Question to anyone interested:
I am running the midi signals from two merged midio128 core modules as keyboard converters to my PC running jorgan. Rather then install a computer in the console, I would like to change from midi to ethernet (cat 5), rs232 or some protocol so that I can extend the cables from the fixed PC to the console. Total distance will be about 75 feet. Any suggestions? What about wireless?
Any suggestions will be appreciated.

Per S,
The discussion above is very interesting, but one question. To my limited knowledge, the swell pedal works with the swell keyboard and on a real pipe organ, the ranks of pipes are within a swell chamber.
All approaches we have been discussing involve the total volume level coming from the sound card. Correct?
How can this be applied to only the swell keyboard and stops?

Johnc

Per S, jhenry
So if you use maintained switches for stops, if the computer is turned on with stop switches already set, the ap will not read the switches and set the stops on power up?
Jim,
A stupid question - How did you insert the .jpg picture in your reply? I have been trying to do that with no success.

Robin,
I went through the same procedure. Note in the schematics for the DIN modules that you don't need any diodes. The console that I midified has the same common bus for each keyboard. Just isolate it from the power supply and wire from the common bus to the other end of the spring wires. You don't need diodes. works fine! I wish that my little spring wires were gold plated. Having problems with poor contacts on some, and can't reach them to clean them.

Jimh and Per S,
Reflecting on both replys, if the swell shoe is part way open when the core is energized, then several of the switches are closed on power on. Will the mios app read the contacts sequentially, such tht if contact 1, 2, 3, and 4 are used for the first 4 steps and are closed, the program would send 17, 27,37,47 in sequence, ramping up the volume rapidly. If so, this should not be a problem unless you rush to press down keys very quickly after turning the power on. On the Moller swell shoe one side of the switches is a ground potential, depressing the shoe actually grounds each of the 12 leads in sequence. Is this a problem?
Jim, I did mean cresendo pedal.
regards.

Jim Henry,
I am interested in your comments of using the 12 step switches of the traditional swell pedal to effect volume control for midizer. I am completing midification of my console except for the swell pedal, and the expression pedal. Would be great to be able to operate the organ totally from the console. Per S and I have been having a running conversation about using fixed resistors in series, using the pedal contacts to short out one resistor at a time in order to get a variable voltage input to the Ain on the core. Both of us have a reservation about how successful this approach can be. Any Suggestions.
Regards,
Johnc

Robin,
I am just about complete hooking up converting two Moller keyboards for midi, one midio128 with 4 din modules, 61 inputs for the great and 61 for the swell. A second midio128 will provide for the 32 notes in the pedal and the balance for stops and presets. Almost complete wiring the swell. Both work fine with a shorting jumper. With the merger function implemented, Jim henry's Miditzer and jorgan work well. Had a bit of a problem with a stuck note, but Thorston and Per s helped fix that. Boy its just great to have experts to call on!
Cheers,
Johnc

Per S,
I think that you are correct. Someone else may be interested in your info.
Why are there multiple entries for the volume? Does the PIC convert analog to digital and the digital number set the volume? the "CO" is program change, "01" is the midi patch for volume, and the "00" thru "04" are volume levels inbetween 0 and 128?
I would very much appreciate the main.hex file. Won't be able to do anything with if very soon as we are going to the beach for the week. Taking 5 grandchildren, ages 1 year to 10. Should be interesting!!
I'll just have to dream about my organ project. Thats about the best I will be able to do. I plan to take by laptop so I may be able to get on line and tough base if I can get on the telephone line.

Johnc

Jim Henry,
Thanks for the input.
The 12 steps is not a problem. I understand what you are suggesting on the pedal end. I think that I have 12 steps on the swell pedal. I also understand about using midi notes for steps, however, what I don't understand is how the computer uses the switch contact to change the volume. What note/channel are you using for miditzer?
Regards,
Johnc

Thorston,
So there is no easy way to modify an .ini file or load an app for analog input card other then the directions you gave to Per S?
I have a Jpeg photo of my installation and would like to put in in a reply, but can't figure how to do that. Help!

Per S,
I would appreciate recepit of the main.hex file if it is not too much trouble.
Sure is a strange conicidence that we would come upon the same bug at the same time??
I have been fighting wiring problems with my old console keyboards, and had run out of possible solutions to the sticking note problem. I had even gone back to Sven Meir of jorgan and asked if it possible could be a problem with jorgan. If you haven't taken a good look at jorgan, you should. It is totally flexible!
Back to the console problems, I read on one of the forums about corrosion on the silver contacts. Evidently the original 12 volts and higher switching current kept the contacts clean. With the midibox gear operating at 5vdc, corrosion will be a problem. What's your take on that? (anyone reading this reply that has a comment to offer is welcome to jump in).
One last question - I originally planned to convert the existing swell pedal to operate as a volume control using resistors to create a coarse step variable resistor. That with 5vdc would get me a variable dc voltage to input to one of my midio128 cores. In reviewing the .ini file sample, I don't see anything about analog inputs. I have the analog input card installed and ready to go.
Regards,
Johnc

Per S, Thorston,
So I make the code change in the .inc file using notepad, save it, go thru the conversion process to .syx, then reload mios?
If it works for per s it should work for me.
Thanks Thorston!

thorston or anyone
Got a problem!
I have a midio128 core (core 00)programmed with 64 notes on the great keyboard starting with midi note 24, channel 0, and 64 notes starting with note 24, channel 1 on the swell keyboard. All notes on the great work fine. on the Swell, note 39 gets the correct "note on" message (91 39 7F) and the note plays. But, when released the note does not turn off, and the note off message it receives (monitored with midiox) is 80 10 4F which is an E1 note rather than an A3. the program sends a 91 39 00 to turn off the note. All the other notes past note 39 get the correct programme information, note on and note off. I rechecked the ini soure file and it is correct. I have another core (core 01) for the pedal thats output goes to the midi in on core 00 and the output of core 00 goes to the pc. I reprogrammed both cores again and there is no change.
I've turned the power on and off several times and Its allways the same pin on the din chip like there is a ground. If I turn on the system, I can play any note with no problem and no sticking notes. playing the A3 note causess the continuous tone on the A3 pitch.
Any suggestions from anybody!

Johns,
I'm going through the riggers of wiring 200+ keys so it late for me. However, I am interested in the diode matrix approach. Is there a typical schematic available? I don't understand how it works. How does it work for converting a common bus system found in many organ consoles? All my keys are connected to a bus and are not separable without adding new contacts, and rewiring the entire console.
your offer to custom aps programming is generous! you may be taken up on that offer!!!

Johnc

Thorston & all who helped,
Core 0X00 and one dinx4 modult are working!!
thanks for your help and PATIENCE. I appreciate it !!!
now on to the next phase
thanks again

Moebius.
Ok. I found the midio128_V2_1 directory. Did the perl routine in that directory and the only file I could find added in that directory was a main.syx file. Is that the one I download to the pic? I'm confused. What about the edited .ini file for the midio128. How does it enter the picture.
What is the mk_midio128_syx file and the sub folder 18f which has a Make command, the .ini files, etc.
I probably messed up the core, because I downloaded the main.syx file to the pic with serge's loader. Now the pic spits out a page full of acknowledge strings on power up, then stops. before I only put out one!!!
Help

Thorston,
I can't find anything on the midibox site that produces a folder or directory midio128_V2_1. I find a mk_midio128_syx from the download directory for midio128. Am I looking in the wrong place.
Also, you said to change to that directory and type in "For the MIDIO128 application: change to the midio128_v2_1 directory and type:
perl hex2syx.pl main.hex -device_id 0x01 .
Type in at the dos prompt, midi-ox, where? I entered the perl hex2syz.pl main.hex - device_id 0x01 at the dos prompt while in the directory for the mk_midio128_syx directory and got an error message that the hex2syx........ folder could not be found.
Evidently, I am not doing something correctly!

Thorston,
On my 0x00 core, on power on, I get one acknowledge string, so evidently mios is loaded. I used serge's sysex loader to load the midion128 .syx file which did something as numbers flashed where the bytes are displayed. There is not much in the way of instructions to interpret what the buttons are, and do so I assume that the midio128 .syx file loaded.
As for the 0x01 core, I had problems with perl, so I edited the file in midio-ox to change the core id number, and mios loaded ok. on power up, it also displays one acknowledgement string. When I get perl running, i will follow your instructions and modify the midio128 files to change the core id to 0X01. Again, how can i check to be sure that the midio128 ap file is loaded?
Thanks for the help,
Johnc

Thorston,
I have 2 cores, one has the ID 0 , and the other has the ID 1. Of course there are a lot of zeros infront. This is what was marked on the pic by SMASH!

Johnc

Thorston,
On my second core, on power on, I send the mios code to the pic immediately upon seeing the first string, however, the pic continues to cycle every 2 seconds. midiox output monitor shows the code was sent. I pulled the pic and shorted RX/TX and sent mios as described in the troubleshooting section and it looped back successfully. I assume then tht the opto coupler is good. all voltages and ground appear to be good! So what now?
Johnc
-
Thorston,
PIC 18F accepted mios. Also loaded midio128.syx and it appeared to load. Is there a way with midiox to tell if the app loaded?

Per S,
I will use one midil128 for the great and swell, and a midio64 for the pedal and stops. In reviewing the example ini file for buttons for the 128 it only show "90 30" for the first input. Do I have to complete the line, i.e. "90 30 7F 90 30 00" for each input pin? Also, which of the midio64 firmware should I use the "64" or the "64E". On the sample ini file for buttons on the 64E are all 64 inputs available for programming as on the 128? the first 17 on the ini example are typical then 4 more have some specific function that I don't understand. Its confusing. I want to assign 1-32 to the pedal, and 33-64 for stops. The example buttons on the ini file for the 64 shows "90 30-7F". Same question, do I add the note off part "90 30 00" for each input. Changing the channel number and note number, of course.
Thanks,
Johnc

PER S
If you enable the merger function in the configuration of the ini file for your midio128's won't they pass the signals on through to the PC. In other words, midi out of the last core to midi in of the middle core and so on, daisy chained with the midi out of the first core connected to the midi in of the PC. I am in the process of hooking up a midio128 and midio64. Two manuals on the midio128 and the pedal and stops on the midio 64 and I was going to do as I suggested above. I hope that is the correct way to set it up.
question: I'm using a moller console and rewiring the keys to the midibox digital in modules. I found a schematic for hooking up the keys to pins, however, I am confused as to which pin on the chain of 4 modules is No. 1 for the lowest note. Is it the first or the last?
Didn't realize you were in Stockholm. I am in Baton Rouge, Louisiana and the summer heat and humidity is already going bad. Our hight today will be 88 deg. f, with 80% humidity. Quite stickey!
This internet is really something, and this forum is awsome. and its great to be able to talk with someone in Stockholm, Sweden.
