That would be nice to have as an outlet from an array. Or perhaps the [table] object should have an outlet to get that info.

Pd-l2ork has a feature where you can [r "arrayname_changed"]

If you want a notification when using tabwrite/etc., well, when those
objects receive a message to update the array, just manually send
a bang to "arrayname_changed" when this happens.

Hi all
Is there a way to be reliably notified when a table/array changes? My hope is that I don't know of some hidden feature. Is there any?
It's easy to catch messages sent to [s arrayname]. However, it's not so easy when data is written through [tabwrite arrayname] or [tabwrite~ arrayname] or if the data is drawn manually.
My current solution is quite a CPU hog: The whole table is scanned in periodic intervals and compared to a reference table, so that any difference will be caught. Of course, this solution comes with a latency (it's a trade-off between avoiding latency and saving CPU cycles). Probably, it could be a wee bit less CPU hungry to make the comparison in the audio domain instead of the message domain, but still it's work-around.
Is there a real solution for this around?
