@ -58,10 +58,27 @@ An NES assembler for the 6502 microprocessor written in Ruby
There is an example file included (shown below) that is a modified port of
the NES101 tutorial by Michael Martin.
# MIDI converter
Included in the utils/midi directory is a my first version of a MIDI
to NES music converter, which is composed of a Ruby script backed
by a C++ program I wrote to parse MIDI files into YAML data.
At present, it can convert a MIDI file to a binary stream of values
that, when written to the APU in your 60hz VBlank, can be played
by the included sound driver code.
The idea is to be able to compose music for the NES using your
favourite digital audio workstation in MIDI, and be able to convert
the square, triangle, and noise sequences to something playable
on the NES.
