  Subject: [sdiy] Noise-generating ICs


  Hi, I think this is my first post but I've been lurking for months now.
  I'm looking to build an electronic drumset using a noise source split into
several identical channels, filtered, and mixed back together.  The trouble
is, the book I'm getting the basics out of (Build your Own Low-Cost Signal
Generator, by Delton T. Horn) lists two ICs for noise generation, the
MM5837N and the S2688, but a Googling shows that neither are easily
available.  Can anyone here point me towards another suitable IC?
  As background, I'm building a simple drum machine as a first sdiy project
(not very synth, i guess, but a good start).  I haven't purchased many
components yet because I want to make sure they're all available - so far,
that's the only one that's not.
  Also, are there any reasonable alternatives to optoisolators for
voltage-controlled resistors?  How is voltage control usually handled in
synths? (this one's been bugging me for a looong time...)
