--------------------
1. VIDEO MUSIC C64 Nordlicht Party Demo emulated on Atari 2600
Group: Relational Framework
Coder: Mr SQL (Tom Babich)
File:VIDEOMUSIC_PAL.bin
Platform: Atari 2600
Demo Description:
Inspired by the Atari VIDEO MUSIC machine,
VIDEO MUSIC creates visualizations from chiptune music.
In the demo, a Simon sequencer builds a melody from choreographed Riffs.
Programmable demo:
------------------
It is possible to program the sequencer like Simon.
Or edit the music to create new riffs with visualizations,
BW switch brings up the Music Editor:
Instrument1, Frequency1 ,Instrument2, Frequency2, Frames
----------- ---------- ----------- ---------- ------
The 1st 4 fields allow values 0-31, Frames goes up to 99+
Frames will also control the bpm in increments of 16.
Joystick changes all fields and replays the pattern.
Button advances to the next pattern.
Control the visualizer with music as a programming language:
------------------------------------------------------------
If one frequency is greater than the other the visualizers horizontal axis changes,
if they are the same it freezes. Instruments control the vertical axis similarly.
This creates visualizations that pan, sweep or freeze the camera.
VIDEO MUSIC uses MBR motion blur reduction like a Movie.
Best viewing quality for MBR:
If you have an NTSC CRT Television or 60 Hz Monitor the NTSC version will play smoothly.
If you have a PAL CRT Television or 50 Hz Monitor the PAL version will play smoothly.
If you use an upscaler for a flat screen Television it must support progressive scan.
Work Stages:
The Commodore version ran on the Atari 2600 emulation Framework under NTSC.
To create a PAL version I compiled it using the Atari 2600 PAL Framework BETA.
This had the unexpected side effect of creating another raster split!
The PAL and NTSC version are both included to compare.

The BASIC and Assembly are included and ran on the Atari 2600 with no work stages!
