Sena is a compact multi-channel analog waveform generator powered by four high-quality oscillators and noise generators.

To maximise stability and tracking accuracy, every channel is designed around the famous 3340 oscillator core, present in many legendary synths like the Roland SH-101 and Jupiter-6, Oberheim OB-Xa, and the Sequential Prophet-5.

Each core features a dedicated voltage-controlled modifier selected to enhance the unique timbral capabilities of its waveforms and create a vast array of sounds with just a few cables.

The addition of a complete analog Noise Bank makes Sena a super powerful and compact sound source. A cornerstone for any Eurorack setup.
