Thomas Henry X-4046 VCO - Thoughts?

Post by lorenzovektor » Mon Nov 14, 2011 6:21 pm

I bought one from Negativespace (Manhattan Audio).

So far I think the saw sounds pretty good, I like the skew waveform output also.

The sync also sounds pretty good.

I'm prretty satisfied with mine. I see the price has gone down a good chunk from when I bought mine.

Any body else have one besides me?

Thoughts/suggestions/concerns?

sure. its a badass oscillator. :guinness:
its the reason i sold off all my euro oscillators. i can get just about everything i liked from the cwejman dual oscillator out of two of these.
in fact, these are now my only oscillators. i need to build more!

The FM on these sound great, and the raw waveforms work really well with wavefolders. I'm about to sell my anti-oscillator due to the X-4046 and TWF DIY builds. Highly recommended.
thank you thank you thank you

My X-4046s have become my workhorse oscillators - the only one I seem to use more is the Z3000. I think that if it were available commercially or if more people on the forums were familiar with it, it would have a bit of a cult following. (Or maybe if I did a good demo video, which I'm not equipped to do. The few samples available online are pretty weak compared to the real thing IMO.)

The sound of the its sync beats anything in my studio by far(now or ever,) and I really like the linear FM a lot. There are no geometric quirks to the saw or sine on the 'scope, and both sound superb. Depending on the 4046 IC used in construction the triangle can have a spike on it, but it's not problematic - it sounds very good and takes wavefolding like a champ. The skew can be interesting in the right patch, but I wish it was VC-able. I don't use it much.

As for the price dropping like that, part of it is that I was sort of guessing with my initial price. It's hard to set value on a module like that. I sold one other (and built 2 on commission) for the same price as yours, but this 3rd one just doesn't want to sell. I'm a little surprised it's gone this low and this long, but I think my first paragraph applies here. People just don't know what it is. I suppose I could keep it, but I already have two of my own. :hihi:

I built two a while ago and have to :hail: in front of Thomas Henry! That is a great oscillator, I can confirm everything Negativespace said, the sync is f...
incredible, I have no idea if there is any osc out there that sounds like that synced. Mine stays in tune very well (Much better than the M15) and is tunable (depending probably a little bit on the chip used) over around six octaves.
Skew is used quite a bit around here, saves me a mixermodule essentially. Having it VCable would be neat but needs a lot of extracircuitry, so I can understand that it is left out.
You can see, I am happy with that thing...

There you can read about it. Fonik sold a run of beautiful PCBs for the X-4046 VCO.

Wow, the PCBs are pretty cheap. Tempting but I've got no space left in my Eurorack and I'm not sure it will work with +/- 15 V.

in fact i calibrated this module with my 12V rig on the workbench, and use it now in one of my 15V cabinets without any changes :tu:

Also much love for the X4046 vco here:
stable tuning over 5-6 octaves, great sounds, love the skewing function, sync is brilliant.
My main osc in the system is the Macbeth X-Series Dual Osc which is just a fantastic module.... but the X4046 is far from being a disappointment, even when compared to the Macbeth VCO.
Oh yes, it works with +/- 12v flawlessly!
So - here's for Thomas Henry (and of course Fonik and his nice PCBs)

I've stuffed all of my boards, have all my panel stuffs mounted, and one board wired up waiting to be tuned tonight. I can't wait to finish this and take it for a spin!
Cheers!

his pcb project/availability page is here:
http://modular.fonik.de/Page29.html

...which lists the x4046 out of stock. pm him if you're interested still and maybe he will consider another run (as he's done in the past with other boards).

the simplicity of this VCO design is remarkable.

So, got a built dual version from Jan. I have had numerous OSCs and resold a lot of them. But this is definitely a keeper. FM sounds awesome (said by someone not fond of FM sounds), The dual architecture is totally awesome, they compliment each other perfectly. I've just played with them for 3 hours. The only negative point is that the Skew is not CVable.

I suppose you can CV the skew externally... run TRI and SAW into two ends of a VC crossfader. :goo:

Or cram a couple of XFader boards into the module...
