I find it is a little hard to use, garageband is so simple and fast but also too limited. . . Is logic express the only option? Are plugins not available for GB?
Yeah, there's some depth there (an understatement) but that's exactly what makes Logic Express "simple and fast."
Well, ok, maybe not simple, but definitely fast. One of the shortcomings of GarageBand that forced me to upgrade was the lack of keyboard shortcuts and sophisticated navigation tools. Off the top of my head, here are common tasks I can do in one key combination in Logic Express:
1) Start the playhead from the beginning of the song, or the current location, or the beginning of the current selection (region).
2) Zoom into any selection I draw with my mouse. And then zoom back out to the full arrange window. Or zoom back to the previous zoom level, whatever it was.
3) Create a fade in/out of arbitrary length and then adjust the curve with another mouse drag/key combo.
4) Open the mixer, loop browser, instrument library, audio bin, score window, audio editor, etc with just a single keystroke.
5) Select any audio region or part thereof, drag it to a new location, and dynamically choose whether this operation will *move* the audio or *duplicate* it. My choice, just by pressing the option key.
Obviously this just scratches the surface. Even if you were uninterested in the effects, synths, automation, and manipulation tools included in Logic Express, the navigation time savers alone are worth the price of entry. It's unbe-frickin-lievable that Apple sells their Prosumer apps (Logic Express, Aperture, Final Cut Express) for 200 clams. Less if you've got access to educational discounts.
Anyway, if you're looking for more power out of GarageBand, Logic Express is the ticket. I found this book very helpful:
