Thank you very much for your patience Cimo. The button program worked. It was very nice to see them light up. Current status: A. I have now reloaded MB64, and realize that what I have connected to pins 9-16 on the DIN corresponds to LED's connected to pins 1-8 on DOUT. B. In MB64, the LED's only flash as the button is pressed and then go out again. I assume that (A) is because of definition in the setup_midibox64.asm file. Is (B) the LED's not toggling also a function of the setup file? Thanks, John

Thanks Cimo, All unused AIN's are tied to VSS. And yes, it is: SI on J9 that is at 5V SO on J8 is 4.4V

Thanks Cimo, The AIN's look okay. With DOUT SO disconnected, Core J8 SO reads 4.44 VDC, but J9 SO reads 5.0 VDC. Is this a problem with the core?

Okay, I have spent many hours trying to understand this now, and the leds are not lighting up. :'( In my MB64 v2 I have only one DIN and one DOUT module connected. I am using MIOS V1.9F. The buttons are working fine. My DOUT board is an R2 from Smash. If my understanding is correct from the posts I have looked at (many times) the default would be for when the button toggles, to turn the led on or off, right? Do I need to have all 8 SR's (both DIN's & DOUT's) connected? I checked the output pins on the header of the DOUT board and I cannot find any voltage on any of the outputs regardless of the button state. I have never programmed anything, so the asm files are perplexing. :-\ Any guidance or ideas would be of great help. Thanks, John

I have two dout boards connected to the core. How are they addressed? If I want to trigger an led with an incoming midi event, how do I tell it which led to illuminate? Please be patient with me. I cannot believe how little understanding I have of this. :) Thanks, John

Hi All, I left out the jumpers from the 4051outputs to J5 on the AIN cards. Faders are working, ashes are burning :) C ya John

Thanks Cimo Seems like I had them all grounded. I removed the three wires from J6 grounded all the pins except +5, ground, and tied one fader to the input. It worked! Cool..., okay, I will try to get just one 4051 working now. I also noticed that the response was reversed, I guess I have my +5 and ground swapped to the fader.

Hi All, I have a 18F452 that came with V1.9F MIOS. I loaded setup_midibox64.hex file from midibox64_v@_4b. Let me qualify that I am a complete idiot regarding midi. I have never used it for anything, but I am hoping to use it to control my yamaha dsp2416 cards and Sonar. My core is attached to to AIN boards. I have one AIN wired to 8 faders. All other inputs to the 4051 chips are tied to ground. I loaded MidiOX and yokes. When I use midiox to connect my mpu-401 to midiyoke-1 and then use midiyoke-1 to control items in the software, the sofwarefader will just tremble, and not respond to fader movements. When using midiox to monitor the mpu-401 input, messages are blazing, constantly scrolling. Being new to midi, I don't know if there is a constant interogation of midibox parameters and therefore a constant stream of data? Or, should there be no data sent until I move a fader. I must say I wish I had never started this project so long ago. I put it away, and moved across the country, cry, blah, whine, blah... But, instead of pitching the whole mess, I would like to make it work. Any advice is greatly appreciated. Thanks, John :P

Thanks, All I've ordered 5 from Mouser. I Appreciate the help. John

Thanks Stryd, Are there many defective optocouplers, or is it possible I damaged it? John

Thank you Thorsten. I performed TEST IN7 on optocoupler. switch open/cable not connected = 5V switch closed/cable connected = 2V This means 6N138 is defective? John

Well, you all amaze me. I started with such high hopes more than a few years ago on a MBHP 64 project, then put it away as I got busy with other things. I feel technically inept. I thought that I should complete the box for better or worse, so I determined to make the box work (this might be my mistake). I am using a Smash TV board, pic, and components that I purchased 3.5 years ago. The pic is labeled MIOS_BOOTSTRAP_v1_1B All 0's underneath. I have attempted to use MIOS Studio to upload: update_without_installed_mios.hex When I start the upload with: Device id 0 "Wait for upload request before starting upload" checked and Smart mode I receive the following message: Starting upload of update_without_installed_mios.hex Hex file contains code in MIOS range, forcing reboot! Received Upload Request Sending block 00000000-000000FF Error: Received unexpected Upload Request (Sending block and Error repeated until abort) I tried the following from the midi troubleshooting guide: TEST IN1: Ok TEST IN2: Ok TEST IN3: LED stays lit (even with no message coming in?) TEST IN5: Ok TEST IN6: LED stays lit regardless of switch position Thank you for any help in advance. I should have just stuck to playing guitar. :P John Gregory :

Wow Justin, You have made things much more clear for me. I plan on using the minimal 2 x 16 lcd to begin with. I figure I can get more elaborate as I figure a few things out. Also, thanks for your advice on getting the core going first, then adding a bit at a time. John

Hello all, :) I found this site a couple of years ago, and was blown away. Here and there as time permits, I have laid out a design, as I have found components at the local surplus store. I have designed a straightfoward setup with 17 faders, 60 some momentary switches, nearly the same amount of leds, 48 10k pots, and one encoder I scavenged off of an old Panasonic proffesional VCR. I am having no problem soldering this mess together and hooking it up, and am nearing completion. How does the MIOS work? I have never used midi before, other than an old alesis effects unit that I controlled with a footswich. :) I am going to use my midi-box to interface with a software called C-Console that I use to route audio on a yamaha dsp2416 card, as well as Cakewalk Sonar, that I use to record audio with. both of these apps can learn the moves from a midi device. How does MIOS help me to interface the midi-box with this stuff? Do I just load the MIOS into the computer, and it recognizes the midi-box? Is there a gui interface that I work with to make it go? Thanks for your input, I feel a lot of anxiety with the box coming together, and me wanting to hook this stuff up, and I don't have a basic understanding of how this stuff works. John Gregory

Very Cool Count me in please!! John
