Alleluia by Samuel Hazo has two key changes, at m. 77, and at m. 94. Neither one is indicated on the 1st Alto and 2nd Alto parts inside MakeMusicCloud. They do not occur when in plain viewing mode, or in playback. There are some places in some of the jazz arrangements where keys and/or D.S.'s or D.C.'s disappear during playback. I could have a full-time job just fixing the oddities that have been mis-entered. Anyone else hit this in other pieces?
