I’ve been confused by the EQ complaints, as well. Both the master EQ and the destructive sample EQ have worked for as long as I can remember.
I’ve never found the destructive sample EQ that useful, for lack of configurability, but this “no audible effect” meme has been repeated a few times here and on the Polyend forum and had me questioning if my own ears were deceiving me. Is it really possible I’ve been placebo EQ’ing samples all this time?
It is not.
Loaded up a saw wave sample, captured the un-eq’d frequency response on Logic’s Channel EQ analyzer.
Then applied a 12db boost on the Tracker’s sample EQ effect around 120Hz and 2000Hz.
This has a very obvious effect on the sound of the saw wave…it is clearly more nasal with a low end boost, kind of a quasi-formant sound.
As an A/B with a standard industry tool, we can also apply the same 12db boosts at the same frequencies using Logic’s channel EQ. I’ve had to guess at the Q-factors, but they sounded pretty narrow to me so I’ve gone with 4.00 for the low and mid/high boost.
As you can see in the frequency analysis curve, the boost from the Tracker’s EQ effect is quite similar in response to the Logic Pro EQ (perhaps it is slightly more drastic in the low end, though again, I’m guessing at the Q).
Mostly I’m relieved my ears still work
