The Song files included in this particular archive were originally developed by PolySoft, Portland OR. They are intended to be played on Roland MT-32s or 100% workalikes "as-is". They sound mostly GREAT on mine! :-) The sample batch (shell) proc included will play the converted SMF files from PolySoft in the correct manner. The docs are "in" this batch file. It discusses SysEx data also. -- Paul Seniura. p.s. you need the MFPlay command found elsewhere in this database.
