The concept of SoundObjects is the foundation of Blue's design in organizing musical ideas. This section will discuss what is a SoundObject, how this idea is implemented in Blue, and strategies on how to use the concept of SoundObjects in organizing your own musical work.
What is a SoundObject?
SoundObjects in Blue represent a perceived sound idea, whether it be a single atomic sound event or aggregate of other sound objects. A SoundObject on the timeline can represent many things, whether it is a single sound, a melody, a rhythm, a phrase, a section involving phrases and multiple lines, a gesture, or anything else that is a perceived sound idea.
Since there are many ways to express musical ideas, to fully allow the range of expression that Csound offers, Blue's SoundObjects are capable of generating different things that Csound will use. Although most often they are used mostly for generating Csound SCO text, SoundObjects may also generate ftables, instruments, user-defined opcodes, and everything else that would be needed to express a musical idea in Csound.
Beyond each SoundObject's unique capabilities, SoundObjects do share common qualities: name, start time, duration, end time. Most will also support a Time Behavior (Scale, Repeat, or None) which affects how the notes generated by the SoundObject will be adjusted--if at all--to the duration of the SoundObject. Most will also support NoteProcessors, another key tool in Csound for manipulating notes generated from a SoundObject. All SoundObjects also support a background color property, used strictly for visual purposes on the timeline.
