  1. Ok, I follow your wanting to midify the pedalboard, but "making the pedals hit the white keys of an M-Audio keyboard..." eludes me, especially the "hit" Do you want to play the m-audio board system from the organ pedalboard, or play the pedalboard notes on the organ from the M-audio keyboard? Midifying the pedalboard to add contacts which can be wired to an encoder is easy. modifying the m-audo keyboard to insert a contact, or to modify the internal circuitry is something else entirely. Can you clarify exactly what your intentions are. In the meantime, you may want to sea
  2. Do I understand you correctly? All you want to do is strip out the "innerds" of the old Hammond, except for the on/off/vol knob,and use the cabinet for some other purpose? You say you want to convert it to a midicontroller, which is very general, and very confusing. To do what? Exactly what are you trying to do that you need a midicontroller? Are you referring to a midibox core 8, or an LP-17 core, or a 32 bit core? What is the midi controller supposed to do? How do the 3 keyboards you already have enter the mix. Need some help. John W. Couvillon
  3. Johannus OP240., Have you constructed the control surface? Take a look at the writeup for the midio128V3. it specifically covers the analog programming using the AIN module and others and how to program it. Johnc
  4. Johannus OP240. If you are discussing mios8 and midio128, you are in the digital domain, not analog. What are you attempting to do? If you go to the Ucaps website, and go to the link for MIOS8 located in left panel, you will find some apps down at the bottom of the list dealing with J5. johnc
  5. Pharline, I think you best bet to use the reed relay approach that is described on the midibox website. That way you will get the o imped. connection. johnc
  6. Tom, If the organ is to remain intact and fully playable, then all existing relay functions must remain. Adding midi in and out means: The existing organ relay would have to be modified to accept a midi input stream, and also generate a midi output stream. Accomplishing that brings up many questions, and could be done by several methods, i.e. a. Modify electronically the existing relay to accept the midi in and out, which could be difficult or impossible depending on the design of the relay. b. overlay, mechanically, the key contacts, stop action switch contacts, pistons, swell
  7. Hello TOM, You are embarking on a project that has been explained in depth many times on this forum. Your statement, " Goal is to have MIDI IN and OUT for a church pipe organ (2-61 note keyboards + 32 note pedals + Stop Action switches)" is sort of open ended, allowing a variety of outcomes. In order to have a better understanding of your Goal, a few questions> 1. As stated, the instrument is a pipe organ, "pipe" being the key word, and its a two manual instrument with pedals and "stop action switches". > How many ranks? > Will the midification replace the existing o
  8. Phatline, Can you elaborate on your electronic organ; type, electronic encoders, etc. when you say "midificate" thats not quite enough for objective understanding. some interpretations could be: 1. you strip out all existing internal electronics and install key switch encoders DINs, a midibox core device (core 8, Lpc17, etc.) runnning midio128 or other. using a pc for relay operations. 2. You only want to force the existing organ to play by, in effect, forcing keys down electrically rather then by finger. I assume "kepresses on ground level" means the contact actuated by the keypress is
  9. My interest is up in the area of driving stepper motors for CNC projects, etc. Stepper motors can be driven with Arduino, RasbPi, etc using a uln2803 quite easily, so can't see why a core 8 couldn't be used as well. What existing app for the core8 would best be adapted for this application? midio128 V2? Does anyone have experience in this area, and is willing to share? Johnc
  10. TK, No, you are not lost. I was not aware that the behavior of the status LED had changed with ver. V3.019. That explains the situatiion most adequately. Thanks, johnc
  11. I hope that I explained the situation commpletely. The LED has always blinked and stayed on especially when first energized, but it has never been this bright and pulsing on and off. This behavior began when i plugged in the USB cable to use mios studio. The LPC has been operating along time with a core 8 on a common power supply, so the jumper isolating the system from usb/computer power was removed. since the incident, returning to USB power with the jumper in place does not solve the problem. Also, the reason I was using mios studio was to load the recorder/player fix that you (TK) p
  12. The red LED on the LPC pcb is cycling on and off, slowly building up to bright, then fades away. the LED cycles much like the led on a USB flash drive. The LED is much brighter then normal at its brightest The LPC has midio128ver3 loaded and appears to be functioning normally, with exception of the LED. This began when a USB cable was plugged into the USB connector on the pcb to view the DI settings with mios studio. The unit was energized, receiving power from a 6vdc supply (J1), and the jumper on the PCB (J22)was removed to isolate from the USB power source. The usb cable was removed,
