Nebulua

A simplified version of Nebulator using Lua as the script flavor. While the primary intent is to generate music-by-code, runtime interaction is also supported using midi inputs. Windows only.

It's called Nebulator after a MarkS C++ noisemaker called Nebula which manipulated synth parameters via code.

Usage

If you pass it a script file name on the command line it runs as a command line application. If not the UI is started.

The UI does have a terminal which can be used for debugging scripts using Lua debugger. See example for how-to.

Since the built-in Windows GM player sounds terrible, there are a couple of options for playing midi locally:

• Replace it with virtualmidisynth and your favorite soundfont.
• If you are using a DAW for sound generation, you can use a virtual midi loopback like loopMIDI to send to it.
