Trigger Outputs!

I have had the pleasure to beta-test the S-trig trigger output extension. Here is a quick'n'dirty video of the result!

    Haha, the entire Korg MS-family was in on it. Plus their sleek grandchild Polysix. Sounds excellent!

    Same here, i tested the v-trig one.
    First the clock in/out didn't seem to work with anushri, but a ic turned out to be faulty in the anushri. (The hex buffer for clock io) I have not replaced it yet, but will soon and then be able to finally confirm the xlr extension is fully functional for v-trig.

    @fcd72:
    Will you offer special backpanels for the extension ?
  • julianjulian
    @loderbast you can also use a normal osc/lfo to test the clock input.
  • fcd72fcd72
    @loderbast
    I will offer whatever you like ;-)
    Available via Sonic Potions together with the extension i think - if not drop me a line.
  • loderbastloderbast
    @drkorg: very nice video! btw
    @fcd72: I'll contact you soon about that. i am nearly convinced i don't want a diy case after all and am leaning towards standart case + holes for trigger io jacks

    i can confirm the reset/clock stuff with c-trig works aswell :)
    there is still some strangeness with the clock in of lxr but i am probably just to tired right now to figure out wats wrong.
    ill do further tests soon.
  • julianjulian
    @drkorg I really like the video! quite some gear you've got there! :)
  • jannizjanniz
    Nice! I can't help it but each time I see/hear a Mono/Poly I fall in love love love with it.

    Cool!

    Would be sweet to be able to trigger the arp of my Juno60 and the sequencer of my JX3P from the LXR.

    How about an extension for four extra audio outs?

    Rvk
  • julianjulian
    Extra audio outs are nearly impossible since the cortex has only i2s ports to connect a Codec :(
  • AltitudeAltitude
    So is there any documentation of this mod? Is this something prepacked or can I do it myself?
  • julianjulian
    The documentation has yet to be written.

    There will be PCBs soon, but it is very simple. Just a bunch of transistors to bring the 3.3v signals from the Mainboard up to 5v and buffer them.
  • AltitudeAltitude
    sorry should have been more clear, by documentation, I meant schematic..


  • julianjulian
    I'll try to upload it tonight since I'm not at home at the moment.
  • AltitudeAltitude
    Dank!
  • julianjulian
    the schematics can be found here:

    I will post the connectiond iagram to the mainboard this afternoon.
    Gotta catch an appointment in the city now. ;)

    Is this what will be already included in Batch 2 boards?

    Just trying to figure out what I would need to "upgrade" on my Batch 1 LXR!

    Any idea on price and availability dates?
  • AltitudeAltitude
    You need to solder wires to the STM board to board header.  I'm just going to lay it out on protoboard, there is only 4 parts per channel so not really a big deal to make.
  • VarthdaderVarthdader
    It would be great if there was a "mod" section with clearly laid out instructions and BOM to do such an upgrade!
  • julianjulian
    I will add this to the documentation one it's written ;-) at the moment I'm still knee deep in batch 2 preparations.

    Thought it was this thread but it must have been somewhere else where you mentioned jacks being a problem with the 3mm plexi, these are the ones I use (for that reason alone) and they clear 3mm plexi:

    These are Kobiconn 161-7400-EX (mouser)

    my plan for the trigger extension looks more like this

    So I need PCB mounted jacks.
  • AltitudeAltitude
    slick,  Where will that sit? not a ton of real estate on the back
  • julianjulian
    it can be mounted just below the mainboard. Thats why I have to redesign the board a little bit before the final release - currently some of the jumpers and transistors interfere with the position of some components of the mainboard :p

    I also have to make the board a little bit wider to include another standof for stability on the right.
  • ClemduClemdu
    I have to say, it looks quite sexy :)
  • shiftrshiftr
    Does it need a bigger case for this?
  • fcd72fcd72
    Nope, this will fit into the standard case, just swap you back panel. I think it will be included with the PCB.....
  • shiftrshiftr
    Does this go straight on the expansion header? Looks more like it needs a flatcable..
  • AltitudeAltitude
    @shiftr no, there will be a new header
