I believe I had the exact same question a few days ago 🙂  
[https://forum-next.cabbageaudio.com/t/cabbagegetvalue-in-a-k-rate-loop/2726](https://forum-next.cabbageaudio.com/t/cabbagegetvalue-in-a-k-rate-loop/2726)

Btw. `cabbageGetWidgetChannels` works only at i-rate and retrieves an array of strings.  
`chngetk` works on arrays though…

I’d also like to detect which element of an array changed and not only that but also detect crossing thresholds like in the `trigger` opcode but on arrays.
