36 Glide

Glide

Glide or portamento is a feature that has been present on synthesizers since at

least the early ‘70s. (Earlier modular synthesizers could achieve the same effect

through the use of a lag processor.) In monophonic synthesizers (or the Prophet

12 when uniSon is on), it simply causes the pitch of a note to glide up or down

from the pitch of the previously played note. When played polyphonically, the

Prophet 12 behaves in a similar fashion, except the pitch glides up or down from

the previous note played on that voice. For example, say C3 is played on voice

1 with glide on. More notes are played and cycle through voices 2 through 12.

The next time voice 1 sounds, it’s playing F#4. The pitch will glide up from C3

to F#4.

Glide is turned on and off using the

glide switch, but the glide amount must

also be set in the Oscillators section. If glide is on, but glide amount is set to

0 for all oscillators, glide has no apparent effect. Glide Amount can be set to a

different value for each of the oscillators.

Tip: To set glide amount for all oscillators simultaneously, press and briey

hold any of the oscillator select buttons until all of them are lit. Repeatedly

press Prev and next Param (Soft keys 2 & 3) until glide is displayed. Press

and hold, Hold: edit all (Soft key 1) while adjusting one of the soft knobs.

Press any oscillator button to exit.

In addition to

glide amount, there are four Glide modes—FixRate, FixRate A,

FixTime, and FixTime A—that determine how glide behaves. Turn glide on to

display and change the modes.

FixRate:

The time to transition between notes varies with the interval between

the notes; the greater the interval, the longer the transition time. The glide rate is

xed.

FixRate A:

The same as FixRate, but glide is only applied when playing legato.

That is, glide only occurs when a note is held until the next note is played. This

effectively allows glide to be turned on and off from the keyboard.

FixTime:

Glide is set to a xed time, regardless of the interval between notes.

FixTime A:

The same as FixTime, but glide only occurs when playing legato.