  13. Pete, I plan to use a 3/16" panel, and yu read my mind. The SD reader will mount on a wood block glued to the back of the panel. When the sd card is in the reader, about 1/4" sticks out, so it should fit perfectly. The pushbuttons, LCD and encoder switch will also be on the panel. Thanks for the input. johnc
  14. Hi Pete, Thanks for the input. Google brought up several sources. The style I am looking for is of the type sold by ESS, http://www.esskabel.de/upload/files/pdf/ADA-SDCARD-USB_EN.pdf. Only problem is that it adapts to USB. There is also one similar to the sparkfun unit available from Parallex, but has no angle bracket to mount the PCB at 90 deg. to the face of the vertical wood surface. Johnc
  15. Anyone, I want to build the control midio128 V3 control surface into the face of my organ console with a card reader mounted behind a slot in the wood surface for insertion of the SD card. Does anyone know of a source for same? Thanks, Johnc
  16. TK, Great! I assume the all I have to do is set up my PC, run mios studio, and load and transfer the hex file to the LPC, and I am good to go! Thanks Thorsten, and you too, Pete! Johnc
  17. Hardware: A 3 manual midified organ console , with (64) SAMS, 42 pistons, (2) swell shoes, (1) cresendo pedal. Relay components: One (1) LPC17 One (1) Core8 w/ 3 DINS (DIN inputs are pedal (32 notes, channel 4); pistons, contacts on 18 SAMS, Contacts on Rotary Swell Shoe drum controller all on channel 15) . Two (2) KB modules - encoding three keyboards(61 keys each, channels 1,2,3) , and contacts on 64 SAMS on channel 5. Config .MIO defines output on matrices as midi OUT2. Core8 messages route IN1 to OUT2. Modi Router OUT2 feeds Artisan sound Engine. There are no other connect
  18. Pete, I posted a note to TK in the midio128 ver3 thread referring to this thread regarding the recorder/player. i never know where to put my posts. Hopefully TK will find that post, or this one and respond. He seems to keep up with whats going on. In the past, you gave me some help with issues regarding DOUTs especially when UL2803 drivers were emplanted on the DOUT pcbs. Also grounding and power supply issues with the LPC and DOUTS. You may have notices that the block diagram i posted earlier on this thread was devoid of the Driver chain of DOUTS and all discussions of SAMS. Following t
  19. TK, Please take a look at posts (John's organ midification)concerning recorder/player issue involving keyboard inputs from 8x8 matrices. Kpete has been assisting and suspects a problem with the recorder. Thanks, johnc PS: should this post be in this thread, or someplace else?
  20. Pete, 1. I sat on the bench, set the stops I want to use, played a bit. all good. 2. using the control surface, I started the recording, noted the time incrementing on the right end of the LCD, The "recording" was blinking. 3. Went back to the bench and the keyboards are dead, nothing, no sound at all. I have the dig I/O with both play and record checked, and the same for midi1 and midi 2. What does the ****ALL DOUTs DEACTIVATED**** mean. If the DOUT pins are deactivated, the matricies won't encode. How is this changed? Should I wait until after the LPC is in record mode to set the
  21. Pete, Thanks for the patience with my questions. My understanding of how the player works is improving, but not the why! At this point, I would have to ask - How do I get the player to record the keyboard and SAM sensor data as well as the stuff coming from the core 8 thru the router at the same time? I am suspecting that what enters a router midi in port and exits a router midi out port, is basically not seen by the LPC. Therefore, if i did away with the core8, and tied the DINs to the J2 on the last KB pcb, then the player would record everything. Yes? I would need at least the pedal
  22. Hi Pete, Thanks for the input. Does selecting midi2 mean that the recorder will record the midi out2 port on the router,and play the midi in2 port on the router. I went through the process as you described but still got nothing. Notice on the diagram I attached that all midi messages from the console are routed through midi out2 to the soundengine. Midi in2 is not used. All midi messages from the core 8 (pedal,pistons, couplers, swell shoes) is routed to midi in2 and out midi out2. Johnc
  23. Kpete, you have some posts dealing with the recorder/player on midio128 V3, and seem to be up on the player. Is there some special setup as regards the router in the LPC-17 and midio128 v3/ As you may recall, i am usng 2 KB modules with 4, 8x8 matices for 3 KB's, & SAM contacts, and an additional line with one core9 and DINS for pedal and pistons. The organ operates without a computer attached on the front end, no jOrgan, miditzer, etc. using the router, all midi out messages go out on "out2" to an artisan soundengine. each of the matrices specify midiout on out2; the midiout on t
  24. Mumblecake, I didn't mention, but i am using two KB modules with the LPC17 for 3 KB's and SAM sense contacts. I started out with a 16x16 matrix, but the simplicity od the KB's in conjunction with the LPC17 changed my mind. I also built the SAMS sense matrix by putting the diodes directly on the SAM, and building the matrix with jumpers, resolving to 2 8/c ribbon cable to the KB module. Probably a big antenna, right. Live and learn! while having the spontaneous action, i did a wiring consolidation, separating the wiring from the douts to the SAMS from the wiring for the sense matrix to
  25. Is the NG a functional replacement for midio128 ver.3?
