I bet it is by calculating the automation. Think about it as a math integral. From certain point to certain point, it has a constant value. From the other point to other, it has certain value. It would be something like this I think.

int milliseconds = 0;
for(int x = 0;x < bars;x++)
{
for(int y = 0;y < automationpoints;y++)
{
milliseconds += point2 - point1 * tempo; // Assuming it is a bar
}
}

You then convert milliseconds to seconds and minutes.This is recalculated each time song changes length.

Subject: [LMMS-devel] Feature request: timecoded timeline

Hey - I often find it really hard to find a specific point in my track- because the timeline displays only bar numbers.

If the timeline displayed also timecode (simple) MM:SS it would be big help in work.

I see this is tricky, for the tempo might be automated, I don't know if this would be a time-consuming process to calculate a time-map. It might require streching some clips to keep the playhead speed constant (Ardour style), or just create a "timestamp calculation" threadm that would be launched to update a timecode  array, when thempo (or it's automation) changes.

Anyone knows how to code this? Or maybe it's already done?

Bless,
unfa
