What is Syd?

Syd, short for "Synthesis Demonstration" or "Synthesis Donut" is an instrument editor and software synthesizer ...
Features:

• Graphical Interface for patching instruments and creating scores. 
• Some of the same power than can be found in text-based Music-N languages, such as CSound.
• Provides mechanisms so instruments can be edited and tested without the need to generate a score.
• Unlike Music-N languages, a score is treated as just another sound generating unit, which simplifies many operations.  For example, one score can play another score as an instrument, and its output can be fed to a reverb module or amplifier, for post-processing.
• The "Random Score" can generate sequences of random notes, as well as make permutations to an existing CSound score.  For example, it can cause each note in a CSound score to trigger 100 simultaneous notes with slight variations in the parameters.  It can also be used to augment or rearrange the parameters in a CSound score so it can be used with instruments which require alternate parameters.
