  1. RTP MIDI System

    In my studio I've had a similar problem, but I am not keen on leaving the traditional MIDI 5pin realm - I can live with physical MIDI routing (and merging), and I don't require the central point of the matrix to be a PC or Mac. All of my synths, effects and other equipment still have 5pin DIN connectors. Around four years ago I came up with the MIDIbox Matrix, a proof of concept that does MIDI routing on an FPGA. In the meantime and with the help of a few people the project has evolved into something that has 64 MIDI in ports and 64 MIDI out ports, that allows merging, and that can be controlled by a piece of java software from the PC (or by a dedicated MIDIbox control UI). The main concepts of modularity and scalability have remained, though, so that the system can be extended in groups of 4 I/O ports that sit in a break out box (BOB). I guess I should really update the documentation to reflect the current state...
  2. I still have some PICs from the olden days and can flash them, but located in Germany. Shoot me a PM if you want to go that route.

    Connecting the upper red LED to this one did not help - it was still not lighting up in the fluxtest. Replacing the LED helped, BUT: after unsoldering it, outside of the circuit, all three colors of the presumably faulty LED light up, and with the expected brightness. I'm dead sure this was not a soldering issue. Question: what was it then?  
  5. Hallo zusammen, wie die meisten hier wahrscheinlich wissen, bediene ich immer wieder Anfragen von MIDIboxern weltweit nach TPD- oder BLM16x4-Platinen. Leider hat die Deutsche Post zum 1.1.2019 die AGBs geändert und erlaubt Privatkunden (und nur diesen!) nicht mehr, im Brief International auch andere Dinge als Dokumente zu verschicken. Damit haben sich die Versandkosten z.B. für eine TPD-Platine von 1,50€ auf mindestens 16,00€ (Päckchen International) vervielfacht und stehen in keinem Verhältnis mehr zum "Warenwert". Ich habe gerade die Petition 'Einführung der Versandart Warensendung International für PrivatkundInnen' unterschrieben und würde mich sehr freuen, wenn ihr auch mitmacht. Je mehr Menschen die Petition unterstützen, desto größer ist die Wahrscheinlichkeit, dass sie Erfolg hat. Hier könnt ihr mehr über die Kampagne erfahren und unterzeichnen: https://weact.campact.de/petitions/einfuhrung-der-versandart-warensendung-international-fur-privatkundinnen Viele Grüße, ilmenator

    Here you have a photo (or two). In the upper one, the culprit is in the second Mathias row, the sixth from the right (third from left) Ok let's say I do this and it works, what does that tell me? In order to being able to do my own thinking as well, the schematics would be really helpful. Are these available somewhere? Thanks, ilmenator

    I have a problem with the superflux LEDs, more precisely with the 6th LED of the second row (on the smaller board). I am on the red/blue color scheme. The fluxtest does not light up the red LED on the mentioned superflux LED, but everything else works. The LED itself is working, though - when I separate it from the circuit and test it with the multimeter, all three colors work, also red. Where is this specific LED connected to? Should I search for a short circuit somewhere?

    Success, no more jittering and the encoder seems to behave normally. Thanks for the quick reply!

    Yeah, I've lost pads 10 and 11. 10 probably doesn't matter because it seems as if it was solitary with no connection leading towards it, but 11 seems to be the one going to the via hole next to it. Where does this connect to? I will run a thin wire there...
  11. midiphy SEQ v4+

    I was thinking of clipping the legs carefully one by one and then removing them as I proceed - has anybody tried this before?
  12. midiphy SEQ v4+

    Thanks Andy, that was the hint I needed. Looks like my "client" ordered the wrong parts - maybe he used an old(er) BOM version? Just a guess, I'm not going to check this further. Now let's get creative with the removal of the bad boy...

    Having a problem with the JA board here, which seems to act like an antenna. I get lots of MIDI messages in MIOS Studio when doing the MBNG check, and LEDs randomly flash. When coming closer with my hand and when turning the PCB in my hand, random activity shows.

I can trace RC, SC, SO, SI lines from ICs to the header ok, as well as +5V and GND. Where should I look next? A set of schematics would come in handy now!  
  14. That's true, my bad! The mixup happens when soldering the connector to the wrong side of the PCB.
  15. Sure you can, you have crimped the connector to the cable the wrong way round. There is a little marking in the form of a triangle on the connector - this should match the red wire, as it marks pin 1. It looks as if you have ignored this. That's what I already suggested above.
