add playposition_samples

[ronso0]

Feature Description

Just an idea to simplify position comparison in scripts, which currently requires calculating the sample position with playposition * playposition_samples
Would be an equivalent to sample positions like loop_end_position and others.

i would like to work on this issue.

[ronso0]

Just do it.
(tasks are not 'assigned', whoever likes to work on this or that simply does it)

[yatigautam]

Thankyou.
I would be grateful for your advice on how to approach the issue effectively.

"playposition" is a relative control (0.0 = track start, 1.0 = track end).
Other controls, "loop_end_position" is just an example, are absolute controls (value is track samples), so find out what control type these are and how they are set.
Find out where "playposition" is set, add a new absolute control, probably use toEngineSamplePos() to get the value from the original (internal) control.
I think all this is happening in EngineBuffer.

[yatigautam]

How can I ensure that the new absolute control behaves correctly across different playback scenarios, such as when the track is being looped or when there are tempo changes?

[daschuer]

Since "playposition" is known good, you may find all places where it is written and replace it with a wrapper to write this along with the new "playposition_samples"

What do we need that new control for? You can already just multiply the track_samples and playposition COs. Do you need this calculation often enough that this additional CO is needed?

I'd rather not add more sample-based COs when we plan to switch to frame-based COs for a long time but also need the sample-based ones for backwards-compatibility.

If this is just about scripts, we could also add a JS helper method instead.

[ronso0]

Agreed, let's go with the script helper.
