Same questions for me... I suppose that the developers are still working on it, and that it will pop up some day in an astonishing way ? But I will be glad to hear it, and if possible to have some idea if this will be in one week, one month or more.

Any recent word on the status/timeline for PiP?

If you wish to use it (in experimental unsupported form) in 3.1x, you can set pip_en=1 in the [reaper] section of reaper.ini. -Justin

Thanks, Justin. Can I ask if PiP is still in development? Are you interested in problem/bug reports on it, or is it more a hands-off "use at your own risk" thing at this point? I ask cos I'd like to use it but am having some odd issues... I just enabled it in 3.13rc1. Lots of potential in PiP.

Tallisman, were you able to get it working in 3.13rc1? When I do it, I'm able to insert a project, but when I play it, I get short burts of playback, like every few seconds, during which the transport time advances about 50 ticks, then sits unchanged until the next burst. Yet.... when I use the record live output command to record these bursts of playback, it sounds like normal playback. EDIT: make that, it sounds MORE like normal playback. Strange. Like I said above, I once got pip working, playing an inserted project the same as playing the source. But it's never worked a second time. Is this just me?

can't find pip_en= in my reaper.ini humm

You can just add it yourself at the top of the [reaper] section, which was the first section in my ini.

Love having the option! Thanks Justin. :)

I'm very interested in this feature, I didn't realise it had seen the light of day

Still like to know if the devs are interested in PiP bug reports?
