Requesting "instant doubles" function

[Sean M. Pappalardo]

Requesting an "instant doubles" function which is a GUI button that basically copies the track, current pitch, position, cue points, loops, etc. from the current deck to another one. This would also allow for (limited) single-deck vinyl control since once you have a song going, you can instant-double it to another non-VC deck then use the VC-deck to cue up the next.

Very important missing feature. Please prioritize.

[Renedjenkins (renedjenkins)]

Please add. Very needed.

We just need a contributor who has interest and time to implement it. It is not hard.

I am interested in mixxx development and thought this might be a good place to start. Could I get a quick instruction on where to start? I have a few years of experience in Java/Kotlin but not in any C dialect.

[Daniel Schürmann (daschuer)]

Cool, thank you very much.
In general this is a good place to start:

Here, it is probably the best to decide how to control the feature from GUI and controller.
Do you have a good idea?

C++ is quite different from Java regarding the underlying technology, but it should be readable for you. I am happy to help you for the rest.

Implementation in progress https://github.com/mixxxdj/mixxx/pull/1892.

Added to the control docs on the wiki.
