Open Music Labs has introduced x0x-heart – a new clone of the Roland TB-303 synthesizer voice.
Purists may argue that it’s a clone of the second cousin of a clone of the original TB-303, but $79 gets you a populated PCB + power supply. Buyers will need to add pots, controls & a case or panel.
x0x-heart is an SMT replica of the TB-303’s analog voice, complete with VCO, VCA, VCF, and envelope generators. It’s meant to be a base upon which you can build ‘a highly acidic synthesizer’.
Here’s a demo of the x0x-heart in action, sequenced by a 303:
We’d like to see complete kits for Euro and MU versions of the x0x-heart, too.
The x0x-heart is available at the Open Music Labs site.
Check out the x0x-heart and let us know what you think of it!
Like the page for a long time and building my one home studio, live at the top in a corner. Perfect for the studio.
How does this compare to a Volca bass in terms of sound & ability to tweak parameters?
That’s actually kind of cool when coupled to an Arduino step sequencer!!!
But does it sound EXACTLY like a TB-303???
Sound engine is very nice, only problem I see is sequencer that can generate nice slides and accents.
http://www.transistorsoundslabs.com Amazing 303 style sequencer with slide and accent. From the demo’s this sounds/looks very exciting – but no demo specifically with the xox heart.
very very very cool
i hope they make a mini sequencer too
unbeatable price
I might be starting to get a little sick of the vanilla 303 sound just as much as the myriad of ‘close but mot quite there’ clones. The 777 is the best acid machine made imho why can’t we get more stuff like that?
Will need to see how it can be controlled, but looks to be very nice. Shame the international shipping sounds so hit/miss/expensive. I got held to ransom by a very large US courier who wanted $70 in fees and taxes for an envelope containing a $30 download code 🙁
Roland have really missed a trick for decades by not re-releasing the 303, but instead churning out cr@ppy arranger keyboard after arranger keyboard.
i’m not interested in 303s that much..but i think this is a really really neat product for those that are.
Dudes the target there is the low price so stick with those basic tb features and if you want more features add it yourself , the diy way etc
Is it possible to use this as an external midi receiving device, ie a sequences from a midi send and manipulated like the old rack mounted 303 clone?
