This is a small, incomplete wrapper around the portmidi c library.
It is the successor of my portmidi-ruby project which used ordinary ruby extensions which are a pain to write.
-
portmidi (who woulda thought) built as a dynamic library. See below for special notes for Mac OS X Snow Leopard
-
ffi (which in turn needs a sane build env to be installed)
The most important: Tests. I’m still pondering on how to test a library that has hardware requirements and dependencies (= MIDI hardware). So I guess it means I will mock away the portmidi layer to test my abstractions and add some optional integration test that will require a MIDI loopback configuration.
Implementation wise, there’s a few things missing:
-
Setting Channel- and Message filters
-
More different exceptions, plus support for Host Errors
-
A lot of safety nets like testing for open devices before reading and writing and such.

On MacOSX, there’s a homebrew recipe, so $ brew install portmidi should do the trick
-
On most Linuxes, portmidi should be simply a package to install by your packagemanager
