There are probably a lot more ways to implement ramps. For example, youcould increment only at block boundaries and just repeat that value for therest of the block. That would looks a lot like Supercollider's "kr" ugens. (Iactually thought that's how [line~] worked until I looked at the code.) Btw-- does it cost anything significant to dereference x->x_inc inside thewhile loop of line_tilde_perform? Or is the compiler able to somehowoptimize that? -Jonathan

Hi, me again. Thanks for the discussion. It has really opened my eyes. So, i got my naive c++ implementation of line~ basically working. And of course, just running a for loop incrementing by ticks, i run into the exact precision error that this block quantizing seems to avoid. My line from 0 to 100 over 44100 samples only gets to 99.93 So, i also need to add something like pd's block quantization to make sure my line goes all the way to the specified value. My questions then are 2: Is pd's method the way i should do it? Or is there a better alternative? And, if i do it the pd way, how does that work? Does the increment get updated every block? Or is it just the last block that is stretched?
