Using A Sound File

SP-

The SP-12 Librarian’s sound files contain all the sample

data sent by the SP-12, as well as the names and

categories for each of the samples in that file.

Sound files can be opened by using the File menu’s

Open

command. Each open sound file is represented by a single window

that can be viewed in two different ways, as illustrated below:

A typical sound file, shown with

View Names

A typical sound file, shown with

View All

View

A sound file’s view can be changed by using the Window menu’s

View Names

command, or

View All

command. These commands

apply only to the active window, which must be a sound file. Each

sound file can have its own view. A check mark ( ) will appear to the

left of

View Names

View All

, depending on the way the window is

viewed.

Each sound file remembers the way it was displayed when you quit

the SP-12 Librarian or when the sound file is closed. The next time

you open that sound file, it will be displayed with the same view.

Identifying RAM Samples

The SP-12 has two different types of samples: RAM and ROM. RAM

samples (Random Access Memory), are the samples that are

changeable and are saved and loaded by the SP-12 Librarian. ROM

samples (Read-Only Memory) are always in the SP-12 and cannot

be changed or erased, such as the “Rim” and “Cowbell.”

A RAM sample can be played by any pad on the SP-12, even those

that normally have ROM samples. So a need arises to identify where

the samples are located. Below, is a bank of sounds as seen when a

sound file is in

Sample

Flag

Wherever a RAM sample is stored, a “Sample Flag” (a dark

rectangle) appears to the right of the sample’s location. In the

example above, the following pads contain RAM samples: Bass 1,

Bass 2, Snare 1, and Snare 2. The remaining locations (El. Snare 1,

El. Snare 2, Rim, and Cowbell) retain their original ROM sounds.

Note: If you copy a RAM sample to another location and you don’t

delete the original sample, you will see two sample flags; one for the

original sample and one for the copy. The SP-12 is smart enough to

do this without consuming additional memory for the copied sound.

Sound File Changes

Changes made to a sound file by using the SP-12 Librarian

application are stored only within that file. They are not automatically

sent to the SP-12. For example, if you change a sound’s tuning value

on the sound window, the SP-12 must first load that sound (or the

entire sound file) before the change can be heard on the SP-12.

Naming Sounds

Sounds can be named in either view:

View Names

View All

. Use

standard Macintosh text editing rules to type and change names. The

one thing that differs from most other Macintosh applications is that

the SP-12 Librarian’s fields are “length limited.” This means the

Name field accepts a maximum of 30 characters, including spaces.

The RAM sample names will eventually be used to compile the

Sound Catalog, so be descriptive. Don’t bother naming ROM sounds

(those without a sample flag), since they play the sound that is

indicated by their location (ie: Bass 1).

For reasons of consistency, you should adopt standard conventions

for naming sounds, such as mixed case letters (“Hi-Hat”) or capitals

(“HI-HAT”).

Categorizing Sounds

Sounds can be categorized only when the window is in

View All

. Use

standard Macintosh text editing rules to type and change a sound’s

category. The one thing that differs from most other Macintosh

applications is that the SP-12 Librarian’s fields are “length limited.”

This means the Category field accepts a maximum of 12 characters,

including spaces.

The RAM sample’s categories will eventually be used to compile the

Sound Catalog, so be descriptive. Don’t bother categorizing ROM

sounds (those without a sample flag), since they will not appear in

the Sound Catalog.

Sample classification can be simplified by creating a list of standard

categories. This list is created by using the Catalog menu’s
