A no-brainer if you don't already have it.

**correction - the price is for current Ultra Analog VA-1 owners.

weird.  it says $199 when you click the link

I think it is meant to be $149 now. Don't think it is $25 though.
 
If you really want a fat analog synth sound this is also a great synth and it costs less. It is seriously fat and analog sounding and Oberheim sounding as well. And it is only $59. It sounds killer and every bit as good as the AAS. I am just loving this right now:

It's $29 upgrade offer for current owners of Ultra Analog VA-1.  I like the first one so I'll probably pick it up at the price.  Gotta check out the demo tomorrow to be sure.

Sorry about that.
It's $29 for current Ultra Analog VA-1 owners.

thanks for clearing that up.  Jeff, that Oberheim clone looks tempting

Hey dubdisciple it is really nice. I have owned a few Oberheims in my day. I just know how they sound. This VST is right on the money. It is fat, floor shaking and simply wonderful. It takes me back everytime I play it. It has got a wonderful arpegiator too. Put all 12 oscillators into unison, hold down a low note, close the filter right down and then open it up slowly. You will faint when you hear this.
 
The AAS I am sure is cool but it is not modelled on anything. They have designed it from scratch to sound like an analog synth and I am sure it does too. But what is cool about the OPX is that it is modelled on a serious instrument and the Oberheim that had the original SEM filters on board too. You can also pan the oscillators for some really truly great stereo imaging.
 
I only have the OPX but for extra you can step up into the higher version which is even better. I am pretty happy even with the OPX. OPX Pro II looks cool.

Is the price difference (29/=) for different location / what you've owned ?

I've noticed in the past that prices can vary depending how you get linked to them.
 
If you use the link I posted at the top of the thread and go to the bottom page the prices you will see are:
$149 new license
$29 for Ultra Analog VA-1 users
$49 for Session users
These are listed as "limited time only", I think the email I got said till Nov 3rd.
 
edit:
Looks like the prices for new & upgrade from session have changed.
Also if you have another AAS product they have a different price for you.
Check your email for the offer.
 
While I like the sound of AAS stuff I was never crazy about their interface.
I think the new gui and preset browser are a major improvements. 
 

The link in the email ends up at $29 cart price (for current owners).
 
The original goes for buttons if you don't have it, so keep an eye out for that and upgrade.
