@esaruoho I sent this while you were replying and might of skipped it

the bang between [r $1-id] and [array get plom$1] looks like it is blocking the id, and the delay is toggling the metro twice

the bang between [r $1-id] and [array get plom$1] looks like it is blocking the id, and the delay is toggling the metro twice

are all the arrays the same size?

Did you close the edit window with the "done" bang?
If not the metro will still keep updating the last array that opened it.

@esaruoho said:

am now trying to figure out how [vis 0( could also be used to control the windowsize + position of the array edit, since having it stably in a specific place would be pretty amazing.

@esaruoho Well, this is possible with the now undocumented message [relocate( which is not at all intuitive and may disappear sometime in the future, however it still works at the moment.
It is in the Pd-extended documentation but has disappeared in later releases of Pd

No warranties for the next bit
so make back ups or use a copy of your patch

Copy the four objects and paste them in your patch if you want to test, click the bang and the $0-edit subpatch should open at size of 720x530 at the position of 50 left 50 top (adjust the message list to suit.
[menuclose( is required instead of [vis 0( for it to work

@esaruoho sorry for the late reply I'm in Australia, but it looks like you have it sorted anyway
cheers

Another method is to use [array get] and [array set] and copy the array to a larger editor array and back to the calling array with a metro to update as you edit.
Here i've used an hslider to blackout the arrayname but also receive a click to open the editor and send its id.
setget.pd

PlugData does have GraphOnParent under the + symbol at the top (or ctrl+shift+G) which produces an empty GOP subpatch that work perfectly and is sizable rectangle, right click this to open and edit

You divide the array size by the samplerate to get the number of seconds

Here is the updated poly version
