hi,
there is an old vex external, too. This one computes any gen of the saol set: harm, harm_phase, periodic, buzz, step, lineseg, expseg, spline, cubicseg, sample, empty, data, polynomial, concat, random, window. It has options for guard points to be observed, operations to be restricted to an array's subrange, resizing, normalizing, etc.

For more of the classic Gen-functions you need to look into external collections. PeRColate has several of them, and I think, vasp as well.
