does anybody know how to make an up-down saw-wave ?
a triangle oscillator?
phasor~ just ramps up and then goes straight back to 0, but i want
something that ramps up then back down again.
i know it's possible to use a [metro] and [line~] based solution, but
that falls apart at high frequencies. is there a way to do this in
the signal domain?

abs~
[abs~] is part of zexy. if you need a solution only with internals, see
frank's solution.
well, abs~ is now part of zexy abstraction. it's made with expr~.
all this equation can be made with expr~.
but using a table should be faster.
