Is there anyway to avoid using [fexpr~] and make it still function the same?
For Example, I want an abstraction or subpatch that functions the same as
fexpr~ $x2*$x1 + $x3*$x1[-1] + $x4*$x1[-2] - $x5*$y1[-1] - $x6*$y1[-2]
Is it even possible?
I'm asking this question because I'm developing an iOS app using pd and I've heard Apple doesn't allow me to use GPL license stuff such as expr~, fexpr~.
Any help please?
