I don't know if this is even easily doable.
But if so could somebody describe in general terms what functionality is missing in the cut-down version of Garageband that runs on iPhone/iPad versus the full version that runs on a Mac ?
I just got some books on Garageband (I think they're geared to the Mac version) and wanted to see if it was worth learning it for mobile sketching purposes.
And I was wondering before wasting time with the books how much of the stuff covered in them would simply not be applicable to the limited version that works on the iPhone/iPad. It might be very frustrating if I read about some function in the book only to find its been cut out of the iPhone/iPad. (I do not own a Mac). Exactly how much difference is there and how crippled is the cut-down version ?
Thanks,
Bob

GarageBand for Mac is an audio editing application that has been vetted by Apple. It basically turns your desktop into a music creation studio. It lets you perform virtual recording sessions from anywhere and add effects to your sound content. There is a huge sound library included with the application as well.
Approximately 40 lessons are built into GarageBand for macOS, which teaches various ways to play different music types. Some of which include pop, blues, rock and classical.
Your practice sessions are tracked in real-time by the Garage Band app. Afterward, statistics on your level of accuracy will be provided to you.
If you are interested in Artist Lessons, you can practice playing famous songs and receive advice from their creators at the same time. However, you must meet the extra requirements to be entitled to these lessons.
GarageBand is perfect for anyone who creates and performs their own songs. The application lets you utilize a virtual session drummer or the instrument sounds found in the library.
If you have an iPad, you can use it to play any instrument that you want. The Logic Remote feature lets you connect your device to your Mac computer. All you need is an active Wi-Fi network connection.
When you record music, you can master or mix them with the application. As many as 255 tracks can be used for one song. The timing of the audio can be altered, and the rhythm can be adjusted too. In the end, you can upload your final creation to Soundcloud or to your iTunes library.
Make sure you synchronize your projects to your iCloud account. This lets you modify your songs from any iOS device and allow the updates to be saved on all your devices at the same time.
Overall, It gives you so many good audio editing tools for recording tracks quickly. You can use it with your Mac to produce premium quality audio content.
Note: The demo/free version comes with a limited set of sounds, loops, and drummers, as well as no access to the Apple GarageBand Lesson Store.
