vst~ and MIDI control

    Jul 08 2006 | 9:46 am
    hi all,
    i know this topic has been discussed before, but i found an interesting fact that might solve the problem.
    i'm using a vst plugin called Mobius (a real time looper based on Gibson's EDP - zonemobius.com) and i'm trying to control it in real time with my FCB1010 MIDI footcontroller.
    when i'm sending ANY MIDI message (i.e PC, CC, note etc.) to the plugin i get the error: "Program (X) outside effect's range". :-(
    i tried to send a "midievent" (with the same MIDI number the controller sends) to the plugin and it worked just fine (!!), so i thought that the problem is with my MIDI interface/controller, but when i tried to use the plugin in other apps (Live, EnergyXT, Bidule) it worked fine.
    it seems that Max is not sending the MIDI message "as is" or it sends it too fast/slow....
    any ideas??

      the vst~ send midi controls (CC etc) in the range 0.-1., not 0-127
      you have to scale the incoming values
      __ as far i understand all hosts do the same, but probably the others
      do the math themselves

      hi kasper,
      thanx for the fast (!!) reply...
      can you tell me how do i scale the incoming values?

      scale, zmap, @, lp.smampf ....... and probably many other ways

      thanx again!
      but it still not working :-(
      i patched "midiin" to "scale 0 127 0. 1." and than to vst~ but i get the same error.... (with the new scaled values)
      also tried it with "zmap" but it didn't work...

      come on, read the help files and the reference manual !! it's all there......
      zmap works, you have to scale between zero and one (not minus one)
      and give the name of the chosen parameter as message (or it's number)
      kind of gain 1. or gain $1 or 1 $1

      yeah, i'll read the manual again.... :-)
      actually i mistyped the minus here in the message (but not in my patch...).
      hope i'll work it out.
      thanx a lot
