16 Oscillators
Dave Smith Instruments
the oscillator select buttons show the modulator/carrier relationship
between the oscillators, as does the following table.
Carrier
Modulator
Oscillator 1
Oscillator 2
Oscillator 2
Oscillator 3
Oscillator 3
Oscillator 4
Oscillator 4
Oscillator 1
Turning up FM for oscillator 1 causes it to be modulated by oscillator 2,
turning up FM for oscillator 2 causes it to be modulated by oscillator 3,
and so on.
Note:
The indicated order of modulation is really just a handy short-
cut. In fact, you can route any oscillator to another using the modula-
tion matrix. See Modulation on page 32 for more information.
Amplitude Modulation (AM): 0…127—
As with FM, AM uses the oscil-
lators as carrier/modulator pairs. But with AM, the modulator modulates
the carrier’s amplitude, not its frequency. As with FM, any oscillator
routing combination can be configured using the modulation matrix.
Glide Amount: 0...127
—Sets the oscillator glide (portamento) amount.
Glide can be set independently for each oscillator. Low values are
shorter/faster. The g
liDe
switch must be on to hear the effect of g
liDe
a
moUnt
. For a detailed explanation, see Glide on page 36.
Tip:
To set g
liDe
a
moUnt
for all oscillators simultaneously, press
and briefly hold any of the oscillator select buttons until all of them
are lit. Then adjust g
liDe
a
moUnt
. Press any oscillator select button
to exit.
Slop: 0…127—
Adds random detuning to the oscillator to emulate the
tuning instability of voltage controlled analog oscillators, from subtle,
barely perceptible amounts to wildly out of tune.
Oscillator 1 Sub Octave: 0…127—
Controls the level of a sine wave
oscillator pitched one octave below oscillator 1.
