No reason why the proverbial underlying engine should NOT be able to handle this with the recordings that already exist. Frankly, I think this is a programming thing and not a recording thing....



Obviously, you have not done much audio editing Sam. NOI.

Remember, these are audio files, not midi. Ever looked at the minimum and maximum tempos for the Real Tracks? If the RT was recorded at 85 bpm you can slow it to maybe 70 and speed it up to maybe 100, right? And that depends on the instrument, the strumming guitars seem to be more limited as to how far they can be stretched. Think about what that is as a percentage change. Say you have a piano chord and it's a quarter note. You want to hold that chord for the whole bar or 4 notes. What's the percentage change there? To hold it for 2 beats is already a 100% change and we're talking 4 beats. If all you can time stretch an audio file without horrible glitching is at the most 20%, how can this possibly work? What's 20% of a quarter note? A 32nd? So you can stretch it (hold it) a whole extra 32nd note without severe glitching. Whooee, that's useful. There is no way to time stretch a snippet of an audio track several hundred percent at least not yet without a supercomputer and some hot software. Things are getting better and better all the time so never say never but imho we're not there yet with our home pc's.
Now, I have no idea what they're working on back at the ranch concerning this problem, maybe there's a whole different approach I've never heard about or maybe there are coming software improvements regarding audio time stretching. That would be a huge improvement to go from 20% to 300% in one shot. If that's possible, nobody's advertising it right now. You don't know what you don't know but it still seems to me the only way is to record a file of held chords then, like John said maybe all they need to do is to record the longest ones and the program can shorten them up as needed using volume envelopes or something. But, for that to work reread my comments above about what that would entail.
