The curve won't have a continuous derivative, which may sound weird if the 
curve is played slow enough. If ever your solution is not sufficient, it 
might be better to try to come up with the integral of some continuous 
function, but it may be a bit hard to make it align with the desired 

for wide vibratos, it's also important to ask yourself which scale you 
want to work in: linear vs logarithmic sound different for any 
sufficiently wide vibrato.
