I just read about the latest BIAB upgrade today. Yes, I'm sure I'll upgrade before July passes. However, it's interesting to me that no vocal real tracks have appeared as yet. Is that because of less interest in such real tracks? Or, are they difficult to create compared to guitars, keyboards, etc..? Or, maybe there are other reasons. Maybe some this December? Someone mentioned the Yamaha Tyros 4 and its vocal components. The styles in the T4 are impressive to me, since the vocal parts add so much to a rhythm track.
