Does anyone have advice on preventing the triggering of ghost notes an octave away from the note you are playing?
It’s particularly bad when I play an open low E, A or D then play on the upper strings. A low E still vibrating will constantly produce more low E midi notes even when I’m nowhere near touching it.
It’s not confined to open strings though; fretted notes also produce ghosts an octave away.
I’ve switched guitar, changed pickup selection, played with gates and filters - nothing helps. Is there a “fundamental filter”?
I think I understand what you are saying, and its something I’m aware of:
If you have low open strings hanging, and play high notes (octaves) the low note will turn off/on sometimes. It’s difficult because when you pluck a loud high E over a weak low E already hanging there, there is a time interval where the low E is really not audible (for MG or humans) and MG turn it off. But then when the high E becomes weaker, you can just hear the low E again and MG turn it on. It’s abrupt because it’s MIDI, but in this sense it actually mimic what you hear.
It’s possible we can do something about it. MG3 already does better than MG2 in this regard, and of course it’s not an issue with MG3HEX.
Not quite my experience. I hold down an E chord and hit low E, then B, then mid E and as soon as I hit the mid E, the low E triggers again. It doesn’t wait for the mid E to fade.
Does that what you just described also happen when you play e.g. a barre F chord, or just when open strings are involved?
It might be worth to try to muffle the open strings slightly.
It does happen with fretted notes too; I’ve triggered a G# an octave above the one I was playing on the G string, first fret. It’s sometimes like playing a 12 -string guitar intermittently.
I have discovered that it happens less if I pick nearer the bridge, but that’s not something I can naturally do.
Are the velocities of the “ghost notes” and mistriggers significantly lower as from the desired notes? If so they could maybe be filtered out on the MIDI track inside the DAW. Not sure where you put your test gates and filters mentioned in the first post. I’m using MG3Hex and have only very little unwanted events on the MIDI track.
Yes, they’re about half the velocity and I can take them out individually but they couldn’t be deleted via an automated process - too random for that.
I’m going to experiment by creating a “perfect” audio file from the instrument via midi keyboard, then feeding that through MG3 and see what it makes of it. Should be interesting.
I’ve found that I have a lot less of those ghost notes if I apply a cutoff filter above 4-5kHz before passing the signal to MG3. I imagine that by cutting off the harmonics, this may weaken the contribution of those higher notes.
