Some good stuff here, thanks people.

[osc~] doesn't appear to take arguments so that's out.
I don't doubt Alexandre's ears or thoroughness but in this instance,when replacing [cos~] with [osc~] there's a big difference in the sound.
Alexandros - thanks for the sketch, yes it does make sense, webpd has no [until] or [cos].
Joe- nice implementation, again unfortunately there's no [abs~] or [wrap~].

What I do think from the hints and suggestions given is that I've got enough to be getting on with to make something approximately close and hopefully interesting.

Thanks all for suggestions so far,

Julian

Hi Julian,

I've attached an optimised implementation for [cos~] that we've been using for Heavy. It's an approximate taylor series expansion but it should be much faster than just using cosf(). Hopefully webpd supports [abs~] and [wrap~].

Cheers,
Joe

what about this?

well, ASCII patches don't look so good, but I hope you get the picture.

cause I made some tests, [osc~] will give the same result as [cos~]...

how is that?

Alexandre & Alexandros,

Cheers for pitching in.

It's for a random bleepy patch. 
Unfortunately [osc~] doesn't have the tonal quality I'm after - good idea though.

you can treat [osc~] as [cos~]

just give it a frequency of "0" and use the phase inlet as the angle input (from 0 to 1). 
But the phase inlet of [osc~] is a control inlet, and [cos~] takes signals..
