Question: GarageBand and live sound w/mic
Equipment: (Late 08)Apple MacBook Pro, (2)Samson hi dynamic mic & recording mic USB input, Samson Auro X12D powered speaker(2 XLR inputs). TRS adaptor for iPhone SE
My main question is, can GarageBand allow the editing menu, i.e. Master echo/reverb, Autotune, Compressor, Flanger type settings etc. come thru a live vocal singing/practice? Recording mic has a USB, I plugged the speaker in the headphone jack of MacBook...not working...Next, I plugged the other mic into the speakers XLR input and speaker to MacBook..Not working.
Unsure about interface or mixer, due to not having one yet. Plus, I've messed with the GB preferences also.
BTW: I also have a Early 17 iMac if that has something newer I don't know about for this issue.
Thanks for any guidance.
MacBook Pro, Mac OS X (10.7.4)
