OSCILLATOR SECTION
The lower parameter is “Unison detune”. In this case with a value of 8.
This parameter determines the relative detuning of voices when the Unison mode above is active. Use the lower Data knob to
adjust this parameter. When this parameter is set to low values only small shifts in tuning are applied to the different voices. When
this parameter is set to high values only larger shifts in tuning are applied to the different voices.The range of this parameter is 000
to 127. This parameter is memorised with a Program.
Page 5 looks like so:
The higher parameter is “VCO drift”. In this case with a value of 64.
This parameter determines the how the tuning of all the oscillators behave. Use the higher Data knob to adjust this parameter.
When this parameter is set 000 the tuning between the oscillators is perfect. This is the case on “DCO” ( Digitally Controlled
Oscillator ) synthesisers such as the Roland Juno 106 or Juno 60. Tuning this parameter up gradually increases the classic “VCO”
( Voltage Controlled Oscillator ) characteristics. At relatively low levels this parameter is similar to a quality VCO synth with all its
oscillators tuned up. At 127 the oscillators are quite out of tune & it sounds like a VCO synth in need of a service! The range of this
parameter is 000 to 127. This parameter is memorised with a Program.
The lower parameter is “Osc start phase”. In this case with a value of 000.
This parameter determines the phase at which the oscillators start at when a key is pressed. Use the lower Data knob to adjust this
parameter. When this parameter is set to 000 the start phase of the oscillators is at 0˚. When set to 32 the start phase of the oscil-
lators is 90˚. When set to 64 the start phase of the oscillators is 180˚. When set to 96 the start phase of the oscillators is 270˚ &
when set to 127 the start phase of the oscillators is approx 355˚. The phase is smoothly adjustable from 0˚ to nearly 360˚ with this
parameter. The range of this parameter is 000 to 127. This parameter is memorised with a Program.
This parameter will not have any effect at all if the Osc mode parameter on page 2 of this menu is set to Ensemble as this makes
all oscillators freewheel, in which case no phase control is operational.
This parameter is useful in the creation of “Percussive” sounds & drums when set to either 32 (= 90˚) or 96. (= 270˚)
Portamento - Knob
This knob adjusts the Portamento effect on the currently selected Program. Fully anticlockwise no Portamento is heard. Turning the
knob clockwise brings in the Portamento effect & notes will smoothly glide from one pitch to the next. The range of this parameter
is 000 to 127. This parameter is memorised with Programs.
