The app itself would help you to record your own track with a microphone so it would be just like you have your very own tempo that you can record with a high-quality recorder. This would be truly something that is important especially if you want to make it sound like it is a professional sounding track mix.
The electric guitar of the app is a custom-made guitar that you can even adjust the settings of. It is something that would be really useful for you in the long run and would totally be something to try about. It is something that can be used for different things like making your own song or a remix.
Just like a proper mixer, you will be able to make a lot of different sound by pressing different buttons as well as keys on your keyboard. The app has been especially made to tailor the requirements to suit and help your production of music, after all so you should have expected that all in all.
By pressing the i button, you will be able to get all those provisions right in the left side on your bottom screen. You can also sort things out on the keyboard provided by the garageband for PC app which will be an on-screen type of keyboard.
