usb midi connection


    Apr 09 2006 | 12:19 pm
    Hi all, I know this isn't a totally maxmsp specific question.......but,
    I use usb-midi on stage with my laptop (probably not the best idea anyway!!). If the cabe becomes unplugged, when plugging back in I have lost my midi connection with max or ableton etc, and have to restart to get it to work again. This of couse "on stage" is quite imbarissing.
    Does anyone else suffer from this problem? Or has anyone developped a working system around it? (like maybe even a non usb device for laptops!)
    many many thanks,
    jJ

      most of the time - on mac, with latest OS and latest mac, if you unplug/replug your USB midi, it still works. most of teh time, except sometimes, of course.........!!!! most probably the midi interface makes a differenec here - with an M-audio 2x2 it works
      but then i see no point in unplugging the usb on stage!! (isn't it better to gaffa-tape it???)

      Smartass remark: Don't unplug it on stage.
      I think it's software specific. I know when I'm using cubase and I'm pulling a USB cable out and I accidentally pull the entire USB hub out, the stupid Cubase makes me restart it.
      When I'm using max, I just have to plug it back in, then reset the connection or whatever, can be done with [midiinfo], load that object in max, and click help, and there is a nice little demonstration of what i'm talking about, it's a lot easier then restarting or having to reinit all the connections.
      That should do it, unless I'm way off on what you're talking about.
      Also, there's nothing wrong with USB, human ears can't detect the difference between firewire and USB, also it's just spitting out numbers, so unless you have like a 15 mile long cable, you're not gonna experience problems either. Unless you got like USB 1.0, but 2.0 is damn fast.

      You didn't tell which platform. On Mac and with a pretty unreliable emagic MT-4 its the other way around for me. Sometimes the interface doesn't work (I blame it to Emagic) after unplugging/replugging it works... (This technique doesn't work for audio interfaces, which I blame to Max, as it doesn't update the drivers though it recognises it with a message to the Max window...)
      I am sure on a PC this might screw up the Windows installation... (Another unfashionable reason for using Macs ;-)

      Thanks for you help, but no cigar, yes sorry I forgot to mention what my spec is:::: pc-xp, maxmsp, usb evolution keyboard (mk-249c).
      my test is simple,
      plug in the usb keyboard - load maxmsp - check it works (it always does) unplug the usb keyboard - plug in the usb keyboard - check it works (no!!, have to restart max, sometimes the have to restart the computer!!!)
      I tried to delete the midi object and create them again (in case it re-establishes its port address or whatever it might do, but no luck). Also tried your midiinfo idea - but it doesn't seem to do it for me.
      Thanks anyway!!
      I thought of getting a parallel port midi device with a screw connection (which I got a VP-11 off ebay, but can't find the drivers for xp.)
      so any other ideas would be great.
      many thanks

      If sometimes its necessary to restart the computer, it looks like an operating system/driver problem. Do other programms still work with the keyboard after the repluging procedure? If not, its unlikely a Max issue.

      no, i don't think it's a fault of Max now, it seems to be that case in Ableton and Cubase, although I've now tested it with a couple more usb midi devices including the midi sport 2x2 that kasper recommended and to no success.
      Have you tried to reconnect your midi device whilst max is running? Did it respond? if so what midi device / platform are you using?
      Cheers very much jJ
