PORTAMENTO
The Juno-66 features portamento for all play modes.
The portamento used in the Juno-66 is linear on the musical scale.
This means that when sliding from C to E, the time spent between C and D is the same than between D
and E.
Select portamento speeds
You can use the RANGE (PORTA) switch when
the arpeggiator is turned off to switch on
portamento and select its speed.
When the range switch is set to 1, portamento is
turned off.
Setting it to 2 enables fast portamento
3 slow portamento.
The exact times for ’Slow’ and ’Fast’ can be set
using midi CC 6 or the config menu 11. You can
use a midi controller to change the portamento
speed/time instantly.
Portamento and play modes
Portamento works in all play modes.
In Poly, Mono and Duo mode the last played note
is used as the start for the slide.
In Chord mode all the voices slide in paralel and
the structure of the cord is preserved.
In Polychord mode the structure is preserved if
the two chords are transpositions of each other
(e.g. two minor chords.)
Otherwise an extra algorithm makes sure that the
lowest note of the first chord slides to the lowest
of the second chord and so on. This is to make
sure that even here a portamento sounds natural
and you do not end up with musically unpleasant
sounds while sliding.
Constant Time and Constant Speed
The Juno-66 features two portamento modes:
’Constant Time’ and ’Con- stant Speed’.
In ’Constant time’ mode it always takes the same
amount of time to slide from one note to the next
no matter how far they are apart.
In ’Constant speed’ mode it takes a certain
amount of time to slide from one semitone to the
next, the overall time for the slide changes with
the distance of the notes played. The modes can
be selected in the config menu 11.
’Constant time’ is set as default.
