It should work however, just like all the other big samplers like Sampletank, Halion etc it doesn't work well. The reason is this is not your basic GM soundset like the VSC or Forte. These samplers will not simply load and play with different Biab songs. You have to open up the Aria player and manually set up each channel for each individual Biab song. You can get Biab sounding great this way but it's a pia to have to do that for every song. Also, there's a delay involved with the program loading a sample if there's a program change being generated by Biab and this can happen often. Since Biab is playing in real time, if there's a program change like switching from a nylon guitar to an electric in the middle of the song, there's no time to load that new sample so Biab will lock up. That's not Biab's fault, it's because of the sample loading times. A GM soundset only has a few different versions of sounds like strings, two acoustic pianos etc while GPO and other samplers have gobs of them. They can certainly sound killer but it takes time for you to decide which patch you want for a given song. This is why the VSC and other basic GM players work so well but only sound decent, not great. There's a limited number of samples and they have to be small enough that they can all load into RAM so they're instantly accessible by Biab.
If you're into creating finished masterpieces of your songs, going in track by track and tweaking everything to make it perfect then certainly this could be the way to go. Oth, if you like going through your directory of Biab songs and running through a bunch of them in one sitting or playing a live gig, this is no good at all.
