Hello! This is my first post in the audio forum. I assume this is the best place to ask a few questions. I cruised the forums but did not find a complete answer to each individual question, so's I assumed I could smash them all together here. I am looking to learn the piano, but mostly to learn it for experimental/dabbling reasons. My goal is to get some kind of MIDI controller (88 key with realistic piano tactile feel) that can plug into Garageband and allow me to meddle with different things. I am an experienced guitarist, but I know nothing beyond guitars and amps; the music world in terms of computers is a foreign land to me. So, here is what I would like to know (if anyone could lend a hand): 1. Recommendations for a good, hopefully affordable MIDI controller with 88 keys and realistic piano hammer-action that will work nicely with Garageband. And, do these things work with external amplifiers for use as keyboards, or not? 2. Is it necessary to get some kind of audio interface for the MIDI controller or can I simply plug it directly into the mac with the help of appropriate plugs/adapters? 3. any good books for someone interested in learning the piano? 4. Would it be possible to run Garageband along with the proposed setup above through a G4 Cube or would I need something beefier? Thanks very much in advance!
