  1. Troubleshooting midiphy SEQ v4+

    Number 8 perhaps? :D Though I think I have to get the beat LED installed to get the official stamp! How much clearance should I leave to fit your LED diffuser?  Thanks again everyone! If anyone has similar problems to the ones I faced I'll be happy to share my experience. :D
  2. Troubleshooting midiphy SEQ v4+

    You rock!  Had a few more hurdles to get over (bad I2C cable) but it's alive! Still have a couple things to finish before calling it complete - beat LED and I ran out of 10 pin connectors for the LineTX cable from LeMEC_R, but it's looking good! Thank you Andy, Peter, Bruno and the rest of the midibox community for all your patience, wisdom, and troubleshooting help! Thank you TK and Adrian for your efforts on this project as well! Can't wait to learn the ins and outs! 
  3. Troubleshooting midiphy SEQ v4+

    :D Got all the MEC switches/LEDs installed and working correctly now! Having a strange issue with the Matias switch LEDs - all the buttons and encoders on both boards are still working. I initially had a few red LEDs that weren't working, I've replaced those with the spares and they're great now, red lights are all good on both boards. Blue lights working great on LeMEC_R. On my LeMEC_L (I've got the right board this time ) every 4th blue LED isn't appearing. Top row missing #4 and #8, bottom row missing #4 and #8. I did replace the #4 bottom row LED to get the red working again but the blue problem still happens. Picture of the board: https://imgur.com/a/39nPcFc

    Good news: I've figured it out! Ugh this will teach me not to work on projects until 2am! I had the LeMEC boards in the wrong order.  Everything is working great now. So sorry for wasting your time Peter and Andy! Though I think some good troubleshooting steps came out of it nonetheless.
  5. Troubleshooting midiphy SEQ v4+

    Hah I'm an idiot and just realized % is the MIOS comment character! I was wondering what %turns was referencing.  Testing the LeMEC_R - it seems to be booting up with the dout pins enabled and doesn't seem to react if I manually set the value to 0. Both buttons and encoders all fully function. The core has NG loaded but behaves this way with and without the sd card loaded. Is that suspicious?   Edit: For the next person that does this - YES this is suspicious, doing the above test on the second board caused lights to turn on on the JA board. If you have the boards in the correct order this should not happen!
  6. Troubleshooting midiphy SEQ v4+

    Whoops, forgot I have to right click to copy the terminal data instead of using Ctrl+C! Here's the actual input: [1240259.981] set dout 0 1 %turns first output on [1240260.142] DOUT Pin 0 (SR#1.D7) set to 1 [1240383.356] set dout 0 0 %turns first output off [1240383.517] DOUT Pin 0 (SR#1.D7) set to 0 [1240401.956] set dout 7 1 %turns eigth output on [1240402.117] DOUT Pin 7 (SR#1.D0) set to 1
  7. Troubleshooting midiphy SEQ v4+

    Yep I'm beginning to think the same! I ran the following (minor correction to use 0 instead of d0, MIOS didn't like the d): [1240259.981] set dout 0 1 %turns first output on [1240260.142] DOUT Pin 0 (SR#1.D7) set to 1 Tested the encoders again with no luck. Then reset to d0=0: [1240259.981] set dout 0 1 %turns first output on [1240260.142] DOUT Pin 0 (SR#1.D7) set to 1 Then enabled d7: [1240259.981] set dout 0 1 %turns first output on [1240260.142] DOUT Pin 0 (SR#1.D7) set to 1 Tested the matias switches with no luck. I tried once immediately after booting up, and once after loading seq_l. Same results both times. I'll remove the IC and get another one ordered. Thanks again!
  8. Troubleshooting midiphy SEQ v4+

    Definitely looks like something is up around IC2 Pins 15, 1-7 (QA-QH): 0v (pins 3-5 seem to occasional show .001v) Pin 9 (QH*):.422v Pin 10 (SCL): 4.8v Pin 11 (SCK): 2.7v Pin 12 (RCK): 4.8v Pin 8 & 13 (GND): 0v Pin 14 (SER): .46v Pin 16: 4.8v On the working LeMEC_R: Pins 15, 1-7 (QA-QH): .586v, Pin 9 (QH*): .493v Pin 10 (SCL): 4.8v Pin 11 (SCK): 2.7v Pin 12 (RCK): 4.8v Pin 8 & 13 (GND): 0v Pin 14 (SER): .422v Pin 16: 4.8v I reflowed the resistors around IC2 just to make sure the top soldering wasn't bad and confirmed the resistor networks are in correctly they're the same part and orientation between both boards. Also checked all the 4148 diodes and the voltage seems good (4.8v everywhere).
  9. Troubleshooting midiphy SEQ v4+

    @latigid on thanks that definitely gives me a better understanding of how the button matrix is working. I'll try tacking down the cc pin of the superfluxes tonight.  All of the encoders seem to be working fine, I can see the CC values increment and decrement correctly in MIOS Studio. As much as troubleshooting can be frustrating it definitely helps teach me about circuit design! Appreciate the hand holding. 
  10. Troubleshooting midiphy SEQ v4+

