Noise-generating ICs<BR><BR></FONT></DIV><FONT face=arial,helvetica><FONT
lang=0 face=Arial size=2 FAMILY="SANSSERIF">Hi, I think this is my first post
but I've been lurking for months now.<BR>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?<BR>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.<BR>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...)<BR>
