You're talking about the Synth Bass Drum, not the Physical Bass Drum, right? It's a frequency dial (not a note dial), so getting the right note is a bit difficult. The dial spans two octaves starting at approximately F0. So, for example:

-63 ≈ F0 (21.827 Hz)
+0 ≈ F1 (43.654 Hz)
+35 ≈ C1 (65.406 Hz)
+63 ≈ F2 (87.307 Hz)

It's fairly easy to tune it by ear for values above 0, but for the lower notes, you'd probably have to use a frequency-to-note chart or a spectrum analyzer.
