Guitar Rig 6 Plugin two versions? FX or MFX

Hej there

Neither the official PDF nor the web could answer so far. When loading GR6 in Logic you can choose either a "FX" or "MFX" version (other NI plugins are also named MFX, none however FX).

Loading both doesn't seem to make a difference, so what are those?

    What DAW and OS… there is a possibility that they are two different plugin versions. Load each one and check the version numbers of each. They may have changed the plugin descriptor of the newer version. If that is the case, you want to remove the older version from the scan path…it also may be that one is a 32bit plugin and one is a 64bit if your DAW supports 32 bit!

    I think one supports MIDI. Looks like this may be a specific thing for Logic?

    Thank you toddkc.

    If this is true, it’s awkward that nothing of this has been mentioned in the numerous manuals of GR, if this exited at least sind version 2!

    FX is some midi automation, MFX is even more midi?

    Anyways, I think this solves the question for now. And NI: pls mention it in the manuals for the love of confusion solving. :)

    I think typically the MFX versions are capable of responding to MIDI Notes and Controllers. The FX version only responds to Controllers. However, I just stumbled across your question because it dawned on me that I am unaware of any Guitar Rig 6 Presets that respond to MIDI Notes. I will be exploring this further. If I discover any GR6 functions that respond to MIDI Notes I will add an additional post.

    I think you're on the right track here with Midi being the "M" in "MFX". Using GR6 as an AU in Ableton, I could not send midi patch change messages to the FX version, but I could to the MFX.
