problem with MIDI knob controllers


    Apr 14 2006 | 4:22 pm
    Cheers to the beautiful people of cycling.
    I am having a problem with knob midi controller. I want to set one controller?s range from 0 to 20000(Hz) but I can?t cause the max. number that my knob sends is 127. Is there a way to do it? And how? (with a comb of two controllers maybe? I don?t know?)
    (I know that is a stupid question?I have just started to use Max/MSP)
    anyway?thank all of you guys for the help!!!!
    Greetings??lstncrflly

      hi nihn.
      i used scale as you told me and it seems that i am loosing some freq. as i turn the knob.
      Is there a way to avoid these!
      thank you for your help!

      of course you'll lose some info - midi outputs 127 values. only. so
      you scle those to 127 values in between 0. - 20.000
      that's midi.
      what could you do??
      either a midi encoder ("infinite" knob) or maybe use 2 midi
      controllers - one for the rough region the onther one for the fine
      tunig - ok, you won't have 20.000 points (frequencies) but 16.129 -
      but it should be ok - if you want to see it differently, you could
      have a division down to 154th of a tone... not so bad
      if you want more precision, an encoder is the way to go

      ok i think I'll go for the infinite knob or a sensor midi controller!
      anyway, thank you for the advice
      good luck with your work too.
      best wishes

      If you want to control frequency the 7-bit resolution is too low
      (connectit to a [scale 0 127 20 20000] and listen to the result....)
      There is one official 14-bit controler in the Midi world called pitch
      bend, still a little low res for the whole range but much better. With
      xbendin you can track a pitchwheel.
      Elsewise its a question of your hardware, there are knobs which pull out
      higher precision controller values composed out of two different (32
      appart) controler numbers.
      If its a rotary controler you could try my dialin from the abhaXions
      collection at cyclings share pages.
      And don't forget to read the... but you know that. Beside the official
      ones I'd recommend all of the Max tutors from Peter Elsea , they cover
      also Midi problems ()

      do not expect from a sensor midi controller more than 127 steps
      it's midi, you know...
