Hello, Ardour doesn’t detect Tunefish4.so. Is there some issue with this particular synth or am I doing something wrong? it’s in the same folder as all my other plugins. Many thanks


It should work, at least it works on my machine. Did you check the “instrument” button in the plugin manager?


yes, I can use pretty much any other vst from the same folder. If I clear the blacklist and cache and scan again I see ‘tunefish4.so’ in the scan window but it still doesn’t come up in the plugin manager…


I have it in my home directory. Maybe try this:

I don’t see any permission differences to other vsts that work fine. I found the blacklist in .cache/ardour5 and I see that it is blacklisted. How do I find out why it has been blacklisted? Is there a log?


Remove the blacklist and try it again and see if it works? Also have you checked 32 bit vs 64 bit for the plugins that work vs the ones that don’t?



I removed the cache and blacklist, downloaded all versions that I could (tunefish 4 64 bit, tunefish 3 64 and 32 bit) and the only one that wasn’t blacklisted and works fine is tunefish 3 64 bit.

Any ideas why tunefish 3 32bit and tunefish 4 64 bit are being blacklisted?


32 Bit probably just because it is 32 Bit, sounds like you have a 64 Bit version of Ardour.

Can’t speak to the 64 Bit Tunefish v4 though, don’t have it to test sorry.



You could try starting ardour from the terminal and logging the messages it outputs as it scans for plugins, may give some useful message.


thanks but unfortunately nothing appears in the terminal regarding the vst scan


In my case v4.2.0 and v4.1.0 - do not work (I mean ardour doesn’t find them).

Only version 4.0.1 (May 5th 2014) is found well and works fine.
BTW version 3.3 works good. The versions 4.0.1 & 3.3 - can be loaded simultaneously in one session.
Just put them into folder /usr/lib/vst.

My system is 64bit (KXStudio 14.04, Ardour 5.12.0), so I downloaded “tunefish-v4.0.1-linux64-vst24”, “tunefish-v3.3-linux64-vst24” from here:


Automations are working (at my raw test).


Just tested 4.0.1 and it works fine, thanks cooltehno! I wonder what’s wrong with the newer one…


I don’t know if it’s the problem but one glaring difference between v4.0.1/v3.3 and v4.1.0/v4.2.0 is that the former call the .so tunefish4 and the latter call it Tunefish4.

Try renaming Tunefish4.so to tunefish4.so and see if it starts working.


I’ve asked a question in github:


@peder: In my case renaming doesn’t take an effect.
