Description
Sena is a multi-channel VCO built around the 3340 oscillator core, found in classic synths like the SH-101, OB-Xa, and Jupiter-6 and features a noise bank for added spice.
The Sena features four independent channels for each of the four waveforms, sine, triangle, saw, and square, giving you surgical precision when making adjustments.
Each channel has its own V/Oct input, Frequency control, output, and unique wave shaping – the Sine chanel has a two-stage folder, Triangle has a trapezoid shaper, Saw features a phase modulator, and the Square has a PWM. To complement this vast range of tones, Sena also comes equipped with an noise bank with four different types of noise outputs: White, Pink, Brown, and Blue, each with their own analog characteristics.
Features:
- Fully analog VCO circuits: Sine, Triangle, Saw and Square
- 1V/Oct pitch tracking over eight octaves
- Dedicated CV controlled Wave Modifier on each oscillator
- Daisy-chained Freq inputs with onboard buffers
- Selectable LFO mode per channel
- Analog noise bank with White, Pink, Blue and Brown circuits
