First of all, the mastermind of the project described me what kind of songs she had in her mind, and after I started working on Logic Pro X at the midi structure for each single instrument. Then I created the entire tracks and I managed the recordings of piano, keyboards and orchestral arrangements using VST or sounds taken from my synth Yamaha and Korg. Finally I exported all the audio tracks that I worked on, and sent them to the composer in order to be mixed and processed externally.
