FEATURES

PC Editor & Automation

Rythmos Syn extends beyond its physical controls with a dedicated PC-based sound design and performance editor, providing a visual environment for sound creation, sequencing and live performance.

The interface brings the synthesiser's oscillators, filters, envelopes and modulation controls together on screen, making it easier to explore complex sounds, adjust parameters and understand how the sound engine works.

A programmable parameter automation system is also in development, designed to enable timed parameter changes, repeating sweeps and stepped modulation. The goal is to create evolving sounds and sequences without having to make every adjustment manually.

Designed to complement rather than replace the hardware, the PC editor offers another way to explore and control Rythmos Syn.

Description

Steps, Oscillators and harmonics

This programmable electronic step synthesiser contains the core parts of a modular synth setup. There is a fundamental variable shape frequency oscillator that is adjustable from 27.5Hz A0 to 3951.1Hz B7. Seven additional oscillators provide individually adjustable harmonic and sub-harmonic layers, with tuning and mixing controls for shaping complex tones.

Effects and filters

Eight oscillators feed a shared mixer before splitting into two parallel filter paths: a State Variable Filter (SVF) and a Ladder Filter. The SVF supports LFO and DC envelope cutoff modulation, while the Ladder Filter includes LFO modulation, filter envelope control and Bass Drive. Both paths are mixed together before the final output ADSR envelope, enabling layered tones and evolving rhythmic textures.

Playing patterns

Each of the 32 steps can be switched on or off and assigned individual frequencies or notes. A reset count sets the sequence length, while playback modes include forwards, backwards, stepped variations and other rhythmic playback patterns. Tempo can be adjusted internally or controlled externally using a 5V CV / gate input.

Unlike traditional single-filter synthesizers, Rythmos Syn processes sound through multiple parallel paths simultaneously, creating richer textures, deeper movement and more complex evolving timbres.

Memories

There are 6 instant play / save memories and a total of 6*6 = 36 pattern memories that save all settings.

Affordable modular-style sound design

Rythmos Syn brings modular-style sound exploration into one hands-on instrument. DIY kit and enclosure options are being explored while the hardware and firmware continue to develop. Pricing and availability have not yet been finalised.

Great for professionals and hobby musicians

The modular design allows the user to craft and create a huge range of beat patterns and apply filter and effects during playback. The circular design and custom features make it quite unique and stylish and maybe a bit retro. It is ideal for chiptune creators, techno producers, experimental sound designers, hobbyists and professional musicians.
