Thanks for all the replies. I think RealBand is working well on ACIDization but has got that slight glitch for me. After I ACIDize a file using the RB Render command I have already told RB the beats (time signature) and the chord root. So, I expect that when I use the RB command to generate a track section from a loop that the form will already have the the chord root populated. This is not the case. The ACID properties do show the file is actually ACIDdized at this point but is beatmapped as opposed to a loop.
When I generate a track from the loop I now have to populate that chord root AGAIN (In my view a redundant step). But this step would appear to put the chord root into an auxiliary files with the same name as the loop but with the file extensions .bt1 aand .bt6. So I don't think the loop contains any more information since, if I delete the .bt1 file I revert it back to having no chord root information)

If this is how RB works then that is OK because I just have to remember to the initial ACIDize simply sets a property in the WAV but does not include any other information. It is only when I generate a track from the loop that I will have to enter the extra details (but this only happens that first time) when a subsequent track is made from this loop then the details WILL be populated in the form (so a long as bt1 and bt6 are there - maybe that is the reason why the WAVs must be stored in that fixed loop folder).


But here is the thing! If I select a Sony ACIDized loop when I generate a track, ALL the details are populate and there is NO auxialry bt1 and bt6 files. I need to investigate why that is.

With regard to comments about 'loops being broken' and no form coming up in RB 2019 when generating a track from a loop, well I think I'll steer clear up of the upgrade now.

The ability to generate a track or track section from a loop is the most valuable feature I have in RB and would appear to be unique in allowing the chord progression to directly influence the loop. If I don't have that then I am fully reliant on BIAB stles. So I'll stick with 2017.
