ACX plug in not working


It appears that my ACX plug in is not working for tracks over 30 mins. :open_mouth: It shows process complete but can’t see any results. Is it just me or is this a bug?

Please help.



Ensure that you are using the current version of “ACX Check”.
The current version is available here:

Hiya Steve

I hope you are well.

Sorry dummy question. How will I know what ACX plug in version I have? I went to the link you provided and I can only get a txt file of the ACX plug in. Sorry to be a nuisance.


That “text” file IS the plug-in.
It “should” have a file extension of “.ny”, though Macs often add “.txt” to the name when you save it.

If you post a screenshot I can tell you straight away.

Hi Steve

Thought I check it out before I get back to you but I just can’t crack it! Sending you few screenshots, hope this will help.

Please help.

ACX Check is a “Nyquist plug-in” and it needs to be installed. Instructions here:
You may need to enable the option “Allow overwriting” (see:

Please note in your screen shot the filename is wrong. Take off the dot txt.

Other than that, it seems to be the right one.


Ideally, yes, but the “Nyquist Plug-in Installer” does that automatically.

Hi Steve and Koz

Thank you for taking time to look at this. I will go over my ACX plug in, do your suggestions and fingers crossed this get sorted.



Hi to you both

Looks like the ACX check plug in I have is an old one. I downloaded the ACX check from the link you provided, change the file name to ny and vola, it worked! Screenshot attached.

Thank you so much!
