Hello...I'm new here. I tinker with electronic music devices, and I am trying to build a one-octave organ with 13
function generator ICs: 8038.
(I know there are better ways to build an organ,
but I want to do it this way because I have a bunch of these ICs).
I have one of these ICs working just fine, with a trimpot for adjusting pitch, on a breadboard. See attached schematic, accompanied by a pin explanation for the IC.
My question: How do I connect more than one of
these ICs to a single power supply (+-9v), so that I
get multiple tunable outputs?
I have two of them wired up on a breadboard, with
a trimpot on each to control the pitch. The two ICs share a +- 9V supply. I can
vary the pitch with each trimpot, but there is
only one voice heard.
I've looked for a schematic containing more than
one 8038, but can't find any.
I'm hoping there's an easy answer. I'm attaching my schematic for a single instance; it works.
Thanks!
