Prior to buying the MKIi49 I was using a Prophet 6 to control plugins in Logic. This never occurred with the Prophet but with the MKII this problem has surfaced. I can’t imagine the technology that would cause this but this is the case since I switched to the MK. Nothing else has changed, only the controller is different. In fact when I pull up an old project created with the Prophet 6 as the controller I can’t play any of the plugins with the MK. Furthermore the on the templates I created using the Prophet 6 the same thing occurs. A controller should only send and receive MIDI data, it shouldn’t affect anything else in the DAW but in this case it does. I hope this explains my problem a little better. I am at a loss. I could live without the NI plugins, lord knows the Arturia V collection has enough plugins but the piano plugins with NI are far superior to those in the V collection.
