- HAMmmm2 by Phil Burk
-
- HAMmmm2 is in the public domain and may be freely redistributed.
-
- HAMmmm2 is an updated version of HAMmmm. It adds two new graphic
- drawing modes, "boxes" and "star". It also changes
- the intervals in the chord, and has updated addresses.
-
- HAMmmm displays lines, or boxes, whose end points are bouncing around
- the screen. The screen is a double buffered HAM screen.
- The top is painted with the HAM color "set red to zero".
- The bottom is "set blue to zero".
-
- The y positions of the points are continuously copied
- into an audio waveform that is played on all four
- channels. The pitch of a just intoned chord is derived
- from the average x position of these points.
-
- This demo grew out of a short piece written for the
- recent Harmonic Convergence. I played a four part
- celestial sounding chord using the Amiga local sound,
- and put a blank formatted disk in drive 1. My hope
- was that when the galactic intelligence beamed it's
- message to Earth that I would capture it directly
- on disk and not have to type it in. :-)
-
- This Demo was written using JForth. JForth was
- written by Mike Haas, Brian Donovan and myself.
- The sound portion used the local sound toolbox
- from HMSL which I wrote with Larry Polansky
- and David Rosenboom from the Mills College Center
- for Contemporary Music. You can compile HAMmmm,
- without sound, using just JForth. If you have
- HMSL you can compile on top of that to get sound.
-
- If you would like to compile HAMmmm, start either JForth
- or HMSL as you are accustomed, CD to the HAMmmm directory,
- then:
-
- INCLUDE LOAD_MMM
