Vostok Instruments
Sena is a multi-channel waveform generator driven by four precision VCO cores (Sine, Triangle, Saw and Square), four dedicated waveform modifiers, and a fully analog noise bank.
Each waveform has an independent core and frequency control. In addition, the tuning inputs of each channel are daisy-chained, allowing to create easy transpositions or detuning between them.
To maximize 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.
