Random Computer Music

[zackrspv]

So, after looking at the MIDI UDF, I decided it would be fun to generate some random music, etc, based on the process useage of the 'System' PID. (It normally is the first one pulled by the ProcessList() command anyway.

Features:

1. Random Instruments or Only Grand Piano (UI selectable)

2. Chords and Single Notes at random

3. Chord/Note hold times are random

In all, it doesn't sound too bad, and as it's based on the Memory Reads and IO's and some rather random calculations, you never can predict what notes will help when, and how long they will hold for, or how many chords will be allowed to play at once lol

It was just a good time waster. I'm sure i did many of the things in here rather LONG, but hey, that's me, pretty pragmatic when it comes to making stuff. The GUI is a bit flakey, ie sometimes you have to press a button 2 or 3 times for it to register, only because of all of the sleep commands.

I'm thinking of making it to where it can generate the sounds based on Internet usage too lol think that'd be pretty cool.

If you can think of anything to add, whatever, let me know.

Edit: Sounds better as: Sleep(Random(Int(Random(200, 400)), Int(Random(400, 900)))), so, changed script to reflect that.

good job!

good job!

thx!

lol, thanks. It's not meant to give you actual 'music' to listen too; just random midi tones based on the useage of your machine, but was interesting to create.
