I do a lot of songs with several tempo changes. I'll select a tempo for the song overall in the "Song: Title/Key/Tempo/Embellishments" menu's Main Settings box, perhaps 100. Then maybe at bar 32, I'll change the tempo via a bar setting, perhaps to 120. I might have a couple more tempo changes later on in the song, also via bar settings. Unfortunately, the setting I entered in the Main Settings box doesn't always stay at my original 100 when I generate and play the song again. In such cases, it's as though it forgets what I entered, and decides to adopt one of my bar settings, maybe 120, instead. I haven't changed anything in the main settings box; I've only entered tempo changes at specific bars later in the song. I should mention that often I'm using several different styles in a song, also via bar settings. The situation is quite frustrating, since I never know when it's going to happen, but it happens often - in half an hour of tweaking a song, I might have to go back to the main settings box and re-enter the tempo I want (and haven't changed) half a dozen times. Anybody else having this issue? I'm using BIAB Mac Version 2013 Build 74.
