OK, sorry for not beeing able to explain clearly...
The RTs 2552 and 2553 are finger picked guitars and they sound as they should when hearing them within the Real Track picker.
But once they are used under the demos I mentioned one (2552) sounds ok when the other one (2553) does not sound as a picked guitar but as a guitar playing one held chord per bar and is too loud.
Using the RT 2553 in an other song brings the same result.
Please load the Style _SNGWDUO in your BiaB 2017 and tell me whether it sounds like 2 picked guitars.
And yes, I have the latest patch.
