  2. Displays not initializing after working for a while

    in MIDIbox SEQ

    The LCDs expect an "enabled" signal, so I wonder if it's a problem having only one connected.

    Load up something easy such as MB_NG and see if it works.
    Reflow the joints on the 595 socket (chip out first). You could have some cold joints; ideally they should not "bulge" around the PTH pad. 
    What is the scratch between J15A/B headers on the solder side?

  5. MIDIbox SEQ new frontpanel idea

    As a newcomer, this looks like an awesome update. Any chance the overall height will be slightly smaller that the previous version? The v4 is barely to tall to fit behind a euro panel.

    Not for this iteration, the height of everything is about 124mm. But a Eurorack-mounted version would take up ~84HP and consume a lot of your +5V rail. The limiting factor here is the OLEDs. If there were smaller displays, the whole thing could be more compact.

  12. Connecting Analog Outs to Modular safely

    The AOUT boards have an op amp with no output resistor. Every time you plug into a socket, the tip shorts to 0V. But TL074s are fine with this (they do heat up though!).

    Some people will say the the typical output resistor isn't needed anyway and it leads to pitch errors. There are also fancier output schemes with the limiting resistor in the feedback loop.

  16. Help needed connecting WIlba CS

    Please embed the pictures here so when the offsite doku goes bad they'll last at least as long as the forum does.

    You have the headers in backwards. They should go on the underside of the board. This will also allow you to put the panel on properly. 

    Try to get the main CS working before connecting any other modules (DOUT, AOUT etc.).

  21. Aout_ng last CV value - reset to 0V

    I think the CV staying at the last level is the expected behaviour. Also "off" would mean about -5V in a bipolar mode...

    If using a modular, then just pull out the patch cable :). Or solder a switch inline with the cable to shut it off when it's not required. Most modules I know will attenuate (full anticlockwise is 0) or attenuvert (middle is zero), so these are options too.

     

  25. Old music

    Thanks! The sound at the start is the Rhodes Chroma as are the later pads. I can't remember if it was going through any effects, but it's probably the raw synth. The bass is Moog Voyager.

    I have another one that sounds a bit like a didge, but it's just a Sherman Filterbank 2. :happy: It's pretty rough though, so I'll save your ears :).
