| How tone is defined
The basic tone is defined by the oscillator.
Next let's take a look at the concept of tone. The tone of a sound is
defined by how it causes air to vibrate---in other words, it is defined by
the sound's waveform. With the 01AW pro, you can choose a basic
waveform from the list of those produced by the oscillator (OSC), then
process it with the filter (VDF) and WaveShaping (WS) functions to
create the final tone.
Traditional musical instruments have a fixed waveform. The 01/W
pro's oscillator (OSC) provides you with as many as 256 different
waveforms. These waveforms, which are called Multisounds, include
waveforms unique to synthesizers. Among the Multisounds which
reproduce acoustic instruments you will find variations including “loop
only” Multi-sounds, which contain the sustain portion of the sample
only, and non-transposing Multi-sounds whose pitch stays constant
regardiess of the not played on the keyboard. These Multisounds al-
low you to create highly authentic simulations of natural instruments
with relative ease.
In Program mode, select program “A13 Alto Sax” and play a few
notes. This is a realistic saxophone sound. Now display page 0 of

sound. The value that has been set for this parameter is 107:Alto
Sax. Change it to 008: HardFlute1 using the VALUE slider or the
VALUE À and V keys, then play a few notes. The saxophone has
become a flute. Next, set the value to 114---now it's a trombone! Well
then, what about number 128? Here's a Multisound that practically
shouts “synthesizer." And 134? A choir singing...

The filter changes tone over time.
You might be wondering what makes all of these Multisound wave-
forms different from one another. The answer to this question is har-
monics. A sound's waveform is ultimately defined by the harmonics
that it contains.
Try comparing the sounds produced by a violin and a flute when they
play the note A4 (the A above middle C). Both instruments produced
continuous sounds, but the sound from the violin is much brighter.
While the flute's tone is duller and more monotonous, that of the violin
is More complex and has a richer resonance. This complexity of tone
indicates that the sound of the violin is composed of a large number of
elements. By contrast, the simpler tone of the flute is composed of
fewer elements.
In fact, both of the instruments produced sounds of a much higher
pitch when they played the note A4. itis these higher sounds that are
‘called harmonics. To rephrase the explanation above, the waveform
