});

        setInletAssist(INLET_ASSIST);

        setOutletAssist(OUTLET_ASSIST);

    public void dspsetup(MSPSignal[] ins, MSPSignal[] outs)

    public void perform(MSPSignal[] ins, MSPSignal[] outs)

        float[] out1 = outs[0].vec;

        float[] out2 = outs[1].vec;

        for(i = 0; i < in.length;i++)

         float delayed = delay[ cursor ];

     float pannedRight = in[i] * (1.0f-pan);

         out1[i] = pannedLeft * (1.0f-mix) + delayed * mix;

         out2[i] = pannedRight * (1.0f-mix) + delayed * mix;
