R3.2.4 Win10 x64
I have found a problem in the visual selection of the device using:
renoise.song().selected_sample_device_index (visual centralized not exist!)
When changing this value from the tool, the effects device panel should automatically mark and center the selected device. Renoise marks it correctly, but does not center it.
In the track’s DSP devices panel, it does work correctly with:
renoise.song().selected_track_device_index (visual centralized ok)
Edit: It has not yet been added in R3.3.0.
