  1. -----snip-----

    i do understand that a PCB desing change is only intersting i more people are interested in an other design...thats why i brought the idea about 4x4 matrix and LCDs here on topic to discuss it. :-)

    So if you think it is not interessting for more persons than me you can erase the wishlist entry of me in the wiki-page.

    4x4 is interesting as a concept, but probably less useful than 1x8, as for the LCDs : Why not just use a 2x16 LCD placed in the middle of every four encoders? It will probably overlap some of the LEDs a bit, but there would be plenty of space+they are a lot cheaper to use :smile:

     

    EDIT: To the guy that lost his boards - I don't think anyone stole them, I'm guessing that your package was nudged around a bit in transit, which cause the edge of the boards to start cutting a hole in the envelope.. This happened to mine as well, but the hole wasn't much bigger than 2-3cm, so nothing fell out (thankfully) :/

  2. So it's possible to press the button, twiddle a knob on your synth, and have it automap to _one_ encoder? (I think I'm in love if this is true)

    So you'd need n buttons, where n is the number of encoders you want to program this way ?

    Wouldn't it be easier to make the button go into "automap to next "twiddled" knob mode"?

    Or am I completely mistaken ? =/

  3. No problem, I can provide signed and unsigned format + the desired min/max range.Interesting, from where did you get this information?

    AWESOME! <3

    Now, I got this information while researching the Miniaks apparently really zany Midi/NRPN spec, so it's not guaranteed information (Hence the quotes around the entire block) :/

    There generally seems to be a cr*pload of "undocumented/meh, let's just do it our way" going on with a lot of things that are Midi related.. Blarhg.. :(

  4. Awesome ! :)

    Will it be possible to send "negative" values via nrpn ? (Essentially just Alesis/Akai f*cking with anyone trying to make a editor for their products)

    +changing the type of data sent?

    Apparently Alesis/Akai have managed to deviate quite a bit from the standard, not limited to :

    "MIDI insists MSB is sent for 7 bit NRPNs

    Alesis seemed to assume LSB is sent. As a programmer, this makes sense ... BUT it isnt the midi standard.

    MIDI insists NRPNs are unsigned 14bit

    Alas, again Alesis insisted on using a "signed" 14bit

    therefore value ranges like [-100, 100] are really [16284, 16383] [0, 100]

    most hardware interpets this as [0,100] ... [16284, 16383]

    Which results in either a large gap in the middle (not very practical)

    or, since most will not over/underflow to only choice is to use 2 controls,

    one for the -ve range, one for the +ve range."

  5. Someone stateside would have to ship a giant box to one person, or we would all be hit by import fees, I don't know anything about the Swedish system, but in Denmark we're hit for 150DKK if our total order (incl shipping) is more than 80DKK & from outside of Europe (150DKK ~26USD ? )

    Which is why I'm in favor of a "local"/european bulk order for encoders, but I know I don't have enough credit on this forum to be the one to start it (or enough credit in real life -.-), +shipping from Denmark is just as bad as shipping from Sweden :(

  6. that's how i understood it. it would be the easiest way to get both in a 1U unit.

    the only drawback is just that half of the jacks (incl usb) are turned around, and the numeric order is reversed too, as well as in and outputs.

    but no need to drill holes for panel mount parts etc.

    that drawback is actually not that bad if you're not gonna plug things on the backside every day.

    Yeah, you could just use panel mount midi connectors though (if you are going to have a front plate done anyway) :)

    Since my plan is to try to squeegee two 5x5x5's into one 1U rack, I'm probably going to buy one or two cheap 19' rack front blinds & some form of empty 1U rack case/drawer/something, drill some holes in the back (not going to be looking at it anyway) & wire 9 of the pairs to the back with panel mounts, and one pair to the front(+usb+status led).. Might even get a decent front panel made at some point.

    +1 for the latency stress tests using USB hubs.. Would be interesting to add a USB 3.0 super speed hub to the mix, to see if it performs any better.. Sadly those things are far too expensive at the moment :(

  7. So that half of the connectors are sitting upside down? Bad idea from a usability point of view.

    No, he said panelmount connectors, so the connections on the inside would be different, but you would just align the second set of connectors to the first one (they would be wired up anyway) ?

    Even if you use pcb/boardmount connectors, would it be so bad to have ~4x in/out on the back that are upside down?

  8. -Snip-

    i just looked we won't get 2 boards next to each other in 19" and on top of each other won't work either.

    so it would have to be all panel mounted. preferably easy to access midi jacks (Reichelt maybe)

    are there panel mount usb jacks?

    another way would be one on the front and one on the back, but wouldn't look so clean.

    about judging, there could be a poll and every member could vote if they like.

    How about one "the usual/right way(pcb bottom is touching the bottom of the case)" and one flipped 180 degrees (bottom of pcb is on top of the case) ?

    Panelmount usb exists, but look shite :

    .... Some sort of creative compromise would probably have to be reached, or a seperate thomann order for one of these : http://www.thomann.de/dk/neutrik_nausbb.htm or http://www.thomann.de/dk/neutrik_nausb.htm ?

  9. great idea technobreath (but i'm no admin)...

    maybe you could offer it as price for the best Schaeffer/FPE 19" 1U panel layout for 2 instances of the GM5x5x5, all in/outs on the back, on the front the usb,leds and maybe 1 or 2 pairs of midi jacks on the froont too for easy access on the fly, switchable!

    haha that's not at all selfish :rolleyes:

    the contest thing would be a great thing for beginners i think.

    Would make more sense if one or two pairs of midi connections were on the front, and usb on the back, this would allow you to run your usb cable out of the way (at the back), and still be flexible enough to allow you to test your newest midibox creation/diy/whatever thing that uses midi without having to crawl around the back of your studio for a midi connection :)
