mml2vgm will soon support Gigatron

[denjhang]

First of all thanks to lb3361 and at67 for their invaluable advice on my Gigatron music engine to get this off to a good start. Recently I asked kuma4649 to help me realize an idea of mine to write music for gigatron using mml.

The above link shows the progress of mml2vgm's work to support the Gigatron music engine. The current demo program seems to use mml to write music and generate zgm, convert the zgm to a gigatron array, and then use my Gigatron music engine (which is a small program written in C before) to parse the array and generate music.
