For Alex and Lydia remix we wanted to use the midi composition and just swap the instruments and adjust the notes to suit the different feel the Sample based instruments gave. So to be able to reuse all of the mdi notes we needed to merge the instruments I made and the midi that Lydia made meaning we needed to make two projects become one.
So we decided the easiest way to go about this would be to drag my instruments into lydia's project by dragging and dropping my project into Ableton’s project files section and then going through the folder to locate the ALP (instrument) files and dragging them onto the timeline loading in the respective MIDI instruments.
