I am on a constant hunt for usable Celtic RealTracks. Often, the combination of instruments is inappropriate for that type of music.

And when referring to a jig, the specific type of jig should be included. In the Celtic RealTracks I never see certain instruments that are commonly seen in Irish music groups.

The Hornpipe RealTrack has two instruments, one of which is a acoustic bass. Has anyone ever a Irish group with consisting of just these 2 instruments ? The other other instrument might be a guitar. I would prefer hearing tenor banjos, accordions, a pennywhistle or flute, or the bouzouki.

Finally, I hate seeing electric guitars included in music that never has electric guitars. None of the Irish RealTracks seem to have a fiddle. The fiddle is usually one of the main instruments.
Not having a fiddle would be like not having a piano in a jazz RealTrack.

I have used BIAB for decades and enjoy using it. But for some types of music, I spend more time looking for rhythm RealTracks than I do using BIAB.
