I want to find some way of controlling various parameters via the keyboard. The problem I'm having is that in order to write some sort of generic class that can change arbitrary UGen parameters (or really anything), one needs to know what types your dealing with. Is there a way of asking chuck what things are? For instance, I can maintain some sort of list of UGens I want to control via an array of UGens, but then when I attempt to access a parameter on one of the objects in that array, it tells me there is no such member in class UGen. THe idea is that the array would contain references to various UGens I want to manipulate, and they may be of any UGen subtype. However, in order to access any members, the compiler needs to know exactly which type each object is. Any ideas? -- Rich
