How Sampling mode is organized
In Sampling mode
• An external audio signal from an external audio
device or microphone connected to the AUDIO
INPUT 1 and 2 jacks is passed through an analog/
digital convertor, and recorded (sampled).

• You can edit the waveform and loop settings etc. of
sample data that you sampled or that you loaded
from a floppy disk, CD-ROM etc., in Disk mode.

• You can assign samples to the keyboard to create a
multisample. These samples and multisamples can
be easily converted to a program using the Utility
“Conv. To Program,” and these programs can be
used immediately in a combination or multi.

Sampling frequency and bit resolution
As shown in the diagram, sampling reads the level of
the analog signal at fixed intervals along the time axis,
and stores the levels in memory as digital data.
the analog signal at fixed intervals along the time axis,
and stores the levels in memory as digital data.
The “fixed intervals” mentioned above are generally
expressed as the “sampling frequency.” 48 kHz (kilo-
hertz) means that sampling is performed 48,000 times
each second, and that the interval is 1 (second)/48,000
(times) = approximately 0.00002083 (seconds) =
approximately 0.02083 mS (millisecond).
