EXi: AL-1 Analog Synthesizer

Program P4: 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, the ribbon, LFOs, and EGs.

Modeling vintage analog synths
OASYS 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.

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.