    I went through and reflowed all the IC and transistor/diode pins, double checked with a magnifying glass but still no luck with the buttons. I'm admittedly a bit weak when it comes to digital circuits, would it make sense to look at the IC that joins the serial data from LeMEC L and LeMEC R or is the problem likely before the LeMEC L data gets that far? Is the button design similar to the original seqv4? I was looking in other threads to see if I could find someone else that's had similar problems.
  11. Troubleshooting midiphy SEQ v4+

    Thanks Peter, I did an inspection with a magnifying glass tonight and it looked ok, but I'll run over them all with the iron tomorrow to see if that clears things up. 
  12. Troubleshooting midiphy SEQ v4+

    Good news, got the encoder working! I had a cold joint on IC5, the pad looked wet but the leg of the IC hadn't actually gotten any solder on it. Still stuck on the buttons on LeMEC L, the transistors are all the same type from what I can see (marked with 6G) and the BAT54s (marked with 5A). Is there a specific IC that handles the button presses for the whole LeMEC board? It's odd that it all works on the LeMEC R but none of the buttons function on the LeMEC L.
  13. Troubleshooting midiphy SEQ v4+

    Back at work so I'll have to follow up on the testing this evening - but for testing I had everything chained JA->lemec_L->lemec_R. Thanks for the quick responses!
  14. Troubleshooting midiphy SEQ v4+

    I inspected the two LeMEC boards and can't spot any shorts between the pins, I did trim the pins on the outside edges to avoid shorting against the header. I also tried swapping the two SEQ_PLATE pcbs to see if it was a problem with the plate board but the behavior was the same so we should be able to rule those out. Still having errors uploading directly to the forum, so they're uploaded to an imgur album again: https://imgur.com/a/naVxaRL Thanks for the help!
  15. Troubleshooting midiphy SEQ v4+

    Hah yes it's too true, I think I'd been skipping around the build videos so much I'd missed that you had restarted MIOS Studio to get the board showing up. I do actually have an macbook pro for work but it's a new one with the damn USB-C ports and I have yet to get an adapter.  I got the JA board up and running this morning, all the buttons and encoder seem functional! The LeMEC boards are a different story: On the left LeMEC board it seems like all the buttons (encoder press and matias switches) don't register, turning encoders left and right behaves correctly. On the right LeMEC board all of the buttons seem to work as expected, turning encoders works on all encoders except on encoder 16. I haven't had a chance to dig into troubleshooting as I had to run to work, but if anyone has a guess as to why all the buttons aren't working on LeMEC_L I can focus my hunt at lunch/this evening. I'll update with pictures as soon as I'm able. Thanks again!
  16. Troubleshooting midiphy SEQ v4+

    Wow - kicking myself here. Simply restarting MIOS Studio brought it back to life! I was able to get the core showing again and uploaded the MIDIBox NG app as well, though I did need to restart MIOS Studio again for it to show (running on Windows 10). Appreciate the super fast responses! Thanks for helping with the pictures ilmenator, not sure why I kept receiving -200 errors during file upload.
  17. Troubleshooting midiphy SEQ v4+

    Hmm scratching my head a bit here - over the weekend I reconnected the USB pcb and core pcb and was able to upload the seq v4 project.hex file successfully. I just finished the JA pcb and went to upload the ng_v1_036 project.hex file for testing, but MIOS studio doesn't seem to recognize my core at all. MIOS Studio does see MIDI IN/MIDI OUT named MIDIBox SEQ V4+ (and the other 3 seq channels), but no response from the core. Troubleshooting steps so far: Removed SD card PCB from core. Inspected the pcbs for shorts but don't see any. I reflowed a few joints just to be sure.Inspected 10 pin cable connecting the USB pcb and core pcb but it looked good. Tried changing the device ID in MIOS Studio Tried unplugging RME audio interface to remove other MIDI devices STM has the three bottom jumpers removed, power from 5v, and BOOT CONFIG set to FLASH, the other three jumpers are still in place. I looked through the MIDI troubleshooting guide but it seemed to be more focused on PIC troubleshooting, if I missed something apologies!

    Just wanted to send some quick praise for the full kit packaging, amazing job with the labeling! The case looks fantastic! Everything is going together great so far, finished everything except the two LeMEC boards, should hopefully have it all working in the next few days!
  19. midiphy SEQ v4+

    @Hawkeye and here I was hoping synth DIY was somewhere I didn't have to worry about Trump! Very likely the case!   Thanks for the update! 
  20. midiphy SEQ v4+

    I know a watched mailbox never boils, but just wondering if any US based midiboxers have received their essential kits yet? (In reality I'm hoping tracking updates just after I post this.)
  21. midiphy SEQ v4+

    Times I wish I lived closer to Germany - jealous! Enjoy the adventure!  My mini-victory: Just received my reflow station in the mail!
  22. Out-of-stock parts for midiphy BOM tool

    The LED is available at Digikey: https://www.digikey.com/products/en?keywords=WP154A4SUREQBFZGW   For the capacitor I think any 50v .1uF X7R 1206 10% should be fine, but I'll let the powers that be give a definitive answer. :)
  23. midiphy SEQ v4+

    Woohoo! Christmas comes early! Really excited to get this build going! Thanks for all the team’s hard work!
