guest — Mon, 09 May 2016 23:53:37 +0000

We are happy to announce that Crowd Supply is collaborating with Open Music Labs to bring a fully assembled x0x-heart into your Eurorack modular synth. Up till now, we only carried the kit variety. So for those of you itching for acid (and not soldering iron burns), swing on by the x0x-heart Crowd Supply campaign and check it out!

My summer vacation, by guest.

guest — Sat, 03 Oct 2015 13:54:55 +0000

Have you ever wondered how to get the lowest distortion out of an LM13700? Well i did, and now i regret it! i spent the entire summer ripping apart circuits, rebuilding them, scratching my head, building them again, and smacking the test equiptment until i finally understood what was going on under the hood. Seriously, it wasn’t healthy for me or my test equiptment. So, as a public service, i am posting the results here, so no one ever has to do this again.

Minimizing Distortion in Operational Transconductance Amplifiers

If you are interested in reducing the distortion in the LM13700, CA3080, BA662, BA6110, CA3280, or any other Operational Transconductance Amplifier (OTA), then this is the paper for you. Just click the link above, and you will be on your way to building cleaner VCAs in no time. And, as an added bonus, completely free to all of us, these methods also reduce the temperature drift of gain. Have fun, and as always, best of luck on your builds!

Codec Shields on Sale!

We have dropped the price of the Codec Shield down to 29$, so if it fits your bill, swing on by synthcube and pick one up!

Temperature Compensation of Analog Exponential Converters

guest — Wed, 11 Mar 2015 06:59:57 +0000

Say WHAT??!!? Everyone loves analog, right? Too bad analog oscillators tend to drift with temperature. But exactly how much, and why, and what can be done about it? We recently finished an in-depth analysis of the main culprit in these circuits: the exponential converter. This is the part that converts the input voltage to octaves at the output. If you’re interested in finding out more about these circuits, and how to keep them stable, the following paper could be for you!

Thermal Compensation of Analog Exponential Converters (PDF)

It has a bit of math in it, but it’s written to be accessable as possible. It’s also not completely finished, but what project ever is? Knowledge just keeps expanding, leaving the world feeling smaller and smaller each day.

OML now distributing through SynthCube!

guest — Sat, 13 Sep 2014 23:11:50 +0000

We are pleased as punch to announce that Open Music Labs is now distributing through SynthCube. This is advantageous to us, as it will free us up to focus more on design and less on the business side of things. And, its advantageous for you, because it means your products will get shipped out faster, and can be bundled with other useful synth products, saving on shipping costs. Note: this also means we no longer sell directly from this website, although all the pages and info are still available here. The store links will now direct you to SynthCube. So check out the SynthCube store, and let us know what you think.

Shipping hiatus and new store!

guest — Fri, 05 Sep 2014 06:08:31 +0000

We will temporarily stop taking orders on the openmusiclabs site later today (Friday). This is in preparation for our store move, which should be up sometime next week. We apologize for the inconvenience, but we think you will be pleased with the new store. Orders will definitely go out faster!

And as always, thanks for your understanding and support.

x0x-heart panels are in!

guest — Tue, 10 Jun 2014 23:25:47 +0000

Eurorack panels by Grayscale have been shipping, and they are getting more in stock, so be sure to check out their x0x-heart store to pick one up. They also have the pacemaker PCB in stock, which makes short work of adapting the x0x-heart to the eurorack format. It pins out all the useful controls, including gate, accent, CV, waveform select … the list goes on and on. And we still have x0x-hearts in our store, if you need a bit of modular acid in your life.

BA662 Clone in stock!

guest — Mon, 07 Apr 2014 08:24:57 +0000

It is said that the future is just pieces of the past stitched together, and so it is with the BA662. We reverse engineered the now-obsolete amplifier so you can stitch it into your projects, and give them a new future. Whether fixing an old synth or building a new filter with a distinct sound, the BA662 Clone can be your time machine. Why should Dr. Who have all the fun? Check out the product page, or swing by the store and get your very own.

x0x-hearts back in stock!

guest — Wed, 26 Mar 2014 18:23:17 +0000

The drought is over, and once again acid rain will fall from the sky! The x0x-heart is our DIY 303 replica that makes it easy to build your own synth. Swing by our store and check it out!

Also, adapter boards to convert your x0x-heart into a eurorack modular are on their way – should be here in 2 weeks. In the meantime, check out the panel design by Grayscale.

Shipping Delays

Our shipping manager is a bit overloaded with other work at the moment, so we will be reducing our shipping schedule from 2 days a week down to 1 day a week. All orders will be processed on saturdays until we can figure something else out. Our sincere apologies for any delays.
