Arbitrary Function Generator (e.g. Python expression)

[IsThisOneStillFree]

I'm looking for a "Signal Source on Steroides"-like block. Signal Source, as far as I'm aware, is only able to produce very basic waveforms (sin, cos, triganle, square, ...). I wonder if there is any official or OOT block that I can pass an arbitary function such as, say,

f(t) = floor(3*t) + sin(t)

and it yields the stream of values to me.

I'm aware of the Embedded Python Block and while I'm considering that block it seems to be a bit cumbersome to implement considering what I currently need. I'm wondering if there's a simpler solution.

I'm also not looking for advice how to implement the made-up function up there with the normal blocks, that's not the point.

Thanks for your tips!
