Proteo

Constantly Evolving Stereo Oscillator

> The name, indeed, comes from the ancient Greek mythology, since Proteo was a shapeshifter that can assume whatever shapes he prefers. In this way, our Proteo, has not a precise sound on its own but a clever mechanism that permits to acquire and transform every signal into waveforms. What if you can use your envelopes, LFOs or any other signal as a sound source?

Proteo is our new take on west-coast style additive oscillators,

But what sets apart from other oscillators?
What's very different in Proteo is its internal pseudo-tape recorder, capable of continuously acquire and transform any external signal into waveforms, and morph to them from a basic sine.

In Proteo, waveforms are not a static digital representation of a sound, they can continuously evolve in a very organic way, and tape loop time is a fundamental factor:

changing it will drastically affect the resulting output even with the same sources at the inputs.
Slowing down the time will capture a bigger portion of the incoming source with more harmonics as a result, increasing it allows to capture up to low audio rate signals or really small fragments of signal.

Exploring the interaction between Proteo, the sources and the time will force you to change your mind on how sounds and harmonics can be generated:

visualizing how different shapes can sound and looking for new sources to generate YOUR waveform is the fundamental idea behind Proteo.

Proteo is also stereo.
Thanks to the Span knob you can easily detune one oscillator from the other to create really nice stereo effects.
Beside the common pitch the two oscillators have independent acquisition paths and morph controls, each one can emit different waveform.

HOW DOES IT WORK?
By default, Proteo emits two sine waves at its outputs.

The left section is composed by a time based acquiring path with two separate inputs,
insert here any source you want to acquire (CV, gate or low audio).

Each input has its own preamp, which can attenuate or double the amplitude of the incoming signal.

Acquisition time is the speed of the digital tape recorder, from 2.5 seconds to 1kHz.
An external input with a dedicated attenuverter will let you modulate it from outside.

Morph, controls the interpolation between the sine waves and the acquired waveforms.

The final waveform can be seen on the two small oscilloscopes, one for each oscillator.

Acquired waveforms can also locked independently with the two freeze buttons or with an external signal trough the freeze gate ins.

The two oscillators are tied together to the same V/oct and pitch, which can be changed with the freq knob.

Span, controls the distances between the left and right parts by detuning the right one from 4 octave below to 1 one octave higher.
