Getting ready for the arrival of Dropcheck's XE Super Cart 128 with MidiMaze. For this project I decided to take a stock 16K 600XL that was badly in need of a RAM upgrade, and trick it out with MIDI in mind. To do this, I started with my SIO2MIDI board, after first shaving it down a tiny bit on the sides. This allowed me to drop it into the area where the RF modulator once resided, and would allow the new MIDI jacks to be even with the power and video jacks. I also took the opportunity to add the 64Kx4 RAM chips, and modify the addressing (some bent up IC pins and 3 jumper wires). For the new video jack I used a UAV to give it the best possible picture. And as long as I had this guy cracked open, I also changed out the Basic RevB ROM for a RevC ROM. The following pictorial documents the hardware changes required. Surgery - gotta make room for the SIO2PC, as well as strip out all of the unneeded video components. Unfortunately some traces get severed on the bottom side that will need to be jumpered. Bottom view of 'inserted' SIO2MIDI board, some required wire jumpers to replace missing traces, and all held in place by clear epoxy. Upper view showing black epoxy used between MIDI and Video jacks to add strength, UAV & RAM installed. SIO connections. Overview, all board mods completed. Adding new holes in the case for the MIDI and Video jacks. Modified board placed back in the case (front view). Modified board placed back in the case (rear view). Adding MIDI com LED (required a hole in the bottom metal frame of the keyboard) Finished look of MIDI com LED installation. MIDI com LED activated. Finished look of new MIDI and Video jacks + labeling (had to enhance the image to see the new DIN jacks). At this point the system is fully operational except for two minor omissions caused by some traces that got cut as part of the modding. That would be Audio-In on both the SIO and the PBI. Since I don't really need those for my intended application, I decided to not run jumper wires to restore them. However if that changes, I can always add them in at a later time. Now I just need my MIDI-MAZE cart, and I can link this up to my MIDI ring and start blasting happy faces .

When I started the Computer Blues Project I really thought there was no way to program the MIDI MATE from BASIC and that using the RS232 port was an option. If you don't have a MIDI Mate or MIDI Max, it is an option. If you do, there are ways of programing BASIC MIDI applications for them. I am just now starting to discover those methods. That’s at the end of this blog story. Where to start? Once upon a time….. I wasn't going to replace the MIDI Mate I sold after getting the ST but when the opportunity arose, I could only resist for about 3 months. The Wizztronics MIDI Max arrived and I was soon looking for my old MIDI Music System(MMS) song files. I unarced the song files and played some. It was like hitting the 25 year rewind. There was also a file named PD.ARC. I read over the MMS documentation again but this time the Command Summary seemed to be a little hard to read. Lots of commands on a 4.25X5.5 inch page. Retyping the chart helped me reconnect to the long term memory paths and the larger format makes for a little less eye strain. MIDI MUSIC SYSTEM comand summary.pdf I started entering some drum patterns from the book 200 Drum Machine Patterns by Rene-Pierre Bardet. That was fun but it made me realize how much effort it would take to make me an adequate drum programmer. It ain't going to happen. I'm playing with the drum kit on the Casio CTK-481. Not sure if anyone can use them. I will post the MMS files at a later date. Curiosity got the better of me and the PD.ARC file was unarched. The XMO file extensions makes me think that these are Public Domain files downloaded from Compuserve just before putting away the A8. I don't even remember reading/running them. The original XMO extensions have been changed to reflect the content of the files. PD PROGAMS atr.zip MIDIDR.DOC (MIDIDR.XMO) MIDIMate Software Interface Documentation 5/21/1985 By Hybrid Arts, Inc. This file contains technical information on the MIDIMate hardware and a listing of the fig-FOURTH source code for the driver software. (also compatible with the MIDIMax). (There are hardware schematics of midi interfaces that use the cassette motor control line to turn on and off the midi circuits. It would seem reasonable that these home brewed interfaces could be compatible with the Hybrid Arts MIDI software. (One more thing to find out.) MIDIDEMO.BAS MIDITRACK III simulated DEMO By Charles Faris This is a tutorial program for the MIDITRACK III software. It explains the screen data and most of the commands of the MIDITRACK software. HANDLR.ARC (contains HANDMIDI.DOC and HANDLER.MID) HANDMIDI.DOC The M: device. Documentation By James Dillow 1987 Released through Bitwise Computer Services This (kind of) explains the MIDI driver software that can send/receive MIDI data using standard I/O commands. It creates a M: device. It can be programed using BASIC command OPEN, CLOSE, PRINT, INPUT, etc. Or any language. (There are problems in the listed BASIC example that will make the information useless. More information and better example below). HANDLER.MID Compiled driver software. This is the binary load file that creates a M: device. Load from DOS or Rename to AUTORUN.SYS to auto boot. PATCHER.BAS CZ-101 Voice Patcher by Greg Kopchak Load and Save voice patch data to the CZ-101 MIDI keyboard. PORGAN.XMO Numeric data file - may be patch data for CZ-101 from PATCHER program????? DRTCVR.BAS (DRTCVR.XMO) Dr. T Patch Format To Patcher by Greg Kopchak Converts Dr. T tone data file to 16 PATCHER data files and a text file of patch names. HACVRT.BAS CZ-Patch Format to Patcher by Greg Kopchak Converts Hybrid Arts CZ-PATCH tone data to 16 Patcher data files and a text file of patch names. CZMIX.BAS CZ-101 Voices By Greg Kopchak I think this is a voice mixer? for the CZ-101. I had a CZ-101s but never used this program to edit voices. SSBMID.BAS (SSBMID.XMO) Star Spangled Banner by Francis Scott Key Program by Greg Kopchak 11/86 BASIC program to play Star Spangle Banner. Says "Requires Midimate and CZ-101". There are Program Change messages that call specific voice patches on the CZ-101 which may or may not sound good on your synth. There is a 270 byte machine language routine and a lot of poking into the IO routines. Have yet to figure out how the program works. Disk IO did not work after program is stopped using the break key. ------------------------------------------------------------------------- The M: device - HANDLR.ARC This file called to me and I had to give it a try. The resulting program is in an zipped .ATR image. MTEST.BAS will play middle C three times, if the driver is loaded and your MIDI system is attached. midi device test atr.zip The MIDI Device Test.ATR is in 720 sector format with DOS 2.0s and MEM.SAV. The HANDLER.MID is the binary load file that installs the M: device onto the computer. The M: device can then be accessed like other devices within a given language. The HANDMIDI.DOC is the documentation on the M: device and example program. The BASIC example program has several errors and will not be of much help. AUTORUN.SYS is a copy of the HANDLER.MID file and sets up the M: device driver at boot up. MTEST.BAS/.BTX is the Atari BASIC test program. 10 REM OPEN CHANNEL-START CONCURENT 20 OPEN #1,13,0,"M:" 30 XIO 40,#1,0,0,"M:" 40 REM PLAY NOTES - NOTE ON 45 FOR Y=1 TO 3:REM PLAY NOTE 3X 50 REM NOTE ON:MIDDLE C:VEL=100 60 PUT #1,144:PUT #1,60:PUT #1,100 70 FOR X=1 TO 50:NEXT X:REM DELAY 80 REM NOTE OFF:MIDDLE C:VEL=0 90 PUT #1,128:PUT #1,60:PUT #1,0 100 FOR X=1 TO 50:NEXT X:REM DELAY 110 NEXT Y 120 CLOSE #1 130 END There are three problems with the example given in the .DOC file that needed to be addressed to get middle C to play. a. The AUX1 in the OPEN Command should be 13. "13" is the same number used to set up concurrent in and out mode on the 850 interface. b. The AUX2 is missing from the XIO command. AUX2 = 0. This is a syntax error if you enter this line in Atari BASIC. c. The Note on and Note off MIDI commands require 3 bytes. The command number+channel, note number, and velocity. The example only shows 2 bytes being sent. Once these changes were made, the note came on and turned off 3 times. The CLOSE #channel and END commands are to made sure the program ended properly. Try it on your MIDI setup. Or better yet, write the nxt-gen MIDI game.

A MIDIMate interface for the Atari 8bit computers. Plugs into the SIO port. Works with MIDI Music System 1.0 and MIDI track III. Includes two 1/4 " to RCA adapers for the Sync In and Out ports. Includes original disk and manual for MIDI Music System software. It also can convert AMS music to MIDI format that is uses. (.MUS file extension.) Includes a CD of the entire archive of the 3000 public domain MIDI files that can be played with this interface from the Action Annex BBS. I was co-sysop for a few years back in the day. This was the very same interface Donna used to make audio tapes and test her composition. How's that for maximum compatibility? Since all the MIDI Max interfaces are sold out at Best Electronics, this may very well be one of the last few times you will ever find a vintage equivalent interface like this. Until someone remakes the interface for the 1088xl or finishes the reverse engineering of an equivalent. SOLD!
