i sometimes used the attached idiom, which works in certain circumstances. (using the [max] object).

for such counting i typically use [value]. as in:

[loadbang] | [t b b] | [value foo] | [+1] | [value foo] | [delay 0] [value foo] |

with "foo" being replaced by some unique symbol shared among all instances.

this is of course more useful outside of [clone] (where christof's suggestions is much nicer), e.g. when dealing with multiple GOP-abstractions.

I can imagine adding a flag to [clone] to automatically pass the number of instances as the second argument:

[clone -n foo 20] == [clone foo 20 20]

but I'm not sure it's worth it...

well. otoh it looks quite elegant inside the cloned abstraction: $1 - id of current instance $2 - number of instances $3... - other args

i can't think of an interface to get the total number of instances inside the abstraction that is not much, much uglier.

somethiung like

[clones( | [pdcontrol] |

Yes, that's the only way.

Thanks Christof.

I would like to avoid this if possible.

Why? Is it only for cosmetic reasons, or for technical reasons?

Yes, mostly aesthetics. It seems redundant. It creates extra work. It would simply my development workflow.

I'm communicating to my clones via arrays. Each clone reads values from certain arrays, and writes values to other arrays.

(In the output case, the clone instance number always corresponds to the array element number, so I can see what each clone is doing. On the input case, I'm reading at audio rate

So when I change the number of clones, I must change this in the 2 places you've mentioned. I also have to resize my arrays, which requires changing at least 1 message. (I imagine that I can probably change all my arrays using a single compound message, but haven't tried this yet).

Ideally, it would be nice to change N in *one place*. I think this might be possible if the first feature was implemented.

e.g., "If I am instance #1, and the number of instances has changed since last time (stored in a global variable), then resize my arrays".

Yes, [clone foo 20 20] might look ugly, but it does the job. Personally, I

haven't ever needed the number of cloned instances inside an instance...

I am still working on converting my 12 band flanger/auto panner to an N-band Flanger using clone.

If we think about the clones spreading out and creating an equal phase displacement across all N bands, and if we let S be the instance number, then we can calculate the phase displacement for an arbitrary instance like this:

PhaseDisplacement(S) = (2π / N) * S So each clone needs to know the value of both S ($1) and N.

but if you need it frequently, you can make a feature request on GitHub.

I think I will, thanks!

Is there a way for a clone instance to determine the total number of clones?

Because often the behavior of a clone depends on its relative position within a chain of instances.

"I am instance 12 of 100, therefore, I should behave like so...."

I find myself passing in the number of total clones as a parameter. I would like to avoid this if possible.

Thanks, BH
