Switched On Pokey - Epilogue

My Catch-22:  If I knew what I know now, I am not sure I would have started this project.  But If I didn't start this project, I would not have learned what I know now.   It seems like it has taken forever to finish the tracks but I'm not sure when it started.  In October 2018 the prologue was written; that's only 10 months.  If you consider I started experimenting with programing MIDI, it started when "Computer Blues" was modified to output midi commands through the 850's RS232 port;

S.O.P. Track 12 - Brandenburg Concerto No. 3 In G Major-3rd Movement

Since the Switched On Bach album was released in 1968 and the Atari 800 was introduced in 1979, it seemed fitting that I would should start with the 1979 Atari and fade into the 1990 Yamaha TG-33.     Brandonburg #3 third move.mp3   NOTES: Music File origin:   Sheet Music VBURGM3.MUS for Atari RECORD.MUS  for TG-33 RECORD.INF    for TG-33 channel assignments                        Control Computer: 130XE       Sequencer Software:  MIDI Music Sys

S.O.P. Track 11 - Brandenburg Concerto No. 3 In G Major-2nd Movement

Bach had the idea to write the second movement  as 2 cords in one measure.  Some believe that it was a place holder and Bach was going to finish the second movement at a later date and others say it provided a musician a starting point for improvisation.   Wendy Carlos created a track that had me thinking her efforts were directly influenced by Bach's spirit.  I'm not so lucky (or maybe your not so lucky).   I took the notes of the cords and arranged them in sequence to produ

S.O.P. Track 10 - Brandenburg Concerto No. 3 In G Major-1st Movement

A major rewrite of the Arduino/Atari communication software was accomplished.  It seems the Cassette Motor Control pin causes a spike when it switched.  (You can hear it in some of the previous tracks.)  BIT 7 of PORTA has been configured for output.  Joystick 2 trigger can be used as BIT 7 if its ever needed.   It took a couple of weeks of software trouble shooting to figure out that the hardware was the problem.  The output power from the CMC was enough to trigger the optocoupler but

S.O.P. Track 9 - Chorale Prelude "Wachet Auf"

A little tremolo was added to SINGLEBYTE.M65. It is subtle but hearable.

S.O.P. Track 8 - Prelude and Fugue No2 in C Minor

Seems the simpler the program the more I like the result.

S.O.P. Track 7 - Prelude and Fugue No7 in E-Flat Major

This track may seem a little plucky but if you listen to the tracks in order your ears may become conditioned to the point where it doesn't sound half bad. Or maybe not. prelude and fugue No7 in E-Flat Major.mp3 All the rest of the music has been entered into the MIDI Music System and is ready to record once some new sounds can be programed. For this track minor changes to the BASIC software was made to give a quick pluck or hit sound. I was a little supprised that a delay loop was need

S.O.P. Track 6 - Jesu, Joy of Man's Desiring

Looking forward to seeing what's under the tree, so until then…….. Jesu Joy of mans desiring.mp3 Jesu, Joy of Man's Desiring has been in the archives for quite some time. I don't believe there is anyway to track down the origins of this MIDI MUSIC SYSTEM file. Who ever is responsible, I would like to express my gratitude. Although, I didn't use the file as is. The music seemed to be duplicated and the midi controls were changed for different MIDI equipment. These extra voices were delet

S.O.P. Track 5 - Two-Part Invention In D Minor

Back to basics. I decided to do this track without using the MIDI setup. Track 5 was recorded using a 130XE running The Music Studio developed by Audio Light, Inc. and distributed by Activision.   Two-Part Invention in D Minor.mp3     My first experience with Music Studio was on the ST. I saw the A8 version at a rock bottom price and added it to my collection. This isn't a review but let me say I was less then impressed and never got passed a cursory look before its abandonment.   Th

S.O.P. Track 4 - Two-Part Invention In B-flat Minor

Bach's Invention #14 The ADSR is modified for this track. Mostly the S and R but only slightly.

S.O.P. Track 3 - Two-Part Invention In F Major

A.K.A. Invention #8 Still working with Atari BASIC to create the sounds. This time a couple of FOR-NEXT loops were added to give a little attack and decay to the notes before it was compiled. The Program does some pretty strange things to the notes when used with a MIDI KEYBOARD but works OK as long as a note get turned off before the next NOTEON command. Luckily the MIDI Music System does this.   Two Part Invention in F Major.mp3     Music File origin: INVENT08.MUS

S.O.P. Track 2 - Air On A G String

I wanted to set track 2 up as a duo between the Atari 800 and a friend with a Cello. Pairing the Atari with the Yamaha TG-33 ended up being the easier option. Besides, it was also easier to use the effects processor in the mixer then renting a cathedral. Maybe that friend would have called back if I had left him a voice message.   Air On A G String.mp3       Music File origin: AIRFOR.MUS - Deleted Voice 3 - Delet

S.O.P. Track 1 - Sinfonia To Cantata No. 29

Or would it be more impressive to say , Sinfonia dalla Cantata n.29 Trascrizione da Concerto per Atari 800 Sinfonia to Cantata No29.mp3 This track was produced using one Atari 800 for all its sound sources with a little FX provided by the mixer. Two of Atari's sound channels were combined to allow defining frequencies using 16 bits. The MP3 is the combination of 6 tracks recorded with multi-track recording software. ----------------------------------------------------------------------

Switched On POKEY - Prologue

Earlier this year I declared my intentions to recreate the sound tracks on W. Carlos's Switched on Bach album using Atari8 computers. I wish I had started earlier. It would have been a fitting tribute to Carlos's work if I had finished it on the 50th anniversary of its release. I hope it is still a fitting tribute when it is done. Released in 1968, eleven years before the Atari 800 was available. Electronic music generation was just in the experimental stages and being defined by a few musi
