After receiving the request of the songs form the mastermind of the project, I started working on Logic Pro X at the midi structure for each single instrument. I worked on the arrangements of the original track, in order to improve the structure.
Then I recorded the 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.
