MIDI controller+frame rate issue

I’m using a Korg Nano Kontrol to control various aspects of a patch. Everything is working fine, except when I try to control a transform on the renderer view. When I try this, my frame rate drops to about 5fps. This happens when I connect to any pin on my renderer transform.

Has anyone seen this before?

probably you are putting a spreaded transformation to the renderer (causing your scene to be rendered multiple times…)? make sure to get only a slice of midi into the transform…

when dropping down to 5 fps joreg for sure assumes the true reason.

but it is also recommended to read here about MIDI and VVVV for more info about the buffer length pin on MIDI input nodes.
lowering buffer length may also result in a perceptible decrease of latency (…increase of performance…).
