Hi, I was wondering what equipment I would need if I were to record basic samples of my songs..my budget is small as I am still a student. Basically would like to know if there's a certain piano keyboard I could purchase and plug in to my macbook, and record with software which would recognise the notes played so that if I need to edit them afterwards I could. The software would also need to be able to change the sound to sound like another instrument e.g. bass, guitar etc. I also need a really simple mic to record with - would the internal one on my macbook suffice? Is there anything else you think i've missed out? Thanks in advance.
