So, and if it is possible, what friendly softwares could you advise us for this type of workflow (always on PC/Windows)? Thank you again for your attention and your professional lighting.
The more control you have over the music, the more complex everything becomes. Many aspiring music producers become lost or give up due to the complexity of volume and location/spacialization of instruments otherwise known simply as "Mixing."
If you're really looking for something to keep it simple you want to minimize how much mixing you will have to do, and for that I would suggest a program like Fruity Loops Studio which unlike the name suggests, isn't just loops but professional and full production software, especially for beginners.
Fruity loops contains many visual feedback plugins which help to SEE the changes you are making to each instrument rather than just looking at a bunch of knobs and sliders.
Fruity Loops also contains many demo files and tutorial projects you can open up and examine to learn how everything works.
Another reason I recommend it is because the workflow is based on creating repeating loops and mixing them together rather than having to put everything manually onto a linear time frame. This makes the music a bit more intuitive and fun to make.
I grew up on Fruity Loops and although it does not give me control over my mixing as much as I would like, I still recommend it today.
Personally I use Ableton, but ableton is not as beginner friendly and frankly it's starting instrument library is pathetic.
Fruity Loops is better for an out of the box experience because it includes many powerful and unique synthesizers to get you started whereas Ableton and many other professional DAWs (Digital Audio Workstations) pretty much expect you to install your own synthesizers otherwise known as VSTi's.
VSTi instruments are compatable with most DAWs so if you download some and use them in Fruity Loops then eventually switch to another DAW, you can carry over your synths and still use them so it won't be a completely foreign experience.
My general advice to all new music producers would be to keep the volume down and turn your speakers up until you get a lot of practice. Then and only then would I recommend experimenting with raising the volume or using tools on your instruments to make them louder in the software itself.
