if you ears aren't quite good enough ...
Here is the EQ graph for my kick drum:

You can see that it is peaking on E. Now, I want it to be tuned down to C. To help me I positioned a EQ band (with 0 dB gain) at the desired pitch, then retuned the note in my sampler until its peak was where I wanted:

You can see that I have zoomed in to the lower frequencies, displayed a keyboard (from the 'Area' menu) and enabled track peaks, Average and Maximum in the 'Settings' menu, Graphs tab.
Or course, you could do this with MAnalyzer too.
For Toms, try tuning them to the scale root, 3rd and 5th. And for the Snare - to the 5th too.
