Midi Guitar: how can I filter out the artifact notes?

Hi, I have a Godin Guitar with an Axon 50 interface. Do any of you know of a way to eliminate the artifact notes (ghost notes?) that I get? There must be a way to filter out MIDI notes that aren't as strong. Yes, I can edit them out after I record them but that's very time consuming. I have not had good results with the Axon software that came with the interface.
 
I love my MIDI guitar but haven't had great results so far.
 
Thanks!
 
 

Aah that's the age old question isn't it?
I've used MIDI guitar in the studio since the first guitars came along in the 80s.
Always been a PITA to edit.

These days I pretty much just record it as audio as it just saves me heaps of time. I just loop the section and overdub until I get a goodun'.

I also have an AXON 19" rack unit around here somewhere but use the Roland GR55 module with the Axon pu plugged into a Les Paul standard. I am just back in from Xmas holidays and plugged it in this morning and will definitely need to reset the sensitivity as I am getting lots of random notes.

There may be a Cakewalk CAL routine that eliminates notes based on velocity somewhere on the net. 

Last time I looked the Axon forum was limping along but active... Sadly, Terratec is famous for dumping support of their products and the Axon is no exception. 
I fell in love with this company back when the EWS64XL (with Ed!son and Waldorf synths) had a fanatical fanbase and lots of excellent mods being made for it... then they dropped the ball big time.
The Axon was IMO their last hurrah. As I said, it is in an fx rack here along with a bunch of OB gear that doesn't see much action.

Again I'd recommend sniffing out a CAL routine on google or by checking inside Sonar.
Hope this helps :)

You might try Deglitch. From the Help file: Deglitch dialog The Process Deglitch command opens the Deglitch dialog box. When recording MIDI guitar, even the best players occasionally play unintended notes. The Deglitch feature allows you to filter out many of these unintended notes. There are three filters in the Deglitch dialog: Pitch With the Pitch filter you can set the maximum pitch allowed in the track. If a MIDI event has a higher pitch than the maximum you set, it is removed. Velocity With the Velocity filter you can set a minimum velocity allowed in the track. If a MIDI event has a lower velocity than the one you set, it is removed. Duration With the Duration filter you can set a minimum note duration for the track in either ticks or milliseconds. If a MIDI event has a shorter duration than the one you set, it is removed. *EDIT* Typical Firefox formatting BS.

I asked about this a long time ago and I am also interested. I use the roland GK-3 with the GR-20 to send the midi (i know it's old)

The specific function you want for this used to be called Interpolate in 8.5 & previous.

It's still there in X1 but not under that name - try selecting all your data and going through whatever's on the Edit Menu, I'm sure it's in there somewhere.

A hardware solution [MIDI Solutions Event Processor or Event Processor Plus] can minimize, transform, or eliminate them before they ever reach the DAW.  These are inline MIDI processors that can be programmed to do just about anything.
 
I use the Processor Plus in so many different ways that I can (almost) justify adding a second or third one.  It's hooked up to a MIDI router in my rack, so it's possible to 'insert' the device before or after keyboards, guitar synth, MIDI-capable effects, etc.

Midi does not know harmonic combinations or altered unisons. Any two or three notes sounded-struck in such away as to create a note made of combining frequencies is going to create a ghost note which midi will approximate and notate whatever is the closet in its library. It will not be what you played, what you created with the harmonic recombination of string reverbarations or what midi picked up. It will be a best midi guess because there is no note number for blended-recombined-unison notes in midi. There has to be a certain amount of... "space" between notes for midi to notate them. If they are too close together and blend, you get a ghost note which is not what you wanted. I haven't found a way to make the voice of guitar happen in midi in such a way that the harmonic voice inherent in guitar gets registered in midi. You might not get what you want even after deleting the ghost notes.

A guitar midi interface with a sensor for each string should be able to distinguish pretty good what is basefrequency and since only one note from each string is present.

Electro Harmonix POG2 (Polyphonic Octaver) senses polyphonic material pretty good from audio even. So algorithms develop over time it seems. POG2 is really nice.
