"Hopefully he'll have a Euro version as well since Frac is on its way out. [ducks]"

ouch!

Perhaps he meant "Since the Frac version is on its way out to happy Frac users everywhere"? That's how I read it, anyway.

wacky that!!! :confused: a digi one with 8 VCO's???

There seem to be more Euro modules than Frac coming out lately. Of course, even if no more Frac modules were released you would have plenty to keep you busy for a lifetime.

Re Cloud Generator, I'm not 100% sold yet. The original chip he chose couldn't do sawtooth, so that was left off the original spec. Then he figured out he could do it with another chip so now the saw out will be a second expansion module. If the CG itself did saw (Supersaw) then it would be cool. I don't know if I need Supersine and Supersquare. And I don't want Supersaw enough to buy the CG and CGX. If you search for reports from the Analogue Heaven Bay Area gathering from last year, there are some videos of the CG in action.

I'm more excited about the quad quantizer that's on the way. He says that once all of the kits are out of the way he'll ramp up R&D. He's fallen way short of "Module of the Month" lately...

BTW, there's a thread on AH today asking about power requirements and FM voltages for the two Frac versions, so perhaps they're not as far along as I thought. Seems that the Cloud Generator may require 120ma of power and he's asking it that's too much.

The nice thing about this "Audioengine" series of modules is that future modules will be "just software" with a few hardware changes. I'm looking forward to see what crazy digital modules he comes out with. There's a digital noise on the way, for example.

I'm not into the "supersaw" sound really, and a bank of sines that can do additive type stuff is far more interesting to me! :hyper:

They don't do additive, the spread is from a fixed center frequency. So you get x, x+1, x-1, x+2, x-2, x+3, x-3, etc. You can control how wide the spread is and change the phase relationship between them.

So the CG has Supersine and Supersquare, where the CG expansion adds Supersaw and Supertriangle.

I realize that, but honestly it's close enough for me.

Quick question about the Music From Outer Space VCO kit:
http://musicfromouterspace.com/analogsy ... REV01.html

I'm looking at building one just for kicks, and am kind of confused about the panel layout ( http://musicfromouterspace.com/analogsy ... verlay.gif )... It looks like it's got four 1v/oct CV inputs-- is each of those inputs set up to control a different wave (e.g., one for the sin, one for the tri, etc.)? I can't really tell based on the example panel.
Any help/thoughts would be good... If not, I'll just get in touch with MFOS directly.
Cheers![/url]

no. they're not for each individual wave. just 3 v/oct and 1 lin.

Okay-- thanks for the info!
Now... (n00b question alert) why would you need three separate 1v/oct inputs?

One for note data.
One for pitched vibrato.
One for Exponential FM.
Voila!

Or, one could use more than one for pitch data. Keyboard + sequencer = transposed sequences.

One thing I'd recommend for extra control is to have attenuators on several of the CV inputs -- that's always been my approach, at least -- though many companies seem to presume you'll attenuate CVs elsewhere.

[My thoughts, generally -- present all things at full voltage and then attenuate at inputs.]

Hey, also, for VCO inputs -- try adding a 220n cap + switch on the input for switchable AC/DC coupling (this is meant to be especially useful for Linear CV input).
ie -- input socket to 220n cap to top of pot. middle of pot to CV input, low of pot to ground. Then add a switch 'on-top-of' the cap so when it is closed it bypasses / shorts-out the cap (that'd give DC coupling compared with AC when open)
