SC Pro-One clone

[docbrown]

Have anyone in this forum have seen, heard, or read anything about a Sequencial Circuit Pro-One clone??

I'm looking for the actual CEM 3310 IC schematics..

thanks..

Damn dude you're like a dog with a bone when it comes to that synth ;)

OOps..

yea, file that under a big "DUH" for me doc.  I have a copy of that datasheet right here on my computer.  SO, the schematic doesn't look too ugly at first glance, I don't think it'll be that big a deal to get a discreet version that behaves similarly.

Now it's just a matter of getting the 3340's.  Synthtech has 'em for $40 a pop.  Would be nice to find a place that sells them cheaper in quantity..

If you do find it somewhere cheap, please let me know.. thanks

Is it any wonder?  Check out:

Check out the "Don't Go Replica" mp3 sample - yum!

Actually, That is the site that got me "Dis Dogg in me" -- super yummy.. Can I say woof-woof!! sorry.... ;D ;D

Yeh it sounds fat but so do lots of synths... I'd much rather a few of the oscillators and a few of the filters in modular format, than a real pro-one.... Why bother cloning something you can make even better than the original?

You got a point there.. In your opinion, which one would be a DIY fat synth that did not really need those CEM/SSM chips. Any links?

thanks..

Oberheim SEM

Minimoog

ARP Odyssey

Roland SH-2/5/7

Korg MS-20

;D

www.bluesynths.com has schematics for most of those

How about the CGS Modules?

[moogah]

CGS is good quality stuff for sure, and he has alot of unique modules.  Check out Blacet and MOTM as well.  MOTM is ending it's kit line in a few months, but he still has stock (and he'll sell just a PCB too)

[stryd_one]

What would be handy for us is an easy way to get the modules to use +/- 5V for CV.... They all seem to be 12 or 15V :(

the fatman from PAIA :http://www.paia.com/fatman.htm use a VCO based on a simple 555...

[DrBunsen]

You ought to check out paia.com's synth kits - the modular 9000 series and the Fatman, as well as their Theremin and other stuff.  From the front page, click on site map for a full listing of their products.

[docbrown]

Since I don't speak nor read German, I can only listen and look at those nice synths.

Questions:

1. Do you have to order the kit of SEMtex in order to build that synth?

2. Can you at least just order the schematics? or is it free somewhere?

thanks..

[moxi]

Don't say "semtex", it's a product to make bomb! the CIA will think we do detonateur with just a CORE and a Dout module (Maybe the next MIOS toy of the week!!  ;D)

for the CEM ship, all datasheet are available  @ http://www.synthtech.com/cem for free, for the paia synth, all schematics are free too :

the fatman : http://www.paia.com/fatmwork.pdf

for old synth, if you want to clone one :

http://www.synthfool.com/schm.html

here are the schematic of the prophet VS that use ,for example, the CEM3379 chip (24db lowpass filter + VCAs..

;D ;D LMAO ;D ;D ;D Don't forget an VFD module that will do the count down. ;) just like in the movies...

These are good stuff.. ;D I'm bookmarking like a mad man right now!!!

I swear, ever since I joined this forum, I've learn so much about the inner workings of the synths.

I figured, before I start building my own synth, I should study more about it first. ;)

You guys are awesome 8) 8) thanks..

Kinda late into this one but:

http://www.musicfromouterspace.com/analogsynth/SOUNDLABMINISYNTH/soundlab.html

Very nice DIY synth with moog style filters and 2 osc's. Makes a nice match for midbox-cv

Dude, its never to late!! I am still deciding on which one I will build!!

Thanks for the link!!

[stryd_one]

Yeh I like the soundlab... They're a nice spec, extremely well documented, lots of mods, lots of users, nice price, etc etc. In short they're real good ;)

I thought a lot about a Midibox SoundLab, but in the end I just thinking, "I'd rather spend it on another MBSID" ;)
