Hi,

The list founder emailed me about this group - thanks! I joined via email
and would like to check out the archives but have not figured out how to do
so. Do I have to sign up with yahoo groups now? (Subscription did not
require this). Thanks.

polybox schemos?

2001-09-05 by Daniel Araya

Hi!

Anyone got a copy of the EML Polybox schematics they want to share?

Hey Daniel,

I have them, will try to get them scanned and posted to the files section
over the weekend.

Thanks!

I've been intrigued by that little box since i first saw a picture of
it ten years ago!
Maybe it's clone-time? :)

Daniel,
IMO the Polybox was overhyped although there's no question that it's a
very unique little beast.
Basically it is designed to track the pitch of one voice. Then it has 12
voices tuned chromatically apart from each other which can be played on
the 12 keys and will sound relative to the tracked pitch. The original
pitch always being the low "C" on the keyboard. For example, press the
"E" key of the Polybox keyboard and you would hear a voice that is a major
3rd above the tracked pitch. You can play "chords" or any combination of
the 12 keys or all of them. It does a couple of other tricks like it can go
up or down a full octave and has some phasing effects. It won't read more
than one voice and if you try, it will only respond with some chaotic
squawks. Same goes for noise and other sounds with no distinct single
pitch----of course chaotic squawks have their value too.
It does not translate envelope or filter from the original voice; the
orignal timbre is not preserved. The new voices are basically either on or
off as you play the keys and they are pretty much of a generic sawtooth
sound which you can fool with a bit on the Poly's controls. You could, of
course, run the Poly's output thru other effects and filters and such to
further modify it, but that's as much as it does on it's own.

Is it based around PLL (4046 or so)?

Sorry I don't know what that means. PLL=Phase lock looped? I seem to
recall that term being used in the description but not sure. Perhaps you
can tell more from the schemo's? I will try to post this weekend.

Hi!

I know that the polybox is pretty simple but i really like that kind
of machines! I have a few other weird little
boxes such as Perl Syncussion and Korg x-911
guitarsynthesizer so maybe i'll like the polybox!
I'm also on the lookout for a Paia Gnome...

I think so, and maybe some sort of octave divider too...

btw, nice to see a fellow s-diyer! :)

Do you happen to have schematics for them?

You can find the full article and schematics here
http://omega.tellus.vallentuna.se/anders/index.html
(with lotsa of other paia and diy stuff)
It's easty to build one (as I did, without ribbon).

If I remember corectly it has one octave or so, and having
input freq as lowest C, makes me think it's pll that feeds
some top octave generator like old 50240 (did I got it right)
to produce all the notes from an octave. Of course, both
parts could be more or less discrete, but that's what should
be in there IMO...

Phase locked loop
This thingies are common in such apps, basically they try to
"lock" on input frequency and osc at the same, but they have
overshoots during the process which make those "squaks"...

It'd be interesting for sure...

Sorry, no. I'll keep you informed if i find anything.
I can send you the schemos for the korg ms02 and 04 if you want.

Cool! Did you build an enclosure similar to the original or did you
build a completly new one? I really like the original
enclosure, maybe i can force Magnus Danielsson (sdiy) to sell me his
Gnome! :)

Thanks, I have them...

BTW, I have EML101 schems for VCOs,exp, and filter.
I'll scan them, I hope other members will contribute
to make full set of schematics.

Built it in toy keyboard, with small keys, dedicated lfo, and
new filter with FM (diode ladder), still with single lm3900...

Maybe, maybe ... :)
