Best Ambient Synth Shootout #129: Soulsby Atmegatron - Song 1

video upload by Christian's Sonic Spaces

"This is the first song with the Atmegatron. It is a monophonic 8-bit synthesizer based on an Atmel 328P processor. The open source concept allows to install alternative firmware versions that increases the sound possibilities. This song used the alternative firmware Strings.

I used for the recording the following FX chain:
Atmegatron - Zoom MS-70CDR - Pigtronix Echolution 2 Deluxe - GFI System Specular Reverb 2. Depending on the recorded track some FX are deactivated

The signal went through a Presonus StudioLive 16.0.2 into the PC via USB for recording. To create the complete song I recorded consecutively several stereo tracks. The final song was then mastered with a bit EQ and compression on some tracks and some limiting on the master track."

Elektor J2B Synthesizer First Demo of Prototype from 2014.

"This video shows Elektor's J2B Synthesizer prototype running a soft synthesizer engine ported from the ATmegatron by Soulsby. Listen carefully to the sounds produced by this beast and admire the way you can control it. LPC1347 rulez the waves :-)"

via this auction

"This is a port of the Soulsby Atmegatron 8-bit monophonic synthesizer to the Elektor J2B LPC1343 ARM Cortex-M3 board. The original Atmegatron is based on an 8-bit, 32 KB flash memory ATmega328 and the firmware is available as an open source Arduino sketch. The J2B board has a 32-bit LPC1343 ARM Cortex-M3 processor with 32 KB flash memory.

The Atmegatron has two rotary encoders, eight potentiometers and a pushbutton. Two potentiometers are for volume and bass boost, the others control the synthesizer itself. The J2B board can have up to nine rotary encoders, or eight plus a pushbutton.

The Atmegatron uses a bunch of bi-color LEDs to interface with the user. The J2B can have an LCD.

The Atmegatron uses PWM to produce its sound, the J2B has excellent PWM capabilities.

Based on the previous observations, porting the Atmegatron to the J2B should not be a huge task, which is why I started doing it. The most daunting task was to replace the analog potentiometers by rotary encoders while keeping the same feel.
Two rotary encoders replicate the Atmegatron encoders, six others simulate the potentiometers. The bi-color LEDs are replaced by a 2x16 LCD, but I added two bi-color LEDs to indicate the red/green modes of the synthesizer.

A cool thing of the J2B is its built-in USB capabilities making it possible to update the firmware from any Windows PC simply by copying a file to the board which is seen as an external drive. No programmer needed at all.

PWM capabilities of the LPC1343 are a bit better than those of the ATmega328, which allowed me to increase the sample frequency and gain a bit, making it a 9-bit synthesizer. So, in theory, the sound quality of the J2B synth should be a little better than the Atmegatron."

"The Atmultitron from Soulsby has been in development in for a number of years now, however it is almost at the end of the development cycle and Paul was on hand to give us the run down. The Atmultitron is the big daddy of 8-bit synthesizers, 8 synth engines, analogue filters and VCAs with CV i/o and more."

8-Bit ARP Odyssey?? An exploration of the Soulsby Odytron

Oscillator Sink

"The Soulsby Atmegatron is a synth I have woefully neglected as of late, so in an attempt to reignite my enjoyment of this little 8-bit friend, I flashed it with an alternative firmware transforming it into the Odytron.

The Odytron is a true 8-bit emulation of the iconic ARP Odyssey... which sounds like an idea that bridges madness and genius! In this video we take a relaxed sonic stroll through the synth's features and go on to build a few patches to see if it captures the soul of its analogue inspiration within its 8-bit digital heart!

Here are the songs I mentioned in the intro:"

"8-bit digital synth that can be programmed with several different synth engines... In addition to the synth there are overlays for each synth engine, which are easily uploaded to the synth via the included programming cable... You can switch between the engines as you choose on your own using the provided cable and your computer. (My favorites are the Atmegadrums and Odytron.)"

"Soulsby Odytron limited edition Atmegatron 8-bit synth - Complete and Pristine!. Comes with power, programmer cable, overlays, quickstart guide and manual. Super clean and in perfect working order.

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 (see photos - this is unit 65 of 150).

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)."

Creating a synthesiser ecosystem with Soulsby Synths // Superbooth 2019

Published on May 28, 2019 DivKidVideo

"The whole family is coming together in the new ATX system from Soulsby Synths. There's the existing Eurorack Oscitron (demo video below) and Oscidrum (alt. firmware) but the new Atmegatron, Atmultitron and new expanders are all coming together for future release. Blending 8 bit "dirty lo fi" filters and polyphonic analogue filter expanders in Eurorack there's a potentially large system of Soulsby goods on the way!"
