Hello everyone, indeed I did not specify the problems related to usertracks,

First of all I would like to thank you all for the help you give on the forum, it is awesome.
The problems related to the usertracks, concern the missing functionalities (problem of artefacts, does not take into account the peaches and the maintained agreements the freezing of the usertracks the possibility of using them in the medley as we can do with the realtracks, limiting the 1 half tone transpositions see 1 tone maximum we could create, say, a UT with 6 keys without losing the sound quality if the ut and transposed).
Peter Gannon had announced that they will be working on Usertrack feature updates in January 2016 so maybe all of us biab users deserve an explanation and whether there is a future with usertrack.
Thank you in advance on behalf of all biab users at pgmusic for giving us one or more answers.
I apologize for my English, I am using a translator.
good music to all Balbuena.
