The Sena is a fantastic entry point into modular synthesis, providing four distinct CEM3340-based oscillators with useful shaping controls. It’s ideal for sound designers, experimental musicians, and those wanting a solid foundation of analog oscillators without a massive investment. The noise bank is a surprisingly useful bonus, too.
Product Description
- Vostok Instruments Sena
- Eurorack Module
- 4-Channel oscillator and noise source
- 4 Separate oscillators based on the CEM3340 chip and with a different sound spectrum per channel
- Channel 1: Sine waveform with two-stage wave folder and fold control with CV input
- Channel 2: Triangle waveform with waveshaper and shape control with CV input
- Channel 3: Saw rate waveform with phase shifting and phase control with CV input
- Channel 4: Square waveform with adjustable pulse width and PWM controller with CV input
- Per channel: Tuning control with selectable tuning range (6 octaves / 2 semitones)
- pitch/FM input
- switchable LFO mode and waveform output
- Noise bank with outputs for white
- pink
- blue and brown noise
- Current requirement: 130 mA (+12 V) / 130 mA (-12 V)
- Width: 14 HP
- Depth: 30 mm
PROS
- • CEM3340 oscillators deliver a classic, warm analog character instantly familiar to many.
- • Four distinct waveforms offer a wide palette of sonic possibilities, avoiding predictable tones.
- • The per-channel CV control over wave shaping adds significant modulation depth and expressiveness.
- • Noise bank with varied colors expands sound design options beyond simple oscillator tones.
CONS
- • 14HP footprint can be limiting for smaller Eurorack cases or patch complexity.
- • CEM3340 chips, while great, aren't the most cutting-edge; expect a vintage vibe.
- • Limited modulation options beyond the included CV inputs; requires further modules.

Frequently Asked Questions
It’s a simpler, two-stage implementation; it adds warmth and subtle distortion, but lacks the extreme complexity of a full wavefolding module.
Absolutely! Each oscillator has a tuning control, allowing for basic VCO functionality, though you'll lose the shaping modulation.
No, the noise outputs are fixed; they provide the standard noise color profiles without level or EQ adjustments.
