Hello George, You have an interesting point there. I wanted to suggest to you that you wrap your BlitSaw in an extension of a Chubgraph class, but that also doesn't work! It appears to me that Chuck in general doesn't let you assign arrays from subclasses to superclasses: a bit of a surprise indeed! For example : class ClassA { float v; fun float value() { return v; } } class ClassB extends ClassA { fun float value() { return v * 2; } } ClassA myObjectA; ClassB myObjectB; //ChucK allows: myObjectB @=> myObjectA; //but does not for arrays :-( ClassA myObjectArrayA[10]; ClassB myObjectArrayB[10]; myObjectArrayB @=> myObjectArrayA; // gives error Of course there are less pretty ways of achieving what you need, probably by just switching the routing of the UGens : BlitSaw blitSaw[10]; BlitSquare blitSquare[10]; Gain output; // => or the rest of your patch for (int i;i output; blitSaw[i] => output; } for (int i;i output; blitSquare[i] => output; } Happy chucking!

1. how do I assign a Blit array with a BlitSquare array? (George Locke)

Hi,

I have a class that I want to use either (multiple) BlitSquare or BlitSaw oscillators, where i can switch between them during performance. I thought the easiest way would be to have a single Blit array that holds either, but apparently I can't do this:

BlitSquare pls[10]; BlitSaw saw[10]; Blit osc[10]; if (choosePulse) { pls @=> osc; } else { saw @=> osc; }

Any suggestions?

How is the Blit type ever to be used if not in this way?

(My chuck experience is limited, but I am an experienced programmer.)

Regards, George
