Jubilation -- a 2022 piece for piano done in MuseNet
MuseNet is still dead. This is a revision of a piece I did on my third day of using MuseNet back in August 25, 2022. It was done in the Chopin style, but doesn't sound much like Chopin. I edited the MIDI for this revision doing a lot of improvements in the piano performance.
For MIDI software, I'm now using the free Waveform 13 DAW by Tracktion, and I highly recommend it. If you've used another DAW's MIDI features, Waveform will look familiar and not be hard to learn, if you watch a few videos on it. However, if you haven't used a DAW before to do MIDI editing, it can take a month or more to learn.
I found a free piano VST sound that rivals ones costing hundreds of dollars. It is called the "American Home Grand" by Arturia. It comes in their free Analog Lab Play package of instruments, which is about 5GB in size and full of synths and other instruments I'll probably never use.
The two settings to tweak on the Arturia "American Home Grand" sound are tone and reverb. The default tone is a little too bright, and the default reverb is a too dead.
MuseNet by OpenAI was discontinued in December, 2022.
Since MuseNet is dead, I've been using AI software on GitHub having composed over 100 pieces, making my total output of AI works at over 200 in the last three years, but Alex has also written over a dozen easy-to-use apps for AI and MIDI on his HuggingFace page:

Huggingface apps are very easy to use. And you can download your result in MIDI in the lower right-hand corner in the MIDI section, where it has a small number for the size of the MIDI. There are different apps for "inpainting" a MIDI, creating a MIDI seed of your own, and adding harmonies and various other things to a MIDI. Signing up (which is free) on HuggingFace will give you more time, as the apps time out sometimes if you keep generating files on them for more than 45 minutes or so.
