ROAT is an 8-bit experimental oscillator inspired by the Soma "Rumble of Ancient Times" synthesizer.
It includes 4 oscillators that can be triggered independently, by pressing 4 different zones of the keyboard, or recording a step sequence.
Combining oscillator activation with the different settings per oscillator (pitch, shape, LFO) and different combination algorithms, and adding randomization and chaos, gives you a wide range of sonic possibilities, from melodic to digital noise.
Settings per oscillator:
- Pitch
- 16 different waveshapes
- LFO (for pitch or amplitude) with 8 different shapes
- 16-step rhythmic sequence, syncable with external devices
Additional features:
- 3 oscillator combination diagrams with 6 different summing algorithms per node
- 2 randomization algorithms

J6 is a chord player oscillator and sequencer.
This oscillator is inspired by the Roland J-6 synthesizer, so you can check it out to understand the concept behind this oscillator.
Each note plays a different chord, and there are 100 different chord sets. These are the same as the Roland J-6 chord sets, that can be found at: https://static.roland.com/manuals/J-6_manual_v102/eng/28645807.html
It also includes:
- Mixable waveforms: saw, pulse, pulse suboscillator (with PWM for the pulse waves)
- 100 playing patterns (rhythmic, arpeggios and mixed)
- Transpose in semitones up to + or – 4 octaves
- 16-step sequencer with variable step length, for a max of 16 bars of chord playing

Proba-B is a probability sequencer based oscillator.
Use the built-in arpeggiator or record a step sequence, from 1 to 64 steps (default is 8 steps). Then assign probability values to each step, for step mute, transpose and shape change. The oscillator waveshape itself is a triangle waveform, with wave folding (shape parameter) and frequency modulation (alt parameter).
Works great with delay effects.
Extra features include:
- microtuning
- time division
- transpose, with auto minor to major scale converter.

The Volca Bass oscillator copies the “architecture” of the oscillator section of the Volca Bass.
It includes 3 oscillators, each with on/off, saw/square waveform, and pitch control up to +/-1 octave.
Includes also a slide function, octave selection (even with the ribbon), and a step sequencer, with 16 steps for notes or rest, and slide selection per step.
It features 3 memory slots for sequences, and a 4th group slot, that plays all the other 3 at the same time, each to its oscillator, paraphonically.
