  2. midiphy SEQ v4+

    Posted

    Hello,

    After a few mistakes, I finally finished my build of my Seq V4+

    Thank you to Peter/Hawkeye from Midiphy, Michael Menze, and Andy/Latigid On.

    It’s working great and I’m finding it very intuitive to work with, though I’ve only just scratched the surface.

    All the best, 

    Jeremy

  5. Troubleshooting midiphy SEQ v4+

    Hello,

    I got to the stage where the firmware was supposed to be uploaded.

    All tests (switches, buttons, LEDs) passed perfectly. 

    Unfortunately, I think I uploaded the wrong firmware and "bricked" the core board - I can't seem to communicate with it via MIOS Studio.

    2 questions:

    1. If it is in fact bricked, how can I fix it?

    2. When I do fix it, can someone link to the firmware for the RH MIDIbox SEQ V4?

    I've uploaded a picture showing the message from MIOS - the SEQ V4 has no lights, only the green light on the back pulses momentarily when I plug in power.

    Hello,

    I'm having some trouble with video 2, step 33, 'Building and testing JA Matrix LED cable'.

    MIDI CC 16 does move the LED dots, but some of them seem to be missing.

    Ive attached a picture - what are the likely culprits here? The matrix itself, the cable, or the shift registers?

    All the best, Jeremy

    Thank you - the bodge option makes sense (jumper wires could do it), and I will probably crack on with building the lemec boards.

    One thing I am still confused about is the SEQ_L.NGC situation - I get only 2 MIDI ports (In and out) and no specific NG ports.

    load seq_l works though, and I repeated the video many times and I'm not sure what I could have done wrong - the script is on the SD card and installed the hex file from MIOS studio successfully.

    Thank you both for looking into this.

    I've had a look at all my joints, but still no luck. I can look at alternative solder - I also have a flux pen if you would recommend that.

    As far as SW 12 goes, unfortunately I think the copper pad is worn out, so it looks like I may have to order another JA PCB + parts and have another go.

    Still, it would be good to figure out what went wrong here so I can avoid it next time.

    I have installed SEQ_L.NGC, and succesfully loaded seq_l and set debug on.

    One thing I noticed however is that 'NG' doesn't show up as a MIDI port in MIOS as it does in the build video. Could this indicate an issue? I'm not sure why it's occurring as I am following the instructions in the video and can successful load seq_l...

    LEDs definitely don't have reverse polarity, I checked again, and I was very careful of this in the first place.

    As far as the physical issues you mention, the one which I suspect the most is a dodgy ribbon cable - could it be possible that this could prevent the LEDs from lighting up, yet still allow the switches to function?

    Hello - now I am testing the JA PCB and having 2 problems:

    1. All switches show activity in MIOS Studio except for SW 12, which gives no response.

    2. None of my LEDs light up when the switch is pressed.

    I triple checked LED polarity, part numbers, IC orientation and reflowed everything - still no luck.

    Any idea what to look for next?

    All the best,

    Jeremy

    Thank you very much - cutting them off with some flush cutters and pumping away the solder eventually worked!

    I have connected the USB board up to the computer and confirmed that MIOS Studio can communicate with the board. 

    Are there any other tests I should run to ensure that I haven't damaged the USB board in the process through heat, or is it safe to say it's fine?

    Hello,

    I am in the middle of building my Midiphy SEQ v4+ and things are going well for the most part.

    Unfortunately, I realise that I made a mistake in assembling the USB PCB.

    I seem to not to have properly put the metal parts that screw into the case so that they are flush with the PCB - instead, they stick up about 3mm.

    I have tried to desolder using a wick/pump but no luck - they are solidly in there.

    Everything works on the USB PCB and I'm able to upload the firmware to the core, but I'm aware I will now have a problem when assembling the case of my Seq V4+

    Any ideas, or will I have to buy and reassemble the PCB?

     

     

  18. Midibox Seq v4+ Black Buttons

    in MIDIbox SEQ

    Posted

    Hello everyone,

    I'm going to get started building my Midibox Seq V4+ very soon.

    I am building the Midiphy kit.

    I read in another forum post that some users are installing black buttons, which I've seen in some of the pictures.

    The post I am referring to suggests an alternative button/button cap here:

    Questions:

    Is this arrangement (5GTH920+1LS096-15.0 instead of 3FTH9+1S11-16.0) still valid with the current PCBs?

    Are there any funtional reasons not to make this substitution, or is it an aesthetic choice only?

    Best regards,

    Jeremy
