Hello I am interested in writing a Runge-Kutta ugen for numerical integration. A few questions before I dive in... 1) Has someone out there already written one? 2) Will the performance of this Ugen be good enough to even attempt this? (ChucK is quite slow at runtime) 3) Is a ugen the proper place to do this processing - perhaps I need to write another sort of object? My thought is that a class using this ugen would be advancing something like 1::sample => now, and the output of the ugen could sent to the dac... The ugen would need accept arrays and output arrays... is this possible? And what about the function it will need to perform the operation on? Can this be fed into a ugen? Thoughts on how this would be possible? Thanks in advance, David
