* TABLE OF NEARLY EXACT FREQUENCIES FOR ALL MIDI NOTES (A=440Hz)

* the whole table is really not necessary, but it prevents some

* rounding errors by having it complete, and the cost of 128

* integers is cheaper than the cpu cost of multiple right shifts

* of a table of twelve frequencies, and definately cheaper than

* calculating freq = 13.75 * 2^((n + 4)/12) for each note value,

* which is how this table was created.
