The Kotelnikov is a Eurorack voltage controlled digital wavetable oscillator module with morphing features and built-in transient generator. This oscillator can generate a wide range of sounds with diverse spectral content and combine them in various proportions. Kotelnikov can also be used as a complete voice module as it features shaped timbres, an envelope generator and amplitude modulation. New to Firmware V1.1 is an Audio Bootloader utility – update the module’s waveforms using a simple utility application for Mac OS X and Windows.

Featuring 80 waveforms organised in 4 banks:
1. DRUID: Collection of Electric Druid VCDO wavetables (used with permission)
2. ATTACK: Interleaved dark/bright wavetables pairs
3. HARMONIC: Frequency-relative sinewaves
4. HD: Selected 12-bit wavetables

The Transient Generator has 3 modes: AD/AR envelope generator or resettable LFO. Total time range of 0.4µs–10s is divided into 3 subranges. This generator is internally connected with FM and WM inputs, which helps you to easily achieve fluent sounds with no wires at all.

Technical highlights:

• The sound engine sampling rate is locked to pitch and varies from 4.2 to 133 kHz, which gives very clear highs and uniform spectral content over the full range.
• The Pitch resolution is 6 cents and CV input sampling rate is 6 kHz, which gives a smooth FM-ready CV response.
• Analogue Amplitude Modulation input is bipolar, linear, rail-to-rail.


Pitch: 7 octaves range (C0-C7), 6 cents resolution
DAC: 12-bit, variable sampling rate: 4.2–133kHz
