Last week we parsed some music. That post was in a bit of a hurry, so we had to leave off a fair few important pieces (like ties and slurs for one; chords for a rather bigger one). We’ll get to them soon, but for now we want to actually get something playing back.
It’s been a bit, but as you may have noticed life is a bit mad at the moment. But I’ve still made some progress.
When we left off last time, we’d finished the first step towards making some lovely music with Racket: tokenization. Now we want to take those songs and form them into something actually approaching music.
It’s been a bit since I’ve had time to post1, but I’ve got an interesting new project that I’ve been working on. It’s a bit more complicated, ergo spread out over a few posts, but those tend to be the more interesting posts anyway, eh?
The basic idea is that I want to be able to write and play music in Racket. One end goal would be to make a library available for the C211 class to give them something else to work with (in addition to <a href="//blog.jverkamp.com"/wombat-ide/c211-image-api/">images and <a href="//blog.jverkamp.com"/wombat-ide/c211-turtle-api/">turtles). To that end, here’s my current plan of attack2:
Sounds like fun! Let’s get started.
