Clarification: when I say you can't substitute "one" for the other, I mean trying to substitute [osc~] for [cos~].

From what I recall

[osc~]

is the same as

[phasor~]

[cos~]

So while there may be some trivial instances where you can substitute one for the other, generally you can't.  For example-- imagine having some more tilde objects between the [phasor~] and the [cos~] above.  In that case you cannot get the same signal using [osc~].  (Or at least it's not obvious to me how one would do that.)

Furthermore, the right inlet of [osc~] is a control inlet, while the inlet for [cos~] is a signal inlet.

Most of this info should be in the help patches.  (At least the ones I made for Pd Extended.)

Hey Seb,

Good to hear from you...

Does [osc~] take arguments? In my test when I gave the patch an [osc~ 0] I got an error in the console saying '0' not understood and I presumed that was my argument being spat back.

I can't really explain why it doesn't sound right to be honest, this is why I'm here asking:).

I need to do some more coding and get back to you on that one.

Regards,

Julian

Hi Julian,

I've never used [cos~], can you explain to me why an [osc~] with the correct phase cannot do the trick?

Cheers

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..
