Eowave Persephone Monophonic Ribbon Synth

via this auction

The Eowave Persephone of course has been out for some time. The following is the product description for it from the listing:

"Eowave are rethinking instruments from the past with smart sensor technology. The result is a new innovative instrument with real analogue oscillators, a duophonic ribbon, 100% compatible with the computer environment with a USB I/O, MIDI I/O and 4 CV out.

Sensor technology now enables to recreate controls like ribbons with a new accuracy and a new duophonic process. The ribbon enables to play glissando like on a Theremin, les Ondes Martenots or a Trautonium. The addition of 1 x oscillator takes all its dimension with the new duophonic ribbon which extends the instrument sonorities spectral to play simple chords, but also enables numberless modulations, e.g. FM of one oscillator on the second one.

The Persephone markII has 2 x analogue oscillators with a waveform from triangle to saw, going from 1Hz to more than 20000Hz. An analogue resonant 12dB low-pass filter inspired from the filters from the 70s-80s enables to shape the sound. With its entire analogue audio signal path, the Persephone markII can generate notes with a continuous variable range up to 10 x octaves to create deep and resonant cello tones on the lowest notes to ultrasonic frequencies on the highest pitches. An optical modulation key will transmit the slightest vibration for expressive modulations.

16 x routing presets enable to select different routing architectures between the sound parameters and the 7 controls available (ribbon pressure, ribbon position1 & 2, key, pedals 1 & 2, LFO) for 8 destinations (lo pitch, hi pitch, filter, VCA lo, VCA hi, filter mod1, filter mod2 and VCA). 8 x presets are fixed and 8 are editable users presets configurable thru a free software. Users routing presets will be stored in the Persephone2 internal memory. This new section significantly increases the instrument control and modulation possibilities.

The A/D conversion is made with Eowave ESS DSP. This process assures a 12 bits resolution (4096 values) conversion for an accurate musical gesture. It's 100% MIDI compatible and uses USB full speed 12 MB/s. This makes the Persephone2 compatible with all MIDI compatible softwares whilst the latency is reduced at less than 1.5ms.

With a complete I/O section featuring 4 x CV outputs, 2 x pedals inputs, MIDI in & out, audio out, USB (MIDI), the Persephone markII can be turned into a powerful and unique controller to control most of your analogue or digital synths.
