Music thing

This thing implements some music theory.

Install by typing rake install.

Demos

Setup (OS X)

• Open Audio MIDI Setup, click the IAC Driver and make sure the device is on and that it has a port.
• Get Propellerheads Reason 5. The demo version should work.
• In Reason, go to Preferences -> Advanced -> External Control and choose IAC Driver Bus 1 for Bus A.

Running

Mfiuegw

Mfiuegw plays music according to some rules defined in mfiuegw.rb.

Enter demos/ and open mfiuegw.rns with Reason, and start the demo by typing:

ruby mfiuegw.rb

If you have everything set up correctly, you'll hear sounds.

MIDI input

midi\_input.rb uses your MIDI-keyboard and processes the notes in some way.

Before you try it, you'll need to compile a small helper program which you can find in demos/midi_input/. Just run make and hope for the best.

TODO

• Fix note lenghts from midi.
• Refactor the midi thing.
• Beat trees should be able to be longer than one measure.
• Delegate chord selection to the midi sequence player.
• In F major, the IV should be called Bb instead of A# so that we don't get two As.
