101 Prophet X User’s Guide Using Sampled Instruments
Bypassing the Low-pass Filter on Sampled Instruments
By default, sampled instrument are routed through the low-pass filter
so that you can use it to shape their sound. In some cases, however, you
many not want to filter an instrument so that you can sonically separate it
from a second instrument, or from sounds created with the oscillators.
This is a great way to combine synth-type sounds with sampled sounds
and preserve the original sound of the sampled instruments without filter-
ing. Be aware that bypassing the low-pass filter on a sampled instrument
also bypasses the filter envelope for that instrument. The amp envelope
still affects the sampled instrument, but not the filter envelope settings.
To bypass the low-pass filter on an instrument:
1. Show the Sample Playback parameters in the display by pressing the
instr
1 button.
2. Press Soft Button 2 to select the
instr
1
misc
menu tab.
3. To bypass the filters for instrument 1, turn Soft Knob 4 to enable
lpf

Using Sample Stretch
The majority of the instruments on the Prophet X are multi-sampled for
greater realism. On a sampled piano, for example, samples of individual
notes are recorded up and down the keyboard as they are played soft to
hard. These samples are mapped to the corresponding key on the Prophet
X. The playback engine of the Prophet X then uses
velocity switching
to
match the appropriate sample to the appropriate velocity at which you
play.
Having said all of this, you can create many interesting sounds by turn-
ing off multi-sampled velocity switching, and instead stretching a single
sample across the entire keyboard. This can have strange and wonder-
ful effects on the sound as it is stretched far beyond the original pitch at
which it was sampled.
