I am currently using the latest Windows version of SeeMusic (3.9).
The first notes/bar will travel downwards immediately when the rendering/playback starts and I would like to have them delayed, so that the Saber animation continues to run and I can then add some introductory titles on the video while waiting for the first notes/bar to travel downwards.
Previously what I did to resolve this was to add an empty starting bar in the MIDI, but with the current barline feature, that would display an obvious empty bar in the playback, which may not be aesthetically pleasing.
Apologies, I found out there is a MIDI Start Time Buffer parameter under MIDI Settings as of SeeMusic Version 5.1. This solves the issue that I was facing. Thank you.
