Sampler functions

Under the "

monitor" parameter is a message telling you how much memory is

free, both as a number of 16-bit words, and as a percentage of total memory

available. If you have followed the instructions so far, this will read

"1048064=100%". 1048064 words are equal to 2 megabytes for obscure

computer-based reasons which are too tedious to explain here. These values cannot

be changed.

sample name

If you want to select or enter an existing sample name for re-recording, you can do it here

with the DATA knob or the

NAME button and letter/number buttons. This field will not

allow you to rename the sample.

bandwidth

Either 10kHz or 20kHz. These figures refer to the audio bandwidth of the completed

sample - not the sampling frequency, which is either 44.1kHz or 22.05kHz (for the

technically minded, Nyquist's theorem' applies here). Sampling at the lower frequency

will give you more memory, but filter out the top octave. For some sampled sounds this

may not matter - like the choice between stereo and mono, it's up to you, and the final use

of your sample.

orig. pitch

(original pitch) - default is C_

3. Incidentally, if you prefer to work with MIDI note

numbers rather than key names, press the

REC1 key again to display the MIDI note

number. This feature is available in all pages which use note names and note numbers.

Make this parameter equal to the pitch of the sample source. For unpitched sounds, of

course, this can be any value.

record tim:

(recording time). Once the S1000 starts sampling it

will carry on until it runs to the end of

the time set here (you can set this field to one-hundredth of a second precision). As you

alter the value here, you will see the figures underneath change, showing you the amount

of memory that this time represents, in bytes, and as a percentage of total memory

available.

SOFT KEYS

SLCT

The SLCT button takes you back to the opening page of the EDIT SAMPLE section. Any

soft key labelled in this way will usually take you back one level of page.

REC1

Pressing this button toggles between MIDI note number and key name display.

REC2

Enters the second recording page -- where the actual recording of a sample takes place.

1 Nyquist's theorem (sometimes known as Shannon's sampling theorem) is a mathematical statement that a

digital-analog or anaor -digital conversion process needs a digital data rate of more than twice the highest analog

frequency in er to convert data with no distortion. The nature of the low-pass filtering employed affects the exact

ratio.
