I have 20 years experience recording audio but MIDI has me confused. I bought an AVID Keystudio to help teach my daughter the keyboard and to play around with a MIDI controller in general. It hooked straight up to my IMac and was playing with the limited instruments in Garageband. Now like any true gearnut, I would like more instruments to play around with. So I would like some advice from some of you who are more experienced in this department. I was thinking of upgrading to Logic before I started playing with the MIDI stuff; would the additional virtual instruments in Logic be enough to persuade me to upgrade? How many instruments are in Logic? Also, if I google 'virtual instruments' I get all these results for plugins that help you make different noises. I thought a virtual instrument was a prerecorded sound that you selected in the software to make sounds of strings, horns guitars, drums, etc. am I not using the right terminology? I would really appreciate your help and any other insight you could provide to a guy new to the MIDI world.
