[Coco] 83,797 MIDI Files..........

[Glen Hewlett]

Hey Guys,

There is another option coming soon to a CoCo near you!

I’m currently working on a MIDI converter that will take both MIDI format 0 and a format 1 and convert them to music data that can be played back on the CoCo using either of these methods:
1) Simon Jonassen’s software dipole.asm player (2 voices at this time.  Simon has other programs that can play more voices.  I’ll add that when available)
2) John Linville’s Game Master cartridge, using a format and player I wrote (3 voices and a noise channel)
3) Ed Snider’s CoCo PSG again using a format and player I wrote (3 voices, any channel can also be a noise channel)
All the above sound options use Square Wave’s for the instrument sounds.

Both options 2 & 3 use very little CPU usage as they are hardware based.  My hope is that with the converter Game programmers will be able to add some nice background music to their games and also CoCo users can just have fun playing music on their CoCo’s

My converter is a QB64 (compiled basic) program that will run on Linux, Mac or Windows.

The software is progressing well.  I still have to work out noise effects for drum type sounds on Ed’s CoCo PSG.  I want the converter to output the player and music data in a format that can be easily used on the CoCo.  I’m thinking that I’ll ask the user what CoCo they have and how much RAM and based on their responses output a .asm file with the player code and the data ready to be assembled and used on a CoCo.

It’s great timing to have these MIDI files available.  Thanks Guillaume Major and Joe Schutts :)

Here are a couple links to see/hear the output of my converter:
