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:
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
