OB-Xa - Oberheim vs. Arturia


Recommended Posts



TBH, I can only hear a wisp of difference between them. That's excellent news for people who don't have $5K for the hardware. Sweetwater is offering the Arturia version for $74. If you have a serious Oberheim jones going, I feel sure you can get over "settling" for a software take on it. Your ears are forgiving. A few days' playing and they'll latch onto the best aspects.

I'll be the crabby boomer...  he had these guys on a similar Wurli shootout, to which I wasn't impressed.  Got the feeling neither of them has every spent any real time with actual Ob's,  Wurlis or older gear.  Jack on the other hand always gets my full respect. 

 

Regardless,  liked the Arturia (which I own) better too.  The patches were indeed bit brighter- which I guess could fool you the same way if something is louder.  They also had a tad more release on the envelopes in some patches..   Blindfolded I'd  be fooled too except for bass patches.

 

For virtual , I think the Gforce OBX is worth a serious  look. For what it's worth, also has Tom Oberheim and Marcus Ryle's blessing.   Gforce just did the OB -EZ which is absolutely superb.   Before you plunk down on the Arturia, try the OBEZ demo.  Or just buy it.   Though based on the 8 voice SEM's,  it's got the OB mojo.   Simple interface, but enough to do plenty.   The price is a no-brainer. 

                       

 Been considering downsizing the studio, and Gforce's synths have made me feel I could live without hardware.  

This coming from owner of Obxa,  OB1k, and a Matrix 6.

SonicProject's OP-X and Synapse Audio's Obsession are two other excellent contenders for the Oberheim sound.

Some of the differences here can be heard in headphones, namely the pan spread and Voice Tuning. Voice tuning differences are one of the most important ‘re-discoveries’ in recent years as to why analog synths sounded so good. It’s also why the original Tom Sawyer res sweep sounded so good.

 

Voice tuning is a separate thing from the normal detune you see on the front panel - VCO1 & VCO2. This is about under-the-hood differences between the actual oscillators under each key.  Old analog synths had a different voice card for each note you held down (e.g. up to 8 voices), with inherently different tuning from card to card. The crucial thing is that each time you play a chord a DIFFERENT set of detuning occurs. 

 

Not all synths or soft synths have it. Its called variously VoiceOffset, Vintage mode, Pitch Drift (sic) etc. Some synths like Kurzweil’s allow you to build it manually, so you can also plug it in to the filter and envelopes as well.

 

It really shows up on the Tom Sawyer Res sound, where the original is clearly several voice cards with different tuning, filter and envelope sweep offsets - thats why it was so good.

This is a big selling point on the latest versions of Arturia's virtual analog machines, and it sounds really good... the problem is setting the values too high, which can cause your synth to sound just plain wonky. Interestingly, this idea goes all the way back to the Wave 2.V software, which had an AKKU (battery) button to simulate wobbly voltages that produced some of the PPG's quirks.

The Arturia sounds nice but it's pretty obvious which is which. That said, it could be a simple matter of patch programming. For example, the French Horn patch on the Arturia sounded radically different than the OB-X8 and the OB-X8 does indeed sound the same as the original OB-Xa patch.

I just tested that patch on the free OB-XD, and it destroyed Arturia's version in warmth. What a nice little piece of gem!
