Oscillator 1/2

Overview
Osc 1 and Osc 2 can each play either a single Wavetable, a modulatable blend of two Wavetables, or a Multisample.
modwave native ships with over 200 Wavetables, and you can also import your own. The sound of the Wavetables can
be changed in different ways. Wavetable Modifiers change the way that the tables are generated at load time, resulting
in subtle to extreme changes in timbre. Morph Types change the way that the Wavetables are played, and can be
modulated in real-time from Envelopes, LFOs, and so on.
Oscillator Mode
[A, A/B, Sample]
This three-way switch controls the basic capabilities of the Oscillator.
A: The Oscillator will play a single Wavetable.
A/B: The Oscillator will play a blend of two Wavetables, A and B. Because the Wavetables are phase-synchronous,
the result is truly a blend between the two shapes, rather than a simple layering effect. A/B Blend lets you control the
balance between the two.
Sample: The Oscillator will play a Multisample.
A and A/B Modes

Listening to the Wavetables
When auditioning Wavetables, play lower-pitched notes. The lower the pitch, the more clearly you'll hear all of the high
harmonics.
By default, the Osc 1 and Osc 2 Envelopes modulate Position; this sweeps the Wavetables for their respective
oscillators. Attack sweeps forward in the Wavetable, and Decay sweeps backwards; the Sustain level determines the
resting point. Try both fast and slow envelope times for both Attack and Decay—even 10 or more seconds may be
useful for particularly complex Wavetables!
Adjust the amount of modulation using Env Intensity. Sometimes, you may want the intensity to be at its maximum;
other times, especially with more complex Wavetables, much smaller amounts of modulation may be better.
Some Wavetables may be optimized for use with an LFO, to repeatedly sweep Position back and forth. To set this up:
1. Set an LFO to use a Triangle wave.
2. Drag the LFO to the Position knob, to create a modulation routing.
3. Set Position to 50, and LFO Modulation Intensity to 100.
Mod A (Wavetable A Modifier)
[None... Gain -6 dB]
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.
