I was going to solve that problem by using a DSP to generate the
sounds digitally, and then pipe them through a DAC. Doing a VCO in DSP
code is pretty straightforward, but damn near impossible to do with
sampled sounds (if the control voltage for the VCO is varying, which it is
in Sound Boards like Star Castle)
IMHO, if you don't have the background sound correct for Star
Castle, it's not worth doing the other sounds.
On the brighter side, sounds like the "Star Sound" and the "Laser
Sound" which are quite complicated to generate "authentically" lend
themselves quite well to sampling, so there's advantages to each approach,
and a hybrid approach is probably the way to go to emulate all the sounds
correctly.
I wasn't planning on doing any samples, but I can see where it
would make life easier, especially with those two aforementioned sounds...
Like I told Steve, I'd be willing to help out whoever's actually
doing this, but I only want to assist. My time these days is short, and
I've lost my motivation for doing a Cinematronics multigame (I own almost
all of the complete games now -- It's amazing how far you can go in
collecting in one year!)
