"The problem with BAIB is the tap tempo is terrible compared to other tools out there. Try in the middle of song to adjust the tempo via tap. Then try it with Midi Maestro - it's perfect. If I only use midi tracks with RB - then I can exactly follow tempo."

Here is lies again the problem. You and others here (myself included at times) keep trying to compare BiaB and RB to other systems and wonder why it can't do something the other program can. Try to get midi maestro to do anything else that BiaB can do. It is easy to point out one thing BiaB does not do that some other program can. You can ask for one program to do everything, it is not practical or even reasonable. So many want what Mac calls the swiss army knife of recording. A Program that combines all the features of every other program out there, would be bloated and clumsy.

Let's look at the other issue, you want RB to adjust the RealTracks like BiaB does. First off that is a feature of BiaB due to it's auto accompaniment structure not a feature of a Sequencer. If other sequencers on the market could take a Realtrack and on the fly tempo adjust it, then I would maybe find RB deficient. But wait that's right other Sequencers can't even play/generate/process RealTracks, let alone adjust them. Some programs, Sonar, Acid can take groove clips and acidized loops and do crazy things with them, but those are nothing like RTs.

I do think understand what you want here, and if you want put it in the wish list. I doubt it is possible anytime soon. Maybe Elastique is the beginning of these things, we have all seen what Melodyne can do with audio. It never hurts to ask for stuff, but i guess the reason i am sensitive about these things is that i have seen what over development does to a great software. All one has to do is go to either cubase, or Sonar forums and read the countless bugs and problems they have with each successive release it doesn't get better it gets worse. Sure those programs settle down after a while, but there are bug fixes that are three and four releases old and hasve never been sorted out. Mostly due to new features added that over shadow the old, and cause countless new issues to fix. I hat to think of PG becoming that way as well.
