Hi,
It's hard to say w/o knowing what your method of recording is. Do you see the MIDI notes after you are done recording them? If you do, then it's a playback issue which could attributed to channel routing from the host to the VST instrument. Check that the recorded MIDI data track is routed to the proper channel on the VSTi. If that's set properly, try checking the settings on the VSTi. I've never used MC3, but I think most software handles this type of thing in a fairly similar way. If you can't even see the data during / after recording, it's something else.

Yea you can see the notes afterwards, So it for sure a play back issue. Thanks for the info ima go try to figure it out.
