I think that it would be best to add a numeric argument for dot so that the user can easily "double" and "triple" and "quadruple" dot without having to add multiple dot blocks.

The dot block macros would have the value of 1 by default (one dot).

0 would toggle dot off.

Dot can be described as:

for a note value x and a dot value of y

dotted_note = x + (x/2^y)

Negative values

At first, -1 sounded illogical to me -- however, it seems to make a kind of "inverse dot", which is kind of interesting.
