Hi Everyone! I've searched around on these forums and found several threads with my issue but no solutions that helped my problem! Essentially, I am trying to work through "MIDI Tutorial 1: Basic MIDI," but I can't even get sound out of the basic noteout object setup. Other threads suggest that there is a problem with the AU DLS Synthesizer (although to be honest I do not fully understand what that is). I have looked into my computer's (Mac OSX 10.6.8) MIDI preferences and enabled "IAC driver." Now "IAC Driver Bus 1" is an option when I double-click on the noteout object but that doesn't seem to work either. I am running Max 5.0.6. I am totally new to MaxMSP, as well as to using MIDI, so I could really use some help! Thanks so much! --Aaron
