Terminal window 1:
$ gs -sNOSAFER tetris.ps
Terminal window 2:
$ stty raw -echo; cat >> t.txt
Play with arrows and space bar in window 2.
The program write MIDI commands in midi.bin.
You can read midi.bin from a helper script to send the commands to a synthetizer.
On macOS, you can use GarageBand and the brigde midi.py:
1. in "Audio MIDI Setup" application, open "IAC Driver" and check "Device in online"
2. in "GarageBand" application, create a new empty project with a MIDI track. "8-Bit Grit" instrument works fine.
3. run `tail -f midi.bin | python3 midi.py`
