I have posted below an example patch to demonstrate some of the behaviors I find confusing.

Part of the behavior in question has to do with how the patch loads with a loadbang, so if you don’t notice the behavior I’m talking about, then try saving the patch and reloading it.

Questions:
1. In tests one and two, upon loading the patch, there is a 5×5 grid in the output windows, but when I retrigger the spatial map that goes into the right inlet of repos by clicking the “Click Me” trigger (which should be sending in the exact same matrix as was originally sent with a loadbang), then the outputs of tests one and three suddenly become interpolated! I still cannot figure out why this happens upon trigger but not upon loadbang. *Nothing* should have changed between the loadbang triggering the spatial map matrix and manually triggering the spatial map matrix.

2. In a separate phenomenon that I also can’t figure out, test three, the matrix going into the left inlet of repos is only 5×5, and the output in the window is interpolated, but the pwindow output, which has been fed through a jit.matrix object, is not, even though I turned interpolation on!

I feel like I must be missing something obvious here, but for the life of me, I can’t see what that is.

Thanks in advance!
