I'm on the latest releases of both KK and Kontakt and I've uncovered what seems to be an anomaly with Action Strings 2 in the way it gets converted from MIDI to a .WAV in Ableton 11 on Windows 10. To be honest I don't know if it's just Ableton or if it's in Action Strings.
Within the project I can mix an Action Strings track perfectly balanced with the other MIDI tracks. However, when the tracks are converted by Freeze and Flatten into individual WAV files, all the other tracks retain their same volume they have within the project. But the Action Strings track volume drops to almost nothing and the visual audio representation in the Ableton audio track represents it has clearly dropped in volume during the conversion. The only way this doesn't happen is when I convert the individual track to audio directly either as a WAV or MPG. However, when I convert all the tracks in bulk through the same process, the output of the Action Strings drops as it does in all other cases in comparison to the other tracks.
I'd just like to find out if anyone else is experiencing the same thing with Action Strings 2 in other DAWs which would indicate there's a problem within Action Strings. I find it hard to believe it's a problem in Ableton as I've been doing these types of conversions on a regular weekly basis for several years across tons of various NI and non NI plugins and this is the first time I've seen it on any plugin.
