You can immediately see the differences between the original OB‑Xa and the soft synth when you compare their oscillator sections.

Indeed, OB‑Xa V might more properly have been called OB‑X/Xa/8 V, although that would be a lousy name for a product. But while Arturia may have chosen the OB‑Xa name, they haven't stuck to the OB‑Xa architecture. Perhaps that was a marketing decision for reasons that escape me, the OB‑Xa has always had a better reputation than the OB‑8. (See the 'A Bit Of OB History' box.) However, I was a little surprised to find that Arturia chose the OB‑Xa as the basis for their OB‑series soft synth. There would have been little point in modelling the earliest of the OBs, the OB‑X, because it was closely related to the 4-Voice and 8-Voice, and that territory has already been covered in large part by Arturia's SEM V. But today, half of that has been corrected. I've reviewed many of these, but it always seemed to me that two of the greats were missing: the Memorymoog and something from the Oberheim OB‑series. In those early days, the company sometimes got it right and sometimes less so, but by the time that they released last year's V Collection 7, there was no longer any question that their software could successfully emulate a long list of cherished instruments. Arturia's latest instrument is a software recreation of Oberheim's pinstriped polysynth.Īrturia's V series of virtual instruments started in 2004 with Minimoog V, and this was followed by emulations of classics such as the ARP 2600, Roland Jupiter 8 and Yamaha CS80.
