As a lover of music, programming, and calculators, I'm always looking for ways to combine the three! Though I've wanted to do this forever, last week I finally decided to get to work on a program which allows you to enter notes in music notation, and play them back through the linkport! Currently, you can only enter quarter, eighth, and sixteenth notes, but it renders them using proper stem direction, note grouping, and ligature marks (the lines that connect eighth and sixteenth notes). Oh, and beats line up! Here are some screenshots of score in action (the inverted portion is where the cursor is):











Of course, I still have a lot of work to do, but I'm happy with how it's turned out so far. Right now, I need to fix the stem length for sixteenth notes, since the ligature marks can make the stem look too short (for example, second screenshot, first group of sixteenth notes, last note). Also, I need to add thirty-second notes and rests. And music playback is an eventual goal, which will use Ben Ryves's sound routines for 4-channel sound. But it's not bad for a start! 


Now, I have a question for music-savvy people. In the first screenshot, the first two eighth notes are connected by a ligature mark to the following four sixteenth notes. Is this correct, or should they be separated?

They should be separated, assuming this is x/4 time, where x is anything.

No, they're grouped based on what gets the beat. 6/8 is groups over the duration of 3 eighth notes, 4/4 over 2, etc.

GlaßOS is in C.

Nope, the author says he's not good enough for asm.

Dude, you are exactly like me. I love composing/playing music, calculators, and programming. Need any help with this project?
