Which MFOS should I get?
Hello,
I'd like to build a synth, and I'm sure a WSG would be fun. I am new to synths, but a little more experienced with building electronics. In the long run, building a modular is very attractive to me. What modifications should I make to the WSG to make it eurorack modular compatible?
Would it be better to just dive into making some modular components? Which ones are recommended to start with?
Thanks. Last edited by Netdewt on Tue Feb 05, 2013 10:27 am; edited 1 time in total

WSG is not remotely modular friendly. There is no voltage control, unless you add mods described on the page. That wouldn't be something I'd recommend as a first or early project.
I think you'd probably be much better served with one of the several Soundlab variations from MFOS. I still wouldn't want to panel it, but at least it could be hooked up to a modular, depending on how you patch it out etc. I've done one where I brought almost all the oscillators and things out to 1/4" jacks and it would be just as easy to do 1/8" jacks for Euro.
The WSG isn't designed to be part of a modular synth, but it is a fun project to start with, and could be easily added to a "real" synth as a strange noise or modulation source. _________________ What makes a space ours, is what we put there, and what we do there.

Ok then, I won't bother thinking about that for now.
Really, I'd like to build a Sound Lab MK II, or perhaps build multiple MFOS modular components, but I like to know what I'm getting into by doing the WSG first.
Other synths I am looking at:
Pittsburgh Cell[48] System 1
Doepfer Dark Energy
DSI Mopho (or used Tetra maybe)
Korg Monotron or Monotribe
Korg MS-20 (the new one)
Not really sure what kind of gear I would want ultimately (mono or poly, keyboard or pads, software or sequencer, or all, etc). I like music, audio gear, and building electronics. I hadn't realized this stuff was so fascinating.

You're doomed. I think the SL MK II would probably work pretty well if you are good with soldering and general electronics, Ray's warnings notwithstanding. The WSG is fun, I did one early on, but I rarely play with it much these days....

I know, and I have so many hobbies. I have been wanting to get back into music for 10 years, since I sold my stuff from high school band. I also just bought a ukulele to mess with, and we're looking into digital pianos for my kids to learn with.
Hmmm. Maybe I should take a closer look at the SLmkII... would I actually need an oscilloscope?
I had an instructor in college that is very into experimental electronic. He told me about MFOS in the first place I believe. Neat stuff on his SoundCloud:

No, definitely don't need a scope to get started.
Invest in a mid range digital multi-meter, probably around the US$40-60 mark.
The only reasons you wouldn't get a US$30 DMM?
1. One which will do frequency and duty cycle would be very handy.
2. A capacitance range will also show up on the US$50 DMM which has limited, but unique usefullnessl in these kinds of circuits. _________________ What makes a space ours, is what we put there, and what we do there.

I have a super cheapo DMM that I own, and I'm borrowing my brother's Fluke. It's more suited to home electrical though, I don't recall seeing capacitance or frequency on the dial.

I have talked to some people, located a scope I can use, and I am now thinking of building the Sound Lab mk II. It will be a challenge, but I think I can do it.
What d o you think about building a few modular components from MFOS, such as one of each, VCO, VCF, VCA, EG, LFO, wall wart power supply? That way I could continue to build more modules and buy additional modules in the future. My thought is that maybe they would be a little simpler to build and troubleshoot individually.

Like you said, i'd start building individual modules(i etch them myself so, etching a SL mkII won't be fun). Easier to troubleshoot, more fun, expandable, and more more modules

I do not know your skills, but you can also consider old good SL minisynth. That one was very good startpoin at least to me, and you can patch that out to be part of modular.

Why etch them yourself? That's what I keep thinking!

I am no expert, but I like a challenge. I've done a couple of electronics projects before. I have access to an oscilloscope and help from a friend.
Hmm, maybe. I was thinking that one earlier. I change my mind every day!

In my opinion, the biggest challenge of a Soundlab is the wiring Placing and soldering components is the same regardless of what you're making, but wiring and panelling a synth board without getting lost is definitely a challenge.

because its a lot cheaper than buying premanufactured PCB's (and a lot messier)
and once you get used to it, it's a piece of cake. _________________ _Richard_

Yeah, where i live, the usd dollar is expensive 6:1 . Shipping can take up to 2 months to reach my country. So, if i etch them myself i have them right at the moment when i want to. I don't like etching double sided, but the rest, it's fun, and i like drilling them

Unicorn Electronics (http://unicornelectronics.com/Transistors/FET.html) Has them for $0.12 each or $10 for 100. Not sure what Ray's pricing is about. I have a couple handfuls, but it's not necessarily worth shipping you 5 of them, even if I marked them up and charged you a dollar or two for them.
Of course, Unicorn has a minimum order of $25 (before tax & shipping), but that $25 will get you a fair bit more than 15 MPF-102's....
