I agree with the above. I'll just add that it depends also a great deal
on what else is in the recording. Perhaps masking or compressing the
triangle wouldn't impede that much on other instruments, depending what
they are: if you've got a fiddle, you're pretty much out of luck.
Anyway, as to your main question, there are plenty of tools, if only you
can identify the frequency: multiband compression and parallel procesing
both come to mind.

A friend has discovered some historical
recordings of his Grandfather in
the Smithsonian's collection, and would like us to clean them up a bit for
publication. One of the issues is that the triangle player is often off
the beat with the rest of the band, and he would like us to push the
triangle to the back of the mix.
Is there a plugin something like a compressor coupled to a notch or comb
filter that I could use to suppress the sound of the triangle within a
recording of a Cajun band?
Hi,
sadly it's not sooo simple to supress a single instrument from a mix. A
triangle is pretty narrowbanded though, so one could maybe get away with a
narrow notch filter. But the more problematic part is the attack phase of the
triangle. It is rather wide spectrum (compared to the tail) and sadly the
attack phase is what defines its rhythm.
Maybe there's research out there though. If you had a model of the triangle
sound there might be ways of a] detecting where a triangle note is played and
b] basically subtract the model prediction from the audio signal at that
point..
Have fun,
Flo
