Wavetable Osc

MOD (Wavetable A Modifier)
Each waveform in a Wavetable is stored as a single 32-bit floating-point table with 2048 samples, referred to below as
the “base table.” This corresponds to a pitch of about 25 Hz. Tables for higher pitches are generated when the
Wavetable is loaded. The Wavetable Modifier options let you change how these tables are generated, creating different-
sounding variations of the stored data.
None
: The Wavetable is loaded without alteration.
Odd Only
: This preserves only the odd harmonics. All even harmonics (2, 4, 6, etc.) are removed.
Even Only
: This preserves the fundamental and all the even harmonics. All odd harmonics (3,5,7, etc.) are removed.
The result can sound like a sine wave at the fundamental plus a waveform an octave above that.
Skip Every 3
: This removes every third harmonic (3, 6, 9, etc.).
Odd + Clip
: This combines
Odd Only
and
Hard Clip
, producing a brighter version of the Wavetable with increased
overtones and only odd harmonics.
Even + Clip
: This combines
Even Only
and
Hard Clip
, producing a brighter version of the Wavetable with increased
overtones with only even harmonics.
Skip + Clip
: This combines
Skip Every 3
and
Hard Clip
, producing a brighter version of the Wavetable with increased
overtones and with every third harmonic removed.
Low 20
: This removes all but the lowest 20 harmonics.
Low 12
: This removes all but the lowest 12 harmonics.
Organ-ize
: This emphasizes the harmonics that correspond to organ drawbars: 1 (8’), 2 (4’), 3 (2
2
/
3
’), 4 (2’), 5 (1
3
/
5
’),
6 (1
1
/
3
’), and 8 (1’). The other harmonics are still present, but greatly reduced. The result is drawbar organ sounds with
“stops” based on the Wavetable.
Vintage 8
: This quantizes to 8 bits and disables band-limiting for all but the highest notes, resulting in a brighter sound
with higher noise and significant aliasing.
Vintage 12
: This quantizes to 12 bits and disables band-limiting for all but the highest notes, resulting in a brighter
sound with moderate amounts of noise and aliasing.
4 Steps
: Quantizes the base table to 2 bits, using band-limiting to minimize aliasing (so, you’ll notice that the displayed
waveform is smoother than a simple 2-bit waveform).
8 Steps
: Quantizes the waveform to 3 bits, similar to
4 Steps
, above.
16 Steps
: Quantizes the waveform to 4 bits, similar to
4 Steps
, above.
Soft Clip:
Applies gentle soft clipping to the base table, adding overtones and increasing brightness.
Hard Clip
: Applies a gain of 3.0 and then clips the result, for a greater increase in overtones and brightness.
Infinite Clip
: Applies a ridiculous amount of gain, then clips the result.
Note that
Soft Clip, Hard Clip,
and
Infinite Clip
are very different from applying clipping to the audio output. The
timbre isn’t affected by the oscillator level or the number of voices being played, and the results are band-limited to
avoid harsh tones.
Tilt Up
: This reduces the levels of lower harmonics, and increases the levels of higher harmonics, tilted around the 12th
harmonic.
Tilt Up +
: Similar to
Tilt Up
, but more extreme.
Tilt Down
: This increases the levels of lower harmonics, and reduces the levels of higher harmonics, tilted around the
12th harmonic.
Tilt Down +
: This increases the levels of lower harmonics, and reduces the levels of higher harmonics, tilted around the
8th harmonic.
Low Boost
: Boosts the first 5 harmonics.
Low Cut
: Reduces the fundamental and first few harmonics.
Low Cut +
: Reduces the first 5 harmonics.
Muted
: Dramatically lowers the level of all harmonics above the fundamental.
Fade Out
: Crossfades successive waves in the Wavetable with 0 so that the waveform fades out to 0 as Position
increases. Use this to create decaying plucked or percussive sounds just by sweeping the Position.
Reverse
: Loads the Wavetable’s individual waves in reverse order. This is particularly useful for Wavetables which
sweep from a bright or complex sound on one end to a dark or simple sound on the other.
Gain +3 dB, Gain +6 dB, Gain -3 dB, Gain -6 dB
: Increase or decrease gain by the specified amounts. These are
particularly useful for balancing the volume between Wavetables A and B.
