In plugdata v0.9.2 hosted on REAPER v7.48 running on both Windows 10 and 11, I can't set the plugin's latency under Settings...->Latency (samples). When I enter the number of samples and close the dialog box, it immediately reverts to 0 and REAPER reports a plugin delay compensation amount of 64 samples which is what it reports when plugdata is first loaded. I fell back to plugdata v0.8.3 on my Win10 machine and was again able to set the latency, so there's my workaround.

Surprisingly, if I copy that same REAPER project hosting plugdata v0.8.3 over to the Win11 machine that has plugdata v0.9.2, it retains the latency I set on the Win10 machine, but as soon as I try to edit it, it reverts to 0.

Anyone else seeing this issue?

I'd also love to know if there is a way of setting the plugdata latency setting within Pd. My patch has a look-ahead detector, and when I change the look-ahead amount, the latency has to change accordingly.
