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
