  1. Troubleshooting midiphy SEQ v4+

    Ha, you're right, the +5V plane is connected on this revision. Don't worry, we'll sort you out with a replacement. Peter will be in touch.

    Please check the locations I mentioned and post a photo of your soldering. Don't worry, the pours are not connected otherwise nobody's board would work...

    Can you post a picture of the soldering? The most likely place is on either of the two USB connectors. This is the bottom of the board with the +5V and 0V connections highlighted.
  4. MB6582 PIC troubleshooting

    RME Fireface should work. You can also change IDs through MIDI:   Select the ID in MIOS Studio as follows:    
  5. Adding Faders to MBSeqv4

    I'm not sure if CC is implemented for note steps. The encoders are also responsible for the UI in general. It would also be a lot of data to poll/update.  But yes, _NG with AINSER would be the right direction. You can also get high-speed UART by removing the optocouplers. The connection is more fragile of course.
  6. MB6582 PIC troubleshooting

    Sometimes you forget to socket the optocouplers, or they are faulty somehow.  Could be an incompatible MIDI interface (is it on the blacklist?). Are you aware of the different device IDs for the PICs? They need to be configured in MIOS Studio.

    Maybe we should have a new thread for module things? Regarding depth, note that it would be doable to squeeze things tighter with shorter headers or even direct soldering. Right-angled IDC headers would also help. For panel files, at least at the beginning I prefer to keep them closed. We might offer different colours in the future (e.g. black panels). But if you really would like to do your own, just put a note in when you order and I can give you the dimensions. It wouldn't be difficult to measure either :).  
  8. One MB-6582, One Power Supply: a Tutorial

    I noticed the same thing: the switch action removed the 0V rather than +V. It can be confusing when the MB-6582 "receives" 0V from somewhere else. From memory, it would not be so significant if the bridge rectifier was still there.

    If the MAX525 chips are SSOP, then you could substitute them. If they're DIP, then it won't work. I use an LED driver to indicate CV activity. You would probably exceed the current limits of an op amp plus run into loading issues just placing them in parallel.

    @lukas412 looking great! We are indebted to Adrian for his awesome work on the case @knochenfabrik I figured, but thanks for the clarification. When the rack ears are ready it should work to mount directly that way, but nicely done with the hack/workaround!
  11. midiphy SEQ v4+

    Indeed! The line drivers would actually "buffer" the SRIO a bit, but as long as the cables are short it should still be okay. The other option of using line drivers (if required) is to omit the DB-25 connector and use the IDC instead. The ribbons would take less room.
  12. midiphy SEQ v4+

    Well that's an awesome photo! Presumably you had to remove the rails/threaded inserts? But sure, everything should fit in 3U. There's been promise of ears for 19" rack mounting for a while but those are still on the way. Not long until the modules are ready. But summer holidays can result in a slowdown sometimes. Btw. with everything in the case like this, probably you wouldn't need to use the line drivers at all. Just connect J8/9 and J19 to the respective digital and analogue expanders.

    Or TME?

    I would recommend Reichelt but check the shipping price to France. Otherwise, just order (I think) 60€ worth of parts and the shipping will be covered from Mouser.
