Groups for Duo

[beatleboy07]

Hello list,

I am working with another individual, and we're going to be performing as a duo in the coming weeks, and I'm using sc to make different effects for us to both use.  I'm using a foot controller to turn things on and off for each of us, but I've run into one problem here.

I want to use PitchShift to make interesting choruses and harmonies on the spot.  I have it simply set up as this:

SynthDef("chorus", {
    Out.ar(
        0,
        PitchShift.ar(
            In.ar(0, 1),
            0.1,
            1,
            0,
            0.004)
       
        +
       
        PitchShift.ar(
            In.ar(0, 1),
            0.1,
            1.5,
            0,
            0.004)
       
        +
       
        PitchShift.ar(
            In.ar(0, 1),
            0.1,
            2,
            0,
            0.004)
        )
    }).send(s);

MIDIIn.noteOn = {arg src, chan, num, vel;
    if(num == 48, {~synth1.free; ~synth1 = Synth.head(s, "distortion1", [\distortion, 100,\thresHold, 0.0003, \bus1, ~controller1.index]) });
   
    if(num == 50, {~synth1.free; ~synth1 = Synth.head(s, "wahWah", [\thresHold, 0.0003, \bus1, ~controller1.index, \volume, 3]) });
   
    if(num == 51, {~synth2 = Synth.tail(s,"chorus", [\thresHold, 0.0003, \bus1, ~controller1.index]) });
     
    };

MIDIIn.noteOff = {arg src, chan, num, vel;
    if(num == 51, {~synth2.free})
    };


    )


This works fine when I perform alone and have control over when I use the chorus and when I don't.  However, if I am using the distortion, and I don't want the chorus applied to it, but my duo partner wants a chorus applied to what she's doing, it gets more complicated.  It seems like a group is the best idea for this, but I can't quite see how I could set it up so one of us can apply this chorus effect to our own material without affecting the other material.  Or is there a device that can have In search for a specific variable (i.e. ~synth1 or ~synth2)?

Thanks for the help!
