Luna

Luna is a MIDI sequencer, built on top of Löve2d, tightly-coupled with my electronic music hardware and particular my modular synthesizers.

It features:

multiple parallel sequences sent to different channels
staff notation representation of sequences
live code reloading
ability to take advantage of portamento settings to create ties between notes

You can see it in action in my newer YouTube releases:

Things I did to get this running

These are some notes I made for myself in order to get my setup going on my Macbook. Maybe it'll work for you too? Good luck.

Built lua 5.1 from source:

curl -R -O http://www.lua.org/ftp/lua-5.1.5.tar.gz
tar zxf lua-5.1.5.tar.gz
cd lua-5.1.5
make macosx install

I needed cmake. Got it from brew.

Built RtMidi. It was necessary to patch a missing semaphor function with a an open-sourced replacement. Copied the file into the src directory, deleted #include "sem_timedwait.h" because that header file is empty, and added #include "sem_timedwait.h" below the semaphore include.

Ran these commands (from the readme)

./autogen.sh
./configure
make

cmake told me I needed some things. brew installed them just fine

Next I built luamidi. There are two libraries with this name, which confused me for a bit.

This isn't compatible with lua 5.3.

Instead of running make, I added a rockspec:

package = "luamidi"
version = "1.0-1"
source = {
   url = "." -- not online yet!
}
build = {
   type = "make"
}

and ran luarocks make

copied luamidi.o into into the src directory

Also pulled down the source and build luafilesystem, creating lfo.so
