Summary: harmon234 issue

Initial Comment:
perhaps this is a bug:
p4 doesn't always seem to kick in using the harmon234 opcode.
It has an effect typing in the p4 value directly but when using the score below, the result is okay when the p4 change is from a higher to a lower value, while in the next section where values of p4 change from low to high, the result stays frozen at the first p4, ie. 5

Message:
I have committed a patch to git.  I have left the bug open for the present
as I suspect a more efficient fix may be possible.
  Not tested totally yet either

Message:
Reading the code it does seem that many initialisations are not done if
thre was an earlier structure and lower goes up.  Will look more closely
later
