"VCO -> mult -> filter/phaser/ringmod -> filter/phaser/ringmod -> 3p mixer;
EG -> dual VCA A input -> 2nd dual VCA A input/filter freq cv;
2nd dual VCA A -> phaser freq cv; 2nd dual VCA B -> ringmod freq cv;
lfo sawtooth -> Dual filter -> VCO 1v input
modulated to taste.
the EG was just for sweeping everything. but for just straight up noise they can be omitted.
like Rlainhart said i'm just feeding sinewaves(oscillated dual filter outs) into the VCO 1v in
i'm gonna try a more extreme version once i have access to more sinewaves. thanks Richard."

"If you feed enough inharmonic sine waves into the frequency modulation input of a VCO, you'll get noise, or close too it. The last piece on this page:

'A River On Cold Mountain', uses that technique. No noise, no filters, just FM sine waves."

Sequential Circuits Prophet 5: Adding MIDI Compatibility
YouTube via gearwire
"Ever been searching for gear on eBay or craigslist for, let's say, a Prophet 5, and you come across a price that's just to good to be true, and then upon further inspection you realize that some dude is selling a non-functioning unit, which is why you can actually afford it, so you throw your hands up and curse the heavens for knowing nothing about soldering or even electrical engineering?
Chicago DJ / Producer Ross Kelly had this exact experience, except he actually knew how to make his basement-find fully-functional once more. Not only that, be he added MIDI compatibility in the process. Show-off. In this video he runs through the multitudinous and now-working sounds of his Prophet 5. See more on Gearwire.com."
Live Techno Jam 3
YouTube via siedgey
"Evening all! Here's a wee jam that Mr Copy and I had earlier today - we decided to dodge the minimal for a bit and make something harder...this is what came out.
It only took us 1.5 hours so keep your words kind - it was just for a laugh! As always, thanks for watching - check out Mr Copy's new release "Minerva" on Soma Records on June 16th - it's a belter!
I have produced versions of my latest videos (and one other that's not a video yet) on Myspace and they have been attracting some nice attention...I'll let you know if anything comes of it all. ;)

Modular jam
YouTube via shadowfac
"Sounds by synthesizers.com modular controlled by Mobius sequencer controlled by MIDI keyboard, and Moog theremin. Effects by Electrix Filter Factory, Yamaha E1010 delay, Lexicon MPX500, and Line6 Bass POD. Beats by Korg ES-1. Audio sync and keyboard playing sucks."

"I call this battery operated house... Had the 3 and 5 on batteries and for some reason the gear started to get off sync????"
x0xb0x #357 (Roland TB-303 clone)

"x0xb0x #357 -- the USA b0x
red, white, blue LEDs
mods include:
- gate on forever (switchable)
- vca on forever (switchable) - use in conjunction with gate-on forever mod for best effect
- on/off switch
- increased filter resonance
- env mod adjustable to 0
- increased accent "wow"
the internal, non-switchable mods have been generally accepted by x0xb0x community members as a very desirable combination of subtle modifications to increase the "drippiness" of the x0xb0x/303 sound."

Akai ME-20 A Midi Arpeggiator
via stamba on the forum
If anyone knows where to find a manual for this please comment or shoot me an email. You can find my contact info on the bottom right of the site.
BTW, I'm open to posting questions for people, just send me something worth posting with the question like an image, video, audio or other. Something that would warrant a post without the question. Just like band promo posts and the like. Hopefully I won't regret this. :)
Update via b rock in the comments (be sure to check out the comments for more):
"I happened across this thread while I was looking for background information myself.
Re: an ME20A manual. Here's a link ...
I haven't pursued that one yet, as I'm just looking to verify what I may have missed in my own explorations. (I've been putting together a .pdf for the newly-revitalized PatchArena.)
I've had an ME20A for years now. The key to using it is in embracing the quirkiness of the design. It's certainly an arpeggiator; just not in a modern sense of the term.
There are 3 algorithms: the usual Up & Down, plus a programmable Seq pattern. Rec Pattern determines octaves & direction. Rec Chord determines the notes that all three algorithms act upon. I don't have any numbers on maximum length yet.
MIDI In is for recording purposes only. The arpeggiated notes don't act upon live input. These are transmitted by Play, or a latching-type footswitch. The parameters cannot be changed with a footswitch plugged in, unless the 'latch' is currently pressed. Play or Stop is triggered on the footswitch release.
Step either extends a recorded note in progress (before note off), or can be entered as a rest by footswitch or front panel. Really old school here.
There is no MIDI Sync on the Speed, although I've used it as a master in a Tap Tempo routing. Gate Time literally lengthens or shortens the MIDI note output. Dynamics varies the velocity values of all outgoing notes from v=1 to v=127.
This may all sound confusing, but it's much easier in practice. That's one reason that I've undertaken an explanation in .pdf format. A picture is worth a thousand words.
In the meantime, I hope this helps someone get started. The ME20A is really a unique & useful device. If you get the opportunity, grab one before it catches on ... ;-) "
