When I record and press a key on my keyboard, two notes appear in Hookpad.
Yes I know. I already fixed that. I think the update just hasn’t been pushed yet.
In the meantime, one workaround is to enable the Midi controller and then reload the website. The problem is that right now, each time you open the midi preferences window, a new observer which is listening to for midi notes is being added. So as long as you don’t open the midi preferences window, you should be fine.
