16 Oscillators

Dave Smith Instruments

Frequency Modulation (FM): 0…127—

Allows one oscillator—called the

modulator, for the purposes of FM synthesis—to modulate the frequency of

another oscillator—called the carrier. The arrows between 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, turn-

ing 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 shortcut. In

fact, you can route any oscillator to another using the modulation matrix. See

Modulation on page 32 for more information.

Amplitude Modulation (AM): 0…127—

As with FM, AM uses the oscillators

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 congured 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

glide switch must be on to hear the effect of glide amount. For a detailed expla-

nation, see Glide on page 36.

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.

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 oscilla-

tor pitched one octave below oscillator 1.
