I'm using Amplesound's AGM, and it apparently produces RAW MIDI output of whatever MIDI events are put into it. The MIDI data coming out of the VST is being recorded on the same track I'm intentionally recording onto (which means that every event is doubled), and I've even had times where the MIDI data from the module is being received by Addictive Drums.
 
This is happening even though I've not assigned AGM as an input to anything. Does anyone know of a way I can stop SONAR X3 from reading those events?
 
Thanks

I don't have any of their VSTs, but saw on another forum that they just released an update of all of their plugins. 

X3 is insisting on using the output from Amplesound's modules on any track I'm recording. Seems odd to me that SONAR is using MIDI events as an input when I've not asked it to. This didn't happen in X2.

Read this thread. It has information regarding the issue you are running into.

When inserting the synths make sure the "Enable MIDI Output" is off in the "Insert Soft Synth Options" dialog . I believe this option has changed from X2 to X3 to default to on. For the synths already inserted, right-click on the synth rack row displays a menu with the "Enable MIDI Output" on it.

Yes! This fixed it. I'd never even had to notice that option before. I'm back at work. Thanks so much for your help!
