Surely the internal structure and parts are the same across the 25 and 37 that would mean they should sound the same?

from what i understand the sub 25 has even more headroom than the sub 37. if thats the case it could explain the cleaner output.

I asked Moog about this. Their response was that the subsequent25 and subsequent37 have the same audio signal path with identical headroom/distortion.

Both units are an improvement over the original Sub Phatty and Sub 37.

Now I just have to decide if I want to replace my Sub Phatty with the Subsequent 37 key variant and a screen that will eventually die, or swap for a Subsequent25 which will be a tank forever.

Beware synth companies thinking two similar synths must sound the same, coming from a production standpoint, because that's what the specs say. I've seen this happen time and time again in the audio world. The Sequential guys on here also even famously thought the Prophet 08 and Rev2 must sound the same, until people posted up the demos. There are just too many tiny variables that can change a sound, often between apparently very similar units.

I personally like the Subsequent 37 and love the Subsequent 25. Like other of the most recent Moog synths like the Sirin and Matriarch, it sounds more bright, open and free-running to me - key parts of the original moog sound, I think.

I really wish Moog would do a desktop or rack mount of the Subsequent 25.

Anyone having a Subsequent 25, disappointed he didn't get the 37?

I used to have the 37 and sold it because I just wasn’t using most of its advanced features. I recently bought the 25 and love it. Amazing sound and the keys are a huge upgrade over the 37.

You had the Sub or Subsequent?

Sorry - yes I had the Subsequent 37.

So you say Subsequent 25 sounds better, cause I am interested.
The keys are supposed to be with aftertouch on the 37..

Thinking of picking up a sub 25 for bass. Is it worth it?

Yes. It’s a bass monster. Check my patches here for plenty of ss25 bass examples

From Moog:

WE SAY GOODBYE TO SUBSEQUENT 25
Production of Subsequent 25 comes to a close.

Sweetwater has 'em on sale for $699 but... none in stock heh. Got done blowed out ayup.

just got my sub 25 today... definitely a fun synth and sounds really good... so much moog goodness in such a small package.

it's quite versatile and the presets from the librarian are great... and there are a lot of them.

really glad i snagged one of these while they're still available... and on sale.

a few days in and man i'm diggin this synth... it can get so chewy and grindy, but also so sweet and silky... great for leads and bass.

it's a deep synth for sure and with the editor, librarian and "hidden" features... i mean this thing even has a note calibration feature.

super cool synth... very happy with it, and at 700 bones, an amazing deal.

Does the editor support Apple Silicon?

Moog’s download page isn’t working for me at the moment for some reason so I can’t check.

Edit: Finally loaded, yes it does

They are back in stock by the way!

I did a bunch of looking around this weekend and I think this thread got the synth pretty wrong. At the current price… if you have a computer nearby it seems like a no-brainer it sounds absolutely brutal in a great way in the demos.

I’m sure people know this by now but it is not a cut down Subsequent 37, I had no idea until I saw this thread pop up and then read more about it elsewhere and listened to demos. INHALT’s video above is so damned good, and the price is now where it should be while supplies last.

I waited on the Sirin, not making that mistake with this. The past week has been wild for me and Synth deals, crazy. I’m probably done for the year

Cheers. It’s a seriously good sounding synth and the initial price was the one that made the most sense. The editor also REALLY helps with all the hidden parameters of which there are many. And yea it runs on apple m series just fine.

Please explain. There is a lot of misinformation floating around, so an explanation ( if this was explained elsewhere ) deserves repeating.

Afaik Subsequent 25 is a cut down Subsequent 37.

Am I correct in thinking this is a Sub Phatty 2.0? An old promo video for the Sub Phatty Multidrive is what first got me interested in synths...
If I wanted to add a bit of authentic Moog flavor, would this be a good choice?

Thanks -

If you have a computer nearby I think it might not be a bad deal. If not, look at the button combos for the secondary controls – they are insane.

Subseqeunt 25 is based on the Sub Phatty not the Sub37. The mixer has twice the headroom and can do nice moog leads which INHALT demonstrated really well in their video above, and the multidrive is, from what I understand, stronger on the Subsequent 25 vs. others.

I’m confused why Moog allegedly responded to someone saying it was the same as the Subsequent 37, the product write-up is clear about it being a successor to the Sub Phatty which is sonically distinct, but of course within a family of similar sounds.

I think these nuances matter a lot for a small characterful synth, I spent a long time listening to a/b comparisons once I noticed this deal and without having played either the Subsequent 25 sounds better to my ears, but this will vary of course and there are a lot of downsides: you need a PC or external controller to get the most out of it, also a sequencer.

The keybed while the best of the whole line, I think it is Fatar, is limited and has no aftertouch which filter cutoff does respond to so using an external one can be beneficial etc.

I have one coming in the post and will share some impressions sometime soon and hopefully sound examples in the next few weeks. I think the current price is great for what it is, but the tradeoffs are important to understand.

yea, the usb to pc connection running the editor makes a big difference.

not only the extra tweakable features, but all the presets too.

this is my first moog and basically my first "real" synth, because it blows the doors off of my behringer synths, which i think sound great, but this guy just speaks on a whole different level.

needless to say... i would recommend this synth, especially at the current blowout price, to anyone looking for a small versatile and great sounding mono synth.
