I believe there is a "initial level" on the VCA that can override the VCA, just like a modular synth has.
So when you forcibly LFO the VCA level, it affects the initial level and you can hear the synth without pressing a key.
I'm betting you can adjust this initial level with a knob too, and just hear a forever droning waveform?

Thanks for posting. When I first watched that video, I thought the envelopes were broken. But after trying myself, I can repeat the same locked condition too. Had mine for several weeks and never noticed, but you can lock-up or latch the envelopes with a quick trigger. This only happens on the "slow" envelope setting, but even with all the envelope sliders in the down position, I can get the envelopes in a locked/latched state. Kind of like getting them in-between stages. I was able to repeat this with the keyboard, fast arp, and a fast external LFO into the gate input. Just set all envelope controls down, set ENV speed at slow, and a really quick staccato on the keyboard will latch the envelopes. So would be a design flaw/feature of this particular envelope generator. Not the keyboard, and no defect. Perhaps Arturia is aware of this and making a revision change? Seems like a diode might fix it as there is some backfeeding from the one EG to the other. FWIW, the old Moog 911 envelopes can go into a locked/latched state too, by sending to many consecutive rapid triggers. Never was a problem for me and easy to avoid. Interesting though!

The VCA thing is just the way they all work. An oscillator is always producing a constant tone. And via the envelope sent to the VCA, gives the effect of the oscillator starting, stopping, or fading away. Normally at zero volts nothing passes through the VCA. As soon as you apply voltage to the VCA it begins to pass signal. So by sending a voltage from an LFO, it passes signal acording to the waveform on the LFO. The filter has a similar effect in some modes. In lowpass mode, turned all the way down little or nothing passes through, even if the VCA is wide open. So the filter down will also restrict the signal ending up at VCA. And to further complicate things, the Minibrute, has more than one way of self oscillating with either filter resonance turned up, and/or the brutefactor cranked up, giving more than the one signal from the mixer/oscillator going to the VCA.

So the one I got is behaving normally, or like the rest of them. Good to know, thanks guys. I really did not want to have to send a second one back.

What was the problem with the first one ?

EDIT:
Ok, I've found your older posts.

The making of my modular... (ok it's in french, but the pictures are easy to understand !)

I got mine yesterday and it is pretty damn awesome. Unfortunately I might have to send it back to the eBay seller. I have the Release stick issue but more importantly the Ultrawave rate knob doesn't work.

These latest posts are very useful, now I will demand to try the unit out before I buy it, and check for all these little things. I'm glad I didn't order one online.

From the Arturia forum, a couple of notes about availability and reliability: http://www.arturia.com/evolution/smf/in ... pic=6897.0 Scroll down to the last post, from Bruno@arturia.

While I'm posting links, there are also long threads on this topic at:

Just found my receipt for my deposit - 26th January. This has to be one of the most delayed synth pre orders ever, right? For a synth that actually had working prototypes.

I can't remember how long my patch point SEM took but this is pretty bonkers.

Hmm... I've been waiting a year and a half for a $4000 Solaris. I'm enjoying my MiniBrute, though.

Did think of the Solaris when I wrote "working prototype".

There wasn't a Solaris prototype if I remember rightly? There were lots of different colourways on the CGi mock ups.

I heard people have been waiting for the solaris since 2005. So we've still got a way to go :)

I think the Solaris was first pitched in 2008 and I remember considering ordering one in 2009. There's been working prototypes for at least a couple of years. The first 3 dozen or so units have already shipped. Last year when when I found out there were some units available from the original 100 unit pre-sale, I placed my order. I was assigned a serial number in the 90s, but an email from JB a few months ago said I was bumped up to the 60s. Hopefully, my unit will be with the next 3 dozen units that should be ready late fall.

OK, back to the regularly scheduled MiniBrute thread.

so apparently the delivery of the second batch of Minibrutes has been pushed back yet again to the first week in November. could be a planned move to coincide with the holiday shopping season, OR...

Second batch..where was the first batch?

Kind of funny that not even actual retailers (music stores) can get a complete answer from Arturia themselves.
They just don't reply. And they have to contact the scandinavian importer, who don't really know anything either except they're delayed, but they "might come within 2 weeks". So they move their "unconfirmed date" a few weeks more ahead on the webpage. *sigh*

It sold out with preorders in February.
