2 overlays made from high quality reverse laser printed vinyl:
- Odytron (analogue modelling dual oscillator with filter, sync, PWM and 2 modulation inputs)
- Oscidrum (8 part drum machine and 16 step sequencer with numerous tweakable parameters)
Quick reference / instruction card:
- Contains quick ref for Odytron functions and an overview of inputs and outputs of Odytron and Oscidrum.
- Allows alternative software versions to be uploaded to the Oscitron. These can be downloaded from the Soulsby Synths website.

One of the key differences is the ability to capture wavetables via an audio input. There is also a "continuous capture" mode which produces vocoder-style effects.
The resolution of the audio engine can be altered from the Atmegatron's 32 sample wavetables, down to 16 and up to 128 samples, creating radically different timbres.
There is a clock input that can be routed to many different parameters. There are 5 CV inputs for controlling the most common parameters. 16 patches can be stored internally. As with the Atmegatron, different software can be uploaded to the Oscitron. A port of the Odytron software is ready for release in the first quarter of 2017.
Uni-Five companion module:
The Oscitron comes bundled with the Uni-Five companion module. This is a utility module that takes 2 bipolar +5/-5V signals and 1 unipolar 8V signal and converts them to unipolar 5V signals, suitable for the Oscitron's inputs. This is most useful for bipolar LFOs and envelopes. There is also an attenuator on each input. The modules are also available separately.
