Hi Chris A, #1 post here!
"Once you've determined that your track has a missing bass octave, select Effects --> Equalize... then notice a curve pops up. Here is where you will open one of the example bass boost xml files that you found above in this thread, by clicking on the "Save/Manage Curves" button at the middle-bottom of the curve window. Import that xml file by hitting the "import" button and searching for the sml file that you've saved locally on hard disc. You should see the curve appear when you select if from the list. Hit "ok" to close the curve management window, then "ok" again to close and execute the Equalize... filter. You will see the traces change shape - perhaps even turn red, etc."
Keen to explore this & started with Bromberg 'crabtree', given I was already impressed with the bottom end. But, ran into an issue at the "Save/Manage" stage of importing your xml file. Using a mac & just can't locate the sml file ...?
