Again, thanks all for all your answers, you are all very nice with the newb that I am smile I'm going to respond collectively.

My DD is 7200rpm so should be good there. But unfortunately it is no a ssd.. Question : if I get a usb SSD external drive connected to my pc and put all the RTs on that ssd drive, will it be faster even if it is an external one ?

Thanks for suggesting to check what's running in the background, I disabled some stuff automatically running at startup and got rid of 1 of my 2 antivirus.

Yes the AMD is not the best I presume (tbh this is my wife's computer that she's not using anymore so it is handy for me to use it instead of buying a i7 based new one, but it comes at a price : the speed).

There are a couple of comments here implyging that I want everything delivered immediately. I never said that. What is annoying is to have to wait 30 to 40 secs (I checked my chrono) for each single change. If you have a couple that's fine, but if you test RTs and arrangements and end with many changes it becomes difficult not to get annoyed. To all those who only have to wait 5 to 10 secs I'm sure you will understand.

Now clearly it appears that the issue is more CPU based.

Here is the CPU benchmark result (dunno if the GPU test is useful I only did the CPU one) : https://browser.geekbench.com/v4/cpu/15085526

I will definitely double click on the bar (thanks for the tip)

So I tried the "freezing tracks" tip and compare the waiting time. Each time I opened a song, made a change and generated it
- without freezing all the tracks : 25-27 seconds
- when freezing all the tracks : 10,8 secs

Now the song has been generated but I stop it before it starts and want to start on another bar :
- without freezing : 9,3 seconds inspite of the song having been generated already (for the 1st time I try randomly, after that it's ok)
-when freezing all the tracks : 1,4 sec

So I guess that this proves that the CPU is the guilty one ?
Now I wonder if I can upgrade the cpu on my motherboard since this is a HP 2 in 1. But oh well this is not a computer forums so I won't bother you with that, I will figure out.

That being said I don't see the point of freezing (please don't scream smile ). I mean if I freeze all tracks, I can't add any more chords (they won't play) or any new RT (here it's even worse BIAB bugs but I'll keep that for another post). So I presume that freezing tracks is recommended when I "just" want to avoid waiting for a song to play ? Sorry for the noob question.
