General MIDI Player is an easy way to turn your Mac into an instrument, using its built-in General MIDI support. Starting in version 2, it also plays back type 1 General MIDI files!

You can play the General MIDI instruments using either your mouse, computer keyboard (including support for non-US keyboards), or MIDI device (both hardware and software MIDI devices supported). You can even play along yourself while a General MIDI song plays at the same time. It has a simple, one-screen interface, that will let you start making music with your favorite General MIDI instrument in seconds!

What’s New

Version 2.2

* Combined keyboard & mouse entry into single mode

Worked for a while then stopped

I was using this with an iRig Keys and it was fine, then today it just stopped working. iRig still works with other software (Logic, Finale) so that's not the issue. Did a restart and a re-install - no luck. Oh well. It did work for a couple of months, anyway.

Great app, and responsive developer!

It does what it says on the label. And when I requested a new feature (ability to play the drum kit on MIDI channel 10) they implemented it! Yay!

Simple, effective, inexpensive MIDI Player

This is an excellent little program if you just need to play sounds on your computer
1) mouse on screen keyboard
2) MIDI controller keyboard input
3) computer keyboard

The interface is VERY simple, so it’s incredibly useful in just getting your
MIDI controller up and running. I had problems with other music programs —
they have complicated interfaces with buried, obscure settings
and I could not get the computer to recognize
my little MIDI keyboard (LPK25) in order to play sounds.

If you can’t get the hardware to produce a sound at all,
you can’t get off the ground, and it’s very frustrating.

For playing MIDI files or composing, editing, and playing MIDI files from MIDI keyboard
I recommend Aria Maestosa.

Make sure you
1) choose the right MIDI channel (if “any” doesn’t work, try 1)
2) sound output(click on speaker icon below Output) is turned on (OFF is the default — I would suggest that ON be the default)
