Grace is a graphical algorithmic music composition environment that creates sound by transforming high-level algorithmic representations of musical processes and structures into a variety of control protocols (e.g. MIDI, OSC, Audio, MusicXml) for sound synthesis and display. Musical algorithms run in real time, or faster-than-real time for file-based composition. Grace provides two languages for coding musical processes: its native S7 Scheme, and SAL, an easy-to-learn but expressive scripting language.
Incredible tool for generative music
It has a bit of a learning curve, but after going through the helpful and in-depth tutorials and examples, I’ve been able to make a few simple programs that I was very satisfied with. The ability to play midi programs directly from the editor is great for finding bugs and makes composition more intuitive. This program is very extensive in scope and I look forward to making more complex compositions. Oh yeah and you can compose in quarter tones or eighth tones or whatever the hell kind of tones you could ever think of, which is cool.
