Watch the first video demonstrating the new Odytron Special Edition Atmegatron here!

The Odytron software is a unique combination of analogue synth specification with 8-bit digital implementation. It is bundled with a programmer cable and 3 overlays (Atmegatron, Delayertron and Atmegadrum), so there are 4 synth engines available out of the box.

The Odytron Special Edition is strictly limited to 150 units and will retail at £225 (inc VAT).

Email the waiting list to reserve one today!

Update: Here's a playlist that will contain all the vids.

The perfect stocking filler for only £29 / $39 / €39

The miniAtmegatron is back in stock at the Soulsby Synths Webshop.  Again this is a limited run and exclusive to the webshop.  This 90 second video goes over what the miniAtmegatron is and what it can do.
The miniAtmegatron is a synthesizer DIY kit for the Arduino Uno.  It can be bought with or without an Arduino Uno clone, preloaded with MIDI-hack and miniAtmegatron software.
Some previous soldering experience is recommended and the build time is between 30 minutes to an hour.  There is also a tutorial video.
Once the PCB is assembled and connected to the Uno, it becomes a powerful 8-bit synthesizer featuring: 16 waveforms, 15 patterns, 15 filters, 2 envelopes with 16 preset shapes, 1 lfo with 16 speeds and 16 shapes and portamento and wavecrusher effects.  You can't find value for money like this anywhere else! 

...and if you've already got one

there will be an enclosure for sale later this month, created by our friends at Bastl.  It is a plastic panel kit with all the screws necessary to hold it all together.  The prototype is shown below - the final product will look slightly different.
And don't forget it's big brother is still available at the Webshop.  The Complete Atmegatron is packed with extra features and most importantly it can be transformed into completely different synths, such as drum machines and delay effects machines.  This 90 second video covers everything.

If you're based in New York, I highly recommend visiting the Brooklyn Synth Expo this weekend.  There's Atmegatrons and miniAtmegatrons to try, as well as a whole host of other great synths.

I just thought I should provide a little update with the status of this.  The Librarian software is written in Java, which is generally great as a cross-platform environment.  However the Atmegatron uses SysEx to transfer messages to and from the Librarian and Java on OSX doesn't support SysEx (no idea why!).  Luckily this developer kindly provided a workaround for this and up until now the Librarian worked just fine under OSX.
However with the latest OSX/Java versions that workaround actually prevents the software from opening.  This is because it hangs when it tries to access the MIDI devices.  Full details of the bug can be found here.
So sadly for the moment my hands are tied.  Ultimately I think the solution is to port the Librarian to another cross-platform environment, possible something like JUCE and I'll post updates with the progress.
Please feel free to post questions about this issue on the forum and I'll do my best to help.

Sell out!

The miniAtmegatron has now sold out. I'm pleased to say that it will definitely be back though. It will take a couple of months to get a full production run setup, so please bare with me! I'll provide regular updates on this site.

Want to change channel?

If you were wondering how to change channel on your Atmegatron, here's a quick video showing how. I forgot to put it in the manual. Oops.

The pipeline

After an amazing synth convention at Incubate in Tilburg, I'm back to work! 

The Odytron will be the next software to be released and that should happen by the end of October.  There will also be an official overlay printed, available separately or with the Delayertron and Atmegadrum.

I will also be creating the miniAtmegatron official enclosure with help from Bastl. Will hopefully have some pics of the final prototype soon.

There will be a miniAtmegatron Workshop on Sat 19th Sept at 18:30, as part of the DIY synth convention at Incubate Festival.
Email me to reserve one, there's not many left!
Cost is €39....however a MIDI-hacked Arduino Uno will be thrown in FREE! This offer is only available at Incubate.

Also....There are also B-stock Atmegatrons available to buy at discount prices
