However, even if I fix the bug which is preventing the changes to be reflected
on the sequencer, it means that each tempo change is remapping the whole
composition. It's acceptable if the tempo is changed through a dialog asking
confirmation for instance, it's not if it's done by moving a slider and the
user expects instantaneous feedback.
I was wondering if it would work for the sequencer to recompute the events
play time by dividing by the "mapped" tempo (the tempo which was used to
compute the event's time) and multiplying by the user requested tempo (the
tempo currently set by the user) ?
