LFOs

[Paul Maddox]

Dear All,

 Ok couple of questions regarding LFOs..

  Im developing a polysynth (with the interest of a certain synth
manufacturer) and I intend to make it
8 voice poly. Now couple of questions about LFOs,

  1) Should I have 8 seperate LFOs or one global? I dont want both.
  2) Midi Syncable LFO, Ive been advised that this is something they would
like to see,
        someone explain to me what it is, Im guessing that with each
successive midi clock received the LFO is
        stepped through its waveform. am I right? and if so how do you tell
it how many steps it takes to do a full
        cycle, ie 1 beat, one bar, 8bars??
   3) I would like the LFO to be voltage controlled (its going to be
programmable) and have a sine wave (if the
        above point is true then it doesnt matter as its going to have to be
a lookuptable anyway).

  oh, I also want it done with just 2 opamps (ie ONE TL072), I need this
thing to be compact if Ive got to build
8 voice cards. Trying to find an easy way to do 3 EGs under CV/DIGITAL
control. All with as few chips as
possible..

   Thanks for any help,

  Paul Maddox
