If I understand your question, you’re asking about the differences between Voyager models. While no comparison chart exists, the differences between Voyagers are cosmetic only. Functionally, they are the same.
As you indicated, different presets shipped with each model, but all factory presets are available online.
Currently, Moog produces two keyboard versions of the Voyager: the Electric Blue and Performer. They also make a rack-mount version, known as the RME (Rack Mount Edition). Older versions of the Voyager include the Signature Edition and Anniversary Edition. These were special models that featured custom wood cases and badging. If you’re interested in these out-of-production models, you’ll have to look on Ebay, or contact a private seller.
The RME and EB presets have not been posted by Moog Music. That’s why I didn’t post them on SquareWave. However, this appears to be overtaken by events. All six factory banks (SE, AE, ZVP, TW, RME & EB) are included in the latest Editor update.
yes , I was asking about differences between Voyager models. Because I somewhere read about new software inside Rack Mount Edition and more polyphony … is it truth ?
Is possible upgrade all models with new software ?
The Mac version was done a few weeks after the PC version was released. ST added the extra banks in the Mac version and (I assume) updated the PC version as well. The latest PC version is 1.3, but I don’t know if it’s been posted on the Moog site. If not, I’m sure it will be soon.
The RME operating system (software) is basically the same as the Voyager’s, with just a few minor differences because of the different hardware.
All Voyagers and RME are monophonic only. You may be confusing polyphony with the new expanded memory feature. The original Voyager hardware could only store 1 bank (128 patches). The expanded memory gives the ability to store 7 banks (896 patches). New Voyagers and RMEs have the expanded memory. Older models can be retrofitted with a kit from Moog.
It’s true that a new operating system can ‘upgrade’ the hardware by adding new features. The Voyager/RME OS has been updated several times already, adding new MIDI capabilities, pot mapping and other ‘goodies’. The updated software can’t add features that the hardware doesn’t support, however (an update won’t make the Voyager polyphonic, for example).
