Blue is able to import ORC/SCO and CSD files and set up a Blue project file, with instruments parsed out and put into the orchestra manager, project settings set, etc. Currently, there are three options to choose from when importing a CSD file, all relating to how you would like to import the notes from the CsScore section:
Import Score to Global Score - all score goes to the Global Score section
Import All Score to Single SoundObject - all score goes into a single GenericScore SoundObject. The duration of the soundObject will be set to the duration of the imported score. This is broken up into different soundObjects and layers if sections (s-statement) are found in the score.
Import Score and Split into SoundObjects by Instrument Number - score is split by instrument number and a different GenericScore soundObject will be created for each block of score text per instrument. This is broken up into different soundObjects and layers if sections (s-statement) are found in the score.
