When using S1 to score for film, you'd normally want the editor view to follow a Frame-based grid for cue mapping. So let's say a theme starts at a particular frame, and has a particular tempo. You'd create an Instrument part that will hold the musical information. However the issue here is, the underlying beat-grid still applies, and chances are that the start of that Instrument part is located somewhere between 2 beats of the main editor grid.
Is there any way in S1 to make a beat-based grid for that instrument part, separate from the main editor grid and that starts right at the beginning of the event and is tied to the later, so that if you nudge the event a few frames the boundary of that event is still bang on Bar1-beat1?
If not, then this should be a must-wanted feature for the ability to use S1 for film scoring.
