1) Fixed bug which caused a wrong amount of silence at the beginning of a pattern if
its length was changed to a shorter value from the top and there was no drum event on
the old or new downbeat. For example, if no events existed on beats 1 and 2, and the
length from top was changed to be shorter by one beat, the amount of silence before the
first event would be wrong.
2) Fixed bug which caused sysex loading to be garbled if any real-time MIDI
information was received during the sysex dump. This seemed to only be a problem
with IBM MPU-401 interfaces.
3) All individual's names have been removed from the software.
