Reddit Holiday Music Week VI

Postby Fletch » Wed Dec 19, 2018 4:19 pm

I've submitted an Atari ST entry into the /r/Retrobattlestations Holiday Music Week contest on Reddit.

​I wrote a program in GFA BASIC on my Atari ST that plays Silent Night on my Roland MT-32 and displays a picture of Christmas Balls I photographed with an Apple QuickTake 200.

I needed to learn how to program MIDI control codes as well the corresponding MIDI notes. I had difficulty locating any information on how to do this from BASIC, but through trial and error and quite a bit of luck was able to get the MT-32 to play the tune. I am not very good at reading music, so the process of creating a tune was long for me. I'm sure it would be much easier for someone who can actually read music.

I then imported the photo in to my ST via the ComputerEyes Digitizer and saved the image as a Neochrome file.

Once that was done, back in GFA BASIC I added some code to load the Neochrome pictures into the program. I then added some some lyrics and text and set up the video shoot for the contest.

I am not much of a programmer, but enjoyed learning how to make the MT-32 make sounds and then making it play a tune from BASIC.

Below is a link to the video as well as the Reddit post.

Nice, I like MT-32. Do you use voices fdrom default sound bank or did you programmed them?

It is the default bank. Since I do not read music very well, just figuring out the notes and their lengths was hard for me. I found a site that explained the MIDI ON/OFF codes as well as the MIDI note numbers and that was very helpful. I'm sure I probably messed up a few, but I think it sounds pretty good to my non-musical ear.
