Default Using export_buffer_to_project() hangs and crashes REAPER

Using export_buffer_to_project() in a @slider block in a JSFX hangs and crashes REAPER if:
* The project is playing back
* The JSFX is on the monitoring FX chain

It is still possible to trigger the crash while the JSFX plugin is on tracks instead, but it happens less frequently.


REAPER version: 6.42
OS: Windows 10 64bit

Perhaps using export_buffer_to_project() in the @slider block is not a good idea in the first place, but as far as I can tell this is the only place where we can use this function without showing the JSFX plugins gfx window.

Hmm yeah don’t do that, it’s nit allowed (we’ll make that enforced).

I'll look at adding an option to have @gfx run even when the window is closed (for idle processing), that could be useful.

Today's dev build adds support for options:gfx_idle or options:gfx_idle_only and a gfx_is_idle variable

Would it be possible to add export_buffer_to_project to the documentation? It seems very useful. I'm not exactly sure what planar_pitch is supposed to do.

Ah yeah, it's about that time.

For multichannel exports: planar_pitch should be 0 if interleaved, otherwise it is the distance in memory between channels.

As an example, suppose nch=2, your left channel is at offset 1, your right channel at offset 10000001, and you're writing 32768 samples, you'd call:

export_buffer_to_project(1,32768, 2, srate,trackidx,flags=0, 10000001-1 /* or right_channel-left_channel */);

Thanks, that makes sense!
