The first thing you need to do would be to download the app itself and then on the top corner, about your very left side you should click on the select file and then if it is your first time, you just have to click on the “new” so that you would be able to start creating your very first track.
After selecting new, you should be able to see a bar top on immediately. You should click on that bar and then on it type up the name that you would like to name your track and then when you are able to do so and finished with it, you then click on the create button.
Hit the plus
Then you should hit the plus symbol that you would be able to see on the bottom left corner of the screen you are using so that you can then proceed to make your own song.
After that, you will be taken into a different screen or tab and then be allowed to choose what type of instrument you want to be able to use. You have a lot of options such as an electric guitar or any instrument that the software has and then just use it like a real instrument.
