I am using loops in Kontakt (in this case Heavyocity’s Scoring Guitars). The midi has one held note for 2 bars, which triggers a guitar phrase. I then duplicated the 2 bars into a 4 bar phrase, 2 x the 2 bar loop. In playback at the end of the 2 bar phrase, it does not seem to stop, and now I have 2 of the same loop playing on top of each other, with some phasing.
It works fine if I slightly shorten the length of the first note. When the 2 same notes come straight after each other with no break, it appears like there is no Midi Note Off for the first note, and it continues playing …?
I did a bit of testing. Other libraries/soft synth arps etc are working OK.
Within this one library itself, its only certain sounds that have the issue - some others don’t (if you have Scoring Guitars, its the Pulse menues that are giving me issues).
I don’t have that library, unfortunately. Are the involved Kontakt presets heavily scripted? (if so, it is very difficult for us humble users to troubleshoot/correct a problematic preset).
