EXi: AL-1 Analog Synthesizer

PROGRAM > AL-1: OSC/Pitch
These pages control the most basic elements of AL-1’s
sounds: the waveforms that the oscillators play, and the pitch
at which it plays them. For instance, you can:
• Select the waveforms for Oscillator 1, Oscillator 2, and
the Sub-Oscillator.
• Set the basic pitch of the sound, including the octave,
fine tuning, and so on.
• Control pitch modulation from a wide variety of sources,
such as JSX, LFOs, and EGs.

Modeling vintage analog synths
NAUTILUS and the AL-1 provide a range of features for
modeling vintage analog synths. Instead of simply providing
fixed presets to choose between, there are separate
parameters for individual synth characteristics–which means
that you can mix and match as desired, for an even broader
timbral palette.
For more information on modeling specific aspects of
vintage synths, see the references below.
• Oscillator timbre: see “Edge” on page 146
• Oscillator pitch: see “Randomizing frequency for an
analog feel” on page 146
• Unison pitch: see “Thickness” on page 132

Waveform
Waveform [Saw, Pulse, Saw/Pulse, Double Saw,
Detuned Saw 1, Detuned Saw 2,
Triangle, Square/Triangle]
This selects the waveform for Oscillator 1, and will also
affect the behavior of the Wave Morph and Pulse
Width/Phase/Detune parameters, below.
Saw produces a sawtooth wave–the traditional buzzy analog
synth sound.
Pulse produces a square wave with variable pulse width, as
controlled by the Pulse Width parameter below.
Saw/Pulse creates both of the waveforms at the same time.
You can crossfade between the two using the Wave Morph
parameter, below.
Double Saw produces two sawtooth waveforms
simultaneously. You can adjust the phase of the second
sawtooth using the aptly-named Phase parameter, below,
and adjust its volume with the Wave Morph parameter.
Detuned Saw 1 produces two detuned sawtooth waveforms
simultaneously. Detune controls the amount of detuning,
and Wave Morph adjusts the volume of the second
sawtooth.
