LT Spice will also provide some of this operational modeling. I have not used Leap, but inputting variable states in LT Spice will provide you with all of the linear state information you could want. Naturally music has no linear states.....

Putting a gap in an inductor just reduces the magnitude of the change in inductance, from X 10 to X 2, and of course there is the non linear response to frequency to consider, along with the amplitude, multiplied by the permeability curve, mitigated by the length of the gap vs the length of the magnetic path. That should be enough variables, though the time constant of the DCR of the coil will also fluctuate.

So, as you say, be prepared to throw away many components, until you hit on one that does most of what you want.
