Works fine on Yosemite, allows very low-level editing
You can use this tool to perform note-level editing of MIDI files. This is much more than just a MIDI player. Works fine on Yosemite on a Retina Macbook Pro.
What a relief! This one works!
This is about the eighth low cost Mac App I’ve downloaded in an attempt to be able to play MIDI files and review their contents easily. Believe it or not, it is the only the second one that even played the file. This one does a nice display on the contents, too, as you can see in the screenshots. For your reference, I’m using Mac OS X Mavericks. (Possibly that caused some grief with the other apps that I tried.)I am so relieved that I can stop downloading apps and trying them. If you use Garage Band or Logic Pro X and heavily use MIDI files, you may find this a handy complementary addition to what they can do.
Great app! I use this every day. I work with a few DAW's and this app is so good at fixing midi problems I experience. This new version lets you fix everything that needs fixing. Assign tracks fix channels etc. Thanks to the creator and the price is great for such a helper app. Support is fantastic as well.All I can say is thanks. Get it you won't be sorry.
