Thank you for the detailed info Roland! I've been working on various stability improvements as suggested by you in other posts but you've made some excellent points for me to consider here. The idea of tracking tempo changes from the DAW to the plugin would require the user to play through the entire song for the plugin to record every tempo change. Instead, I would recommend that you use the bar settings dialog in the plugin to add tempo changes while you are building your song, and then import a tempo map into your DAW using the [C7] button above the chord sheet. If you do this then the plugin and DAW should be in perfect sync. I really appreciate all your great feedback!
