1) Fixes bug that caused the HR-16 to send out an incorrect MIDI song position
pointer if any tempo change steps occurred in the song previous to the current song
position.
2) Fixes bug that caused the HR-16 to send out an incorrect MIDI song position
pointer if an empty pattern (8 beats, no drum events) was used in a step of a song
previous to the current song position.
3) Added feature that allows "spot erasing" while in record mode when quantize is off.
This means that the erase button and a drum button can be held down while recording
with quantize off in order to erase all drum events (quantized or not) that occur during
the time that the buttons are held down.
4) Added more steps of shuffle resolution, and changed the percentage display
relationship to the clock. The original shuffle values and new values are shown below:

Despite the displayed percentage being smaller in the new values, there are actually
more shuffle steps than before. The old displayed percentages represented the ratio
between the clock location of the shuffled beat, and the clock location half way
between two un-shuffled beats. The new percentage represents the percentage of the
total time of two occurring beats that the first of a shuffled pair will take. For example,
1/16 notes set to shuffle 8 (shifting every other 16th note 8 clocks late), will result in
the first 16th note getting 32 clocks, and the second 16th note getting 16 clocks (instead
of 24 each when shuffle=0). This results in the first 16th note getting 66.7% of the total
time of both 16th notes (32/48=66.7%), which is equivalent to 16th note triplets. This
percentage representation is more useful than the old percentage.

HR-16 and HR-16/B:
1) Fixed bug which caused single step with swing on to advance in incorrect amounts.
If swing was advanced by 1 while in 16th not quantize, the steps would be 23/96,
48/96, 71/96 instead of 25/96, 48/96. 73/96. This is now fixed.
2) Added copyright notice on power on.
