Chapter 8: Creating and Editing Sounds

Page 150

Select the new stereo sound in the SOUND field. The LEFT START and

RIGHT START fields have a similar function to the SOFT START field in

the EDIT SOUND screen—they display the location within the sound that

play starts, as SECONDS.MILLISECONDS.SAMPLES. The difference is

that in this screen, there is a separate Soft Start parameter for each side.

To synchronize, you must independently set these two fields to the

desired starting sample within the sound, using one of two auto-

synchronization features. Once set, pressing <Make perm> makes your

settings permanent within the sound.

There are two synchronization methods to help you set these two fields.

Method 1: If the sound has a sharp attack such as a drum strike

If the sound has a sharp attack such as a drum strike, set the

THRESHOLD field to “1” and press <Find best>. This will set each

START field independently to the first sample that exceeds 1% of full

dynamic range. This should synchronize the audible starts of each side

to each other. If your sound has some noise before the start, you may

need to set THRESHOLD to a higher value to bypass the noise. Press

<Ply/Stp> to verify that synchronization worked and save the sound to

disk.

Method 2: If the sound doesn’t have a clear start, such as a sampled

phrase from a recorded song

If your sound doesn’t have a blank space before the intended start, then

you can’t use the <Find best> method above. In this case, you must use

the following process:

1. Listen only to the MPC60’s left output. Manually adjust the LEFT

START field until pressing <Ply/Stp> causes the sound to start

playing as close as possible to the intended start location. Use the

SECONDS sub-field (00

.000.00) to make gross adjustments then

use the MILLISECONDS sub-field (00.000

.00) to make fine

adjustments.

2. Listening only to the right output, do the same for the RIGHT START

field. Now, the sides are roughly synchronized.

3. To fine-tune the synchronization, press <InvertR>. This will perform

a process called “phase inversion” to the right side, making the right

side out-of-phase with the left. (When finished, the RIGHT PHASE

field will show “INVERT”.) In your external mixer, pan both sides

together to mono and listen to both sides. When the sides of a stereo

recording are out-of-phase and mixed together to mono, any

instruments panned to the center of the stereo recording such as

bass and lead vocal will not be heard, or will be heard at a greatly

reduced volume.

4. Fine tune either the LEFT START or RIGHT START field until

pressing <Ply/Stp> causes the greatest reduction in volume of any

center-panned sounds such as bass or lead vocal. It is best to adjust

the MILLISECONDS sub- field first (00.000

.00), then the SAMPLES

part (00.000.00

). When the volume of these center-panned

instruments is least, the sides are synchronized.
