  1. Troubleshooting midiphy SEQ v4+

    Hi, These encoders should be decent, so I wouldn't think the encoder had gone bad. Rather, there might be an interconnection issue. The 9th encoder is connected to pins 4 and 5 of J1, so check that you get good contact there. If the pins don't reach far enough into the through-board header you might get an intermittent contact. Check all solder points too as you might have a dry joint etc. Best, Andy
  2. Sorry, didn't see your message as the notification settings were broken for a while. I can't say anything about Hauptwerk but you should be able to monitor debug events in MIOS Studio. I would try to diagnose the DIN/DOUT functions and matrices first at the hardware level. 
  3. Event_Sender, send all

    I'm no NG expert, but what is the exact event/ the parameters used? Do you set specific ports for example? Maybe post the config and somebody could help.
  4. Troubleshooting midiphy SEQ v4+

    Many thanks for reporting and I'm glad it works! Is the hub also connected to the computer and sending data that way? There is an OTG startup sequence where the devices have to decide who's the boss. Maybe things don't make it that far if there's too much going on with the datalines. Just speculation!

    Sorry, I managed to upload one twice. The quell PCB functions as a terminator, so you clamp unused inputs to 0V.

    I recently designed Eurorack versions of DIN and AIN, still need to test but hopefully in the next few weeks,   @Antichambre maybe you should start your own thread as to not mix up things, thanks. Have fun! Andy

    Not sure I understand fully. You adjust the trim pot to get the scaling as linear as possible, i.e. the trimmer should be set so each octave step is as close as possible to the target voltage. Then you use the SEQ encoders to finely adjust for each volt setting. The DAC can't drive negative bits, so there is a limit to the lowest setting. But the remaining octaves should be very linear. Did you already see @Hawkeye's video on the calibration procedure?

    Sounds like it could be a software bug, in which case the following thread is the place for it:

    One other idea: you could try plugging directly into the 407v board (mini USB cable). Here is the schematic, maybe some of the jumpers are helpful?  
  15. Out-of-stock parts for midiphy BOM tool

    Some Mouser parts have longer lead times at the moment. Here's a few suggestions: 595-SN74HC595DR -> 595-SN74HC595D (just non-reel packaging) 490-SJ1-3535NG -> 490-SJ1-3535NG-BE (blue) 594-K104K15X7RF53L2 -> 75-1C10X7R104K050R 806-KCDX-5S-S2 -> reichelt Conrad CR1206-JW-331ELF SMD resistors just use a 220R or 71-CRCW1206330RJNEAC WP154A4SUREQBFZGW Kingbright LED, tricky to find a frosted one, but basically any generic CC RGB LED will do, or a bicolour 3-pin is fine but normally not available in "nice" green. *** Feel free to post your suggestions or if you can't find a part.
