My first mp3 created using:
1. Band-in-a-Box to generate the MIDI and scoresheet
2. Garage Band to play the MIDI using its inhouse sounds
3. Garage Band to export it to an mp3
4. Podbean to host the file
Nothing was actually 'played' live by me - it's all programming. Next attempt will be to actually play some tracks in real time and record them using Garage Band.
Start of music experimentation, day 1.
