I used this software some time ago to edit a couple MIDI files with mouse and (computer) keyboard, mainly for altering melody tracks, fixing some wrong chords and adding drums. I found this tool pretty intuitive to use and liked it a lot.

I had previously tried Sekaiju and another tool whose name I forgot, but I felt like they were aimed at more experienced users and assumed a higher level of knowledge about MIDI terms and concepts (of which I know very little), so much of the interface went over my head. MIDI Editor was good enough for my simpler use case.

I compare it to Paintshop Pro: it may not be Photoshop, but that's an advantage if you don't actually need Photoshop.

I'm still curious about what did Altman do that could've been so heinous as to prompt the board to remove him so swiftly, yet not bad enough to make his return a complete impossibility. Has there been any official word on what was Altman not being candid enough about?
