MIDIs are all I know how to make so far. My usual process is "goof around on the piano, find something that sounds nice, rush to recreate it in Anvil studio". I've accumulated a couple dozen MIDIs this way, most of them unnamed, really short and not to be considered full-fledged songs (which is why I like to call them "musical notes").
Many of these would probably sound repetitive and flat to the sophisticated ear. I do think they're listenable, though.
Here are some of the ones I like best:
Happy And Safe
As an amateur I like playing on the black keys only, because there's very litle risk of dissonance there. This is one of the better songs to come out of that. There's a key change at one point, which may or may not sound cheesy.
And All That Before
Breakfast (2012, 2014)
A nice "all's well that ends well" kind of melody. It's a lot better than what I usually come up with, and I can't shake the feeling that I subconsciously stole it from somewhere. The chords to it are simple, but I'm proud I found them!
Very little going on here other than atmosphere, but it came out surprisingly well! This one keeps giving me "underwater" vibes, and I'd be thrilled if it worked as a water level soundtrack in some kind of video game.
Working title: "N" (2013)
This has always been a credits theme in my mind. The chord progression here is actually pretty complex (for my standards, anyway).
Working title: "JZ" (2014)
It was quite a surprise to catch myself using a blues scale out of the blue. (Not sure if I knew what it was at the time, I probably just went with what sounded right.) I'm still not sure where this came from — all I know is it's a mess in the MIDI editor.
Working title: "CH" (2014)
This one's in 5/4 time for some reason? I'm pretty happy with the melody and the harmonies in what could pass for the chorus.
Good Job (2015)
A slow buildup to what I think is an alright melody. The bass line closely resembles that of "JZ", which is on purpose as far as I can remember. I totally forgot where the name came from, though.
Working title: "DE4" (2015)
This one's basically just alternating D and E chords underneath a melody they never asked for. The part near the end is just a 4/4 version of a piece of "CH".
City Lights (2017)
There's not a lot to this one, but I think it sounds positively "dark" and "cool", for lack of better words.
Working title: "NT" (2018)
This is another one where I found the chords on accident. It sounds like it wants to be an intro from an old-school RPG or something.
