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. HR-16/HR16B Service Manual 1.00 22
