Oscillators

Osc Slop: 0...5—

The amount of random oscillator frequency tuning slop. The

analog oscillators in Tempest are very accurate, and will not drift. This works

great for accurate sounds, and allows precise de-tuning. o

SCillatoR

loP

allows

subtle amounts of frequency drift. For larger amounts, use a random LFO.

Glide Mode: FixRate, FixRate A, FixTime, FixTime A—

Determines how the

oscillators respond when g

lide

is on.

•

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 fixed.

•

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 just by playing

staccato or legato.

•

FixTime:

Glide is set to a fixed time, regardless of the interval between

notes.

•

FixTime A:

The same as FixTime, but glide only occurs when playing

legato.

Key Follow: Off, On—

Turns keyboard tracking off or on for oscillator 1 or 2.

When off, the oscillator plays at its base pitch and will not transpose when played

from the pads or via MIDI.

Wave Reset: Off, On—

When off, the oscillator is free-running and may be

at any point in its cycle when the voice is gated on. Most analog synthesizers

behave this way. The most noticeable effect is that the attack may vary slightly

at very fast settings, adding a slight, variable click that can be desirable for some

sounds. When w

ave

eSet

is on, the oscillator is restarted—reset to the zero

crossing at the start of its cycle—every time a note is gated on.
