JoMoX Alpha Base Analog Drum Synthesizer

Hoax or not?

I see on their site that the XBASE 888/999 are discontinued.

Yes this is popping up in a few places, intrigued! No idea if it’s for real?

Jomox seems to plan a sampling & analog revival of the Xbase Drum machine series – which looks much like something that might bother Elektron (Rytm!) – they “took over” the parameter locks per step from Jomox. the Xbases had an interesting way of chaining / appending nearby patterns – just set the length to more one pattern could normally hold – and the next one will be used – brilliant.

Pic looks interesting, 16 steps but 11 pads? That suggests semitone tuning like the Rytm, just missing the octave? Sample engine like the Rytm too.

If you zoom into step 10 you can see a shadow under the letters which is weird. Pic definitely looks suspect!

Hey. I think if you zoom in you can see that the blurriness is from a clear plastic sheet. Looking forward to seeing more on this machine. Looks pretty legit to me. Just hope the encoders are better than on the case 999!

I had to sign up to this forum to give my two pennys worth but have been reading stuff on here for a while so hello everyone! :slight_smile:


Also the 999 has 11 pads. The 11th being the filter.

More exciting than Roland’s webstream


Haha yeah a little disappointed with that! It seems like putting a number on something is a selling point.

seems like a hoax… if you look close you can clearly see a plastic overlay

Yeah, can def see the plastic overlay in a few areas of that first pic, but maybe an early prototype case and the overlay just to help convey the concept/offer devs clear labelling whilst they’re tweaking final os etc?


If this is real I deffo want to try it… loved my jomox 888’ rough and heavy sound… the Software wasn’t the smoothest but I still miss it.

It’s real

Keeping an eye on that.

FM is beginning to creep into more and more product releases. :heat:


As much as I don’t trust Jomox, this interests me. I want so much to believe that Jomox has learned from all their previous mistakes/flaws with products they’ve released.

I didn’t realize there were demos. Wow, the sounds in those demos sound really good.

So you’re gonna test it for us? :grin:


lol not this one; I’d have to sell something

But man, it can actually sample, and store sounds to SD.


I got the gears going in your head

I’ve always loved the sound of Jomox’ synthesis.
Their sequencers, however, have not advanced much.

Can the Alpha Base sequencer do anything the Xbase sequencers cannot?
