Filter short incoming midi notes
Any midi plugin that deletes notes that are shorter x ms? I know that would also delay the midi output with x ms but that would still be acceptable for me. removing notes after recording is not an option for live use.
If I understand your question correcty, you want to remove short notes in real time, not after clip gets recorded, which woud let one scan fast through the clip and delete short notes.
This makes no sense for real time input of any kind, and so for any kind of live use in case you want to hear and record only longer notes.
you know how long one note is ony after it gets released,
but if one uses clocker, than you know also before if it is going to be longer then set time, but output delay would be as long as set time.
- you receive note on, start clocker, if > than set time, play it and wait for note off and then delay it for set time.
that keeps note length intact.
if note release comes in before set time elpses, don't output the note.
But who would play in real time under such conditions ?

Maybe you want to hear all input, but only record longer notes ?
could work, because you would have full loop length to scan and delete recorded short notes.
Thanks for your reply. am playing Fender guitar on Behringer PP1. Guitar sound goes thru immediately. No delay. The midi from PP1 has the ghost notes. They are only a few ms long. The other notes can be delayed a few ms because they trigger ambient synth with slow attack, so this still makes sense to have a delay for this live setup
that gadget is monophonic, or ?
I mean it works acceptable only if you have no overlapping notes ?
In that case you will be way better to use max pitch tracker instead.
to remove that "ghost" notes ...
it depends on what they are.
repetition of current detected note, or something else,
like wrong pitch detected ?
it would be very helpfull to see both audio and midi inputs recorded to analyse them.
this is one option, it should work if ghost notes are not
same as valid sustaining detected note.
if ghost notes are retriggered duplicates of current note,
one could try makenote
Hi SOURCE AUDIO. Thank you for your feedback. The PP1 is monophonic. In following example I play notes on the same string. The resulting midi from the PP1 is also monophonic. The very short notes are the ghost notes. I will check you Max patch more in detail and I will convert it to M4L.

Please note that in this example I did less fine tuning of the input gain and the gate of the PP1, which gives a lot more ghost notes than when it is perfectly finetuned. I did that on purpose to better show which types of ghost notes sometimes appear.
one could say that behringer has problems with pick portion.
it false triggers either same note or wrong detected one,
probably when it tries to quantise freq to note.
I would really prefer to have both audio and midi recording ,
to really analyse the problem and offer solution.
Can you do that ?
Record guitar and midi in 2 tracks in arrangement mode
and post zipped ableton set if you have no other means to record that 2 sources in sync.
You can use https://files.fm/ for example to upload the zip file.

I am quite sure that you can get better results using
max pitch detector, but it would need to have audio input and midi output enabled.
P.S.
it woul be helpfull to have all 6 strings recorded.
I use hex guitar 2 midi since it existed, had many different systems
and know about the problematic.
