This chapter introduces you to the eight-voice polyphonic
ES P (ES Poly) synthesizer.
Functionally, (despite its velocity sensitivity) this flexible synthesizer is somewhat
reminiscent of the affordable polyphonic synthesizers produced by the leading
Japanese manufacturers in the 1980s: Its design is easy to understand, it is capable of
producing lots of useful musical sounds, and you may be hard-pressed to make sounds
with it that can’t be used in at least some musical style. The creation of classic analog
synthesizer brass sounds are just one of its many strengths. All ES P parameters are
discussed in the following section.
 4, 8, 16 buttons: The 4, 8, and 16 buttons determine the ES Ps octave transposition.
 Waveform faders: The faders on the left side of the panel allow you to mix several
waveforms, output by the oscillators of the ES P. In addition to triangular, sawtooth,
and rectangular waves, the rectangular waves of two sub-oscillators are also
available. One of these is one octave lower than the main oscillators, and the other,
two octaves lower. The pulse width of all rectangular waves is 50%. The right-most
fader adds white noise to the mix. This is the raw material for classic synthesizer
sound effects, such as ocean waves, wind, and helicopters.
 Vib/Wah knob: The ES P features an LFO which can either modulate the frequency of
the oscillators (resulting in a vibrato), or the cutoff frequency of the dynamic lowpass
filter (resulting in a wah wah effect). Turn the control to the left in order to set a
vibrato, or to the right to cyclically modulate the filter.
