Out of the Pack

Finally, I'm Playing MIDI Notes using MAC/65 Assembler Code

MIDI, Arduino
Do you remember me mentioning that the first attempt to write a machine language program to  read MIDI data delivered to the Atari joystick port was a complete failure?  The Arduino hardware has remained the same. The joystick trigger and cassette motor control(CMC) pin on the SIO port are still being used to control data flow.  But this ti...

SAM sings a round

SAM sings a round There was a Korg microKorg under the Christmas tree last year; only because my wife wouldn't let me set it up in November when it was purchased.  I did manage to get the manual out of the box before it was wrapped.  So for a whole month I read the manual and watched youTube videos.
The microKorg has a vocoder.  This suggested that th...

A journey to Bach's Invention 1 and other miscellaneous updates

A journey to Bach's Invention 1 and other miscellaneous updates After recording PRELUDE1.MP3 it seemed that the Atari BASIC sound program needed to be reprogrammed in assembly.  I got out the MAC65 cart and two days later things were so messed up I wasn't sure if it was the Arduino and/or Atari software or the Arduino interface hardware giving me the headaches. 
I decided to go back and setup the equi...

AMS v1.0 Command Summary and Stereo Recording

AMS, Bach, stereo
I've started a project to recreate W. Carlos's Switched on Bach album playlist using the Atari8  as a sound source.  A goal on my bucket list is to finish it.  I intend to use the MIDI Music System to send data to other Ataris that will act as sound synthesizers.   My original thought was to have the ability  to play the song...

MIDIPLUS miniEngine USB - first impressions

MIDIPLUS miniEngine USB - first impressions I ordered the MIDIPLUS miniEngine USB sound synthesizer to reward myself for doing something special.  This is the first chance I've had to play with it and can't remember exactly what that something was.  Maybe it wasn't that special.
The thing that interested me most about this general midi sound module is its size( 3" X 4" X 1"). ...

DB9 Experimenter Box

DB9 Experimenter Box Someday I'm going to take a photo while experimenting with DB9 connectors on the Atari Joystick ports or RS-232 ports and this box is going to be in the middle of a mess of wires.  Some one is likely to ask,  "What's up with that box?"  This is an attempt to have this information ready to answer that very question.

Metronome - Software Timer Demo in DE RE Atari

metronome, software timer
I was thinking about making an 8-step sequencer for a Gakken SX-150 Mark II analog synthesizer using the Atari8.  Then I thought, "Why not just use the Pokey chip instead of the Gakken? "  Then I thought, "Why not develop it using Diamond GOS? I'll bet no one has done that yet." 
While reading up on the hardware and software timers,...

Kaleid-a-vision: A Music Visualizer Technique for Retro Computers

I can't say I did this on my Atari8, but I can truthfully say I did it with my Atari8.

This video was recorded using the Kaleid-a-vision hardware, Atari8 and video camera.  I would suppose any retro computer or video game machine could be used as a video source. 
The Atari was running a GR9 Demo...

DH100 - A POKEY House of the Rising Sun

DH100, Arduino, MIDI

I finally put together a semi-live performance using the DH-100 Digital Horn to control the sound of an Atari XE computer.  I know that improvements to the hardware/software is not going to improve my ability to play the horn but there is much that can be done to improve the sound.
There were some cha...
