Thank you to everyone for your input on my question that started the thread. It appears we may have a hung jury on the solution, so I am going to try and experiment with it by Saturday, 04-19-14. As I understand the responses -

1. We have Jim’s instructions:
• Go to Preferences>Display, and in the lower right section where you can choose what the Spacebar key does, choose "Play from start." (This step may not actually be required but I find it to be very convenient.)
• Here's the important part: also in Preferences>Display, put a check mark in the box labeled "Pause Play Until MIDI or Key received."


2. Then we have jcland’s observation that:
• “As it stands now, every time you use the space bar, BIAB has to reload the entire song.”


3. Jim assures us that hitting the spacebar a second time, with BIAB set up per his instructions, will not cause the file to reload and will start playing immediately with only a split second pause.


4. Then Dan added that the tracks need to be ‘frozen’
• “Go to your preferences to set it to play from beginning with space bar, and be sure you have the tracks frozen otherwise the default appears to be a regen.”


5. Jim then remarks:
• “…….then it will begin playing from the beginning almost immediately (only a split-second of delay) without regenerating. I don't freeze any tracks and this is how it works for me.”


6. Finally, Dan summarizes:
• “Indeed in this case we are both correct! It appears the space bar, when configured in preferences, will play from start, but it does this with a regenerate. Now you can either freeze the track to stop this action OR you can tell it to wait for a midi signal, which can be another space bar.”


So I’ve got some work/experimenting cut out for me. I’m hoping that Jim is correct and that I will be able to set up BIAB per his instructions to
• Load when hitting the spacebar and then wait until I -
• Hit the spacebar again and begin playing from the beginning without a regenerate


One point I am wondering about is the versions of BIAB that everyone is using. I am using 2014. Perhaps there are different results for users in this thread because of the versions that are being used which all may not be the same and possibly have differences in the use of these parameters……

Thanks again for everyone's input. You have all been a tremendous help for this Newbie
