Last night I found another, similar but simpler solution shown in the
attached patch. It adds something to the phasor to get a shifted
signal and then uses [>~ 1] from zexy (I think) to check, if the
shifted sig goes beyond 1. If it does, I substract 1, which is the
result of [>~ 1] if it's true, otherwise I substract 0, which is the
result of [>~ 1] if that's false. This works for a phasor~ but not for
other oscillating objects like the osc~, but here it's okay. 

So now, trisaw~ is a working triangle to up/down-saw morphing
oscillator, that even should be bandlimited, if I understand the used
algorithm (taken from a Istvan Varga Csound instrument) correctly. 

ciao,
