This problem has arisen recently. When accessing any plugin, whether NI or not, the audio is distorted. It does not matter whether I use a plugin standalone or in a DAW (I use Logic Pro). I note that in Dorico, which has a MIDI indicator light in the lower right of the window, the light is always on if the keyboard is on. MIDI information is going into the program (I can hear it playing the patch), but no note input. I thought this was a Dorico issue, but it was suggested that I have some sort of MIDI feedback loop.
None of this occurs when I unplug the NI keyboard and plug in another keyboard. Is there some setting on the NI keyboard that I have inadvertantly made? Any thoughts would be welcome.
