I recently purchased Studio One 3 and have been having a great time with it. However, I stumbled upon an issue which I hope you would be able to resolve. I have a guitar track loaded in studio one and have added Guitar Rig 5 as an FX on it which I need to control using my MIDI device. I have mapped the pads of my midi device to control the options in Guitar Rig 5, however I am unable to control any effects! I see a MIDI signal sent on my MIDI Device and I also see a MIDI Signal received in Studio One 3. However, the effect in Guitar Rig 5 does not toggle on/off.
