Robert, Welcome to our list. SYSEX messages control the stop changes on Rodgers Organs. Jim Merten, a list member, wrote a nifty program for the PC that would display and write SYSEX into standard midi files. Let's see if he can give us an update on that. We have a number of LDS organists on the list. IT seems as if the LDS church takes their organists seriously, and I know a lot of organists serving other denominations envy that! Every so often we need to define terms, so before I am asked, LDS refers to Latter Day Saints, the Mormons. -- noel jones, aago noeljones@xxxxxxxxxxxxx 423 887-7594 www.frogmusic.com rodgers organ users group, moderator frogmusic press, executive director ! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Find new MIDI music and Guides to Rodgers Organs at www.frogmusic.com To post send messages to: rodgersorgan@xxxxxxxxxxxxx To unsubscribe or change mail delivery (digest, vacation) go to www.frogmusic.com/rodgersmem.html
