@Sing4me88 I know I have said this before but I think you have truly “outgrown” your current setup and if you can raise the cash I think an investment in a proper DAW would take you to the next level as what you are describing is just a “drag and drop” in Studio One Professional, which would analyse the loop, tell you the chords AND you can set other loops to follow these chord changes - it would take less than a minute to do
Studio One is much more than a loop manipulator so there may be better (and cheaper) options that focus on loops
Although, I would then fear you would quickly outgrow one of these packages and want to programme your own basslines, lead lines etc. - so will then be looking for something with these features
I can’t rate / recommend Studio One enough and if you want something to grow in to
The full package is £344.40 or they do a continual £13.46 a month for the Presonus Sphere (which gives a load more goodies) - but if you stop paying you loose access so I prefer the “buy outright” option
There are cheaper options so check out the usual candidates (Cubase, protools etc.) as well as Cakewalk Sonar by Bandlab, which I also highly rate and I believe it is free now - although I am not sure if it has the “chord track” thing you are after
If you will stay “loop based” I would definitely check out Acid Pro, Ableton, Fruity Loops
