How to delete unused dsp

Is there anyway to delete unused dsp effects in renoise, similar to the delete unused patterns function?

Hi,
i’m interested in how can one determine for sure if a DSP is unused?
checking its state (toggled off?) or being on a track without audio signal?

Unused DSP = DSP’s which are never turned on.

ffx proposed a way to do it here: How to find unused DSP's in a song?

Would love a tool for this but I’m not capable of making one myself.

it should be an option within renoise itself really

You can now get a list of unused DSP’s with one of Ledger’s tools. It’s very useful.
