Merry Christmas!

Here's a little Xmas present: Reason Combinator backdrops courtesy of Richard Hider (aka Tonal Axis). Here's the link.

It's been a great year, with trips to NAMM, Superbooth, Ginko Modular Fest, Barcelona, Synthfest UK and a whole host of 1-dayer events in the UK. Now that all of the Atmegatrons have been sold (actually there's 1 Pete Fowler edition left at the time of writing!), there will be a bit of lull whilst I'm working on a new very exciting synth that will be appeal to both modular and non-modular users. More info about that in the new year - join the mailing list for the latest info about it! Of course I will continue to support the Atmegatron, mini and Oscitron too.

Merry Xmas and a Happy New Year.

Latest DivKid videos

DivKid AKA Ben Wilson has been very active uploading videos recently.

Firstly at Leeds Modular Meet back in August, where I did a presentation on the different software versions for the Oscitron. If you have an Oscitron module and want to try out the Oscidrum and Odytron firmwares, grab an Accessories Pack on the webstore.

Secondly at SynthFestUK earlier this month. He caught us setting up our rig and testing it with a bit of early Human League. If you haven't heard their first album Reproduction, I highly recommend checking it out!

The highlight of SynthFestUK was when Martyn Ware (Human League/Heaven 17) stopped by for a chat, had a play with our synths and even purchased an Atmegatron!!

Thanks to Tony Adamo for the pics

NAMM 2017 Booth #5000

The Oscitron is launched!

Soulsby Synths have launched their first Eurorack module, The Oscitron, on the first day of this year's NAMM show. It is available from their website and will soon be available from retailers (see website for list). It comes bundled with the Uni-Five utility module for £260. The modules are also available separately.

The Oscitron is an 8-bit wavetable oscillator. The audio engine is based on the Atmegatron desktop synth module but has many differences too. These include an audio input that can sample wavetables and an adjustable audio engine resolution.

Other features include pitch quantizer, 15 filter algorithms, wave-crusher pulse width and phaser effects. There are 5 CV inputs, a clock input which can be routed to many parameters and an audio input and output.

As with the Atmegatron, there will be numerous software versions released for the Oscitron. A port of the the Odytron analogue modelling software will be released soon after launch.

The Uni-Five is the companion module to the Oscitron and converts bipolar LFOs and 8V envelopes to 0-5V control voltages suitable for the Oscitron inputs.

Pete Fowler limited edition Atmegatron

There are 2 other exciting announcements at NAMM this year. First a new limited edition Atmegatron designed by Pete Fowler (Super Furry Animals / Monsterism). Only 30 have been made, each signed and numbered. The design features a bright pink glossy finish with monsterism screen print patterning.

The Atmultitron

Finally, the initial prototype of the Atmultitron is on demonstration. It is a 6 voice polyphonic 8-bit synthesizer with 3 octave keyboard. The final specification will feature Eurorack connectivity and wavetable sampling from the Oscitron, along with sequencing and versatile modulation routing. The Atmultitron is aimed to be released in mid-2018.

“The initial prototype of the Oscitron was premiered at NAMM 2016”, said Paul Soulsby CEO of Soulsby Synthesizers. “One year on we are delighted to launch the finished product and premiere the next big project, the Atmultitron.”

Happy New Year from Soulsby Synths!

The Oscitron

And to kick off the year, here's our brand new product, the Oscitron! It's an 8-bit wavetable oscillator rammed full of features, some from the Atmegatron and some new. We're also launching it's companion module, the Uni-Five. It's a utility module that converts bipolar LFOs and 8V envelopes to unipolar 5V control voltages.

It launches on the 19th Jan. It's £260 (inc VAT) for the Oscitron/Uni-five bundle. The modules are also available separately.

There will be more demo vids and tracks coming up over the next couple of weeks. Click the link below for a 2 minute introduction.
