I must disagree here. If synthesis is a passion of yours think long-term. You might wish that you had purchased the Voyager on the front end, rather than reaching the limitations of the Sub a few years from now and trying to sell it at a loss and seeking the Voyager at a later date. I agree it may be overwhelming at first, but it is nothing that you can’t get over if you are passionate enough to learn synthesis.
Can anyone speak to whether or not the Voyager’s controls are more precise?
When you inquire as to what the Voyager can do that the Sub-37 can’t, then think about all of the CV ins and outs that the Voyager has. As of right now, the Sub 37 has no CV outs. The Voyager is an excellent controller as well as a tremendously powerful instrument. The Voyager also has much more preset memory. Then you add pot mapping and programmable sources and destinations to that, multiple keyboard triggering modes, stereo outputs, and a wider keyboard range. It’s Moog’s flagship instrument.
If you want to fatten up the sound of the Voyager, or sequence it, there are ways that you can do that with software/hardware sequencers or external gear such as distortion pedals that you can insert into the fx loop.
So in this respect, with the only exception being the paraphonics, the Voyager can approximate the sound and grit of the Sub-37.
If I was in the market for a Sub 37 I would wait and see what Moog is going to do with it. Currently it is in its “Tribute Edition” and Moog historically releases subsequent editions of their synths (See, Little Phatty Stage II, the Sub Phatty was outshone by the Sub 37). They might release a Sub 64 or something like that after another year or so or a rack mount version of it. The next edition of the Sub-37 may have cv outs.
The Voyager hasn’t changed at all in several years and hasn’t really needed to. But there is a new OS in the works I believe.
FYI, I have never seen a Sub-37 in person.
Edit: If price is a factor, right now is a buyer’s market for used Voyagers. I also purchased my Voyager and Vx351 from Novamusik for $2999. I have seen better deals than that also for new.
