Thanks, I got it!

However…

… that’s not what I found in this little test, a few years ago:

And HighPass and LowPass are legacy (for retro-compatibility), so maybe better to avoid them… I just did a little test with 20 effects of each on a single event, and Multiband EQ seems cheaper on the CPU. Here’s the result: But maybe with different settings, the result would change, I don’t know… Nobody can answer but you. Just try! (but I would tend to say it’s often possible)

Which is why I thought multiband EQ generally was the best choice.
