New warm sounds from the 8-bit Atmegatron

The much anticipated Odytron Special Edition is released today. The Odytron is a limited edition Atmegatron, pre-loaded with the brand new Odytron software and factory presets, as well as having unique Odytron paintwork. Only 150 units have been manufactured.

The Odytron is £225 inc VAT (approx $339) and currently only available from the webstore.

The Odytron software simulates the specification of a classic analogue synth but in an 8-bit environment. The result is a fascinating combination of analogue warmth and 8-bit grit. Features include: 2 independent oscillators (duophonic), 2 filter algorithms + bypass, 2 envelopes, LFO, ring mod, wave sync and numerous modulation methods.

Despite the sound being radically different to the original Atmegatron software, the Odytron is 100% Atmegatron compatible and comes bundled with 3 overlays and a programmer cable. This means that it is essentially 4 synths for the price of one. The overlays for the alternative synth engines are: Atmegatron (the classic software), Atmegadrum (drum machine) & Delayertron (delay effects synth).

Odytron software now on downloads page

Existing Atmegatron owners can download the Odytron software from the downloads page for free and can also purchase optional extras: vinyl overlay, programmer cable and instructions.

Back from LA, after a very exciting first NAMM. Will do a proper post about it in a day or 2. The new stock of overlays have arrived. Normal service at the webstore can resume and I'll start dispatching orders tomorrow. Many thanks for your patience!

Odytrons will be start to be dispatched from 1st Feb. Software will also go online then too.

Hall C, Booth 5000, 21st-24th Jan, Anaheim, CA

We are very excited to be exhibiting at NAMM this year and will be demonstrating a whole range of new products. We are part of the WMD Superbooth and are exhibiting alongside some of the worlds best indie synth manufacturers. If you are attending this year, we would love to see you! Here's some of the new products we'll have on display:

The Oscitron - Eurorack module

Soulsby Synths’ first Eurorack module is a wavetable oscillator. It features the biquad filter algorithms and wavetables that gives the Atmegatron its classic sound. In addition it provides an audio input to capture user wavetables. There are many parameters for capturing and processing the wavetables. The Oscitron will be launched later this year and there will be preview videos demonstrating its full range of features.

The Odytron Special Edition Atmegatron

The Odytron is a limited edition Atmegatron, preloaded with Odytron software and presets. The audio engine provides the features of a classic analogue synth, but in an 8-bit environment. It comes with a programmer cable and 3 overlays to use with alternative software. Available from the 1st February.

miniAtmegatron case

The miniAtmegatron DIY kit was launched last year and received an enthusiastic response. The offical miniAtmegatron case is simple to assemble and provides excellent protection for the PCB and Arduino. They are available from the Soulsby Synths webstore (click drop-down to select case).

See you there!

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.
