17 PROTON User Manual
3. Oscillators
Your Proton has two analog VCOs, whose pitch can be controlled
by MIDI (5-pin DIN or USB) or from a suitable CV source in the
range -5 V to +5 V. The VCOs are capable of producing frequencies
between 0.7 Hz to 50 kHz. Each VCO has its own controls for
tuning, range, shape, pulse width and sub mix. In addition there is
an Oscillator mix control and buttons to select Oscillator sync and
paraphonic mode.
3.1 Tuning
The two VCOs can be individually tuned by 13 semitones up or
down.
3.2 Range
The two VCOs can have their range set to either 32’, 16’ or 8’, which
is indicated by the LEDs on the front panel. The ranges can be
stepped through using the range buttons, from 8’ down to 32’.
When all three LEDs are let on either VCO it is in ten octave mode
and will respond to the full note range.
