SAMPLING YOUR OWN SOUNDS

4H MODIFYING A SAMPLE VIA TRUNCATION AND LOOP

Truncation shortens a Voice’s length by trimming off parts of the beginning and/or end. This allows you to cut off unneeded portions of a Voice to save memory, change instrument characteristics (i.e. remove the attack from a plucked string note), cut off a long decay (which is great for simulating noise- gated reverb effects on drums), or isolate a particular section of a sample.

As mentioned in the introduction, the SP-12’s standard memory capacity is 1.2 seconds. Since each second requires 27,500 samples, this works out to a total available memory space of 33,000 samples. All truncation and looping times are referenced to samples, not seconds. Example: If you truncate the beginning (start) of a sound by 2,750 samples, you have cut 1/10th of a second from the start of the sound (27,500 samples 1 second, so 2,750 samples = 1/10th of a second).

To truncate a sound:

1.It is good practice to set Sliders #1 and #2 all the way down, and Sliders #3 and #4 all the way up, before beginning the truncation process.

2.Activate the SET-UP module and key in 19. The display’s top line will show the User Sound to be truncated. If this is the desired User Sound, press ENTER. If not, key in the desired User Sound with the keypad and then press

ENTER.

3.The display’s top line will now show the Start point (which defaults to 00000) and the User Sound being truncated. The display’s bottom line will show the End point of the sample (which defaults to the sample length) and Loop Length (which defaults to NONE). Example: If the End display shows 27500, then the sample is exactly one second long.

4.Slider #1 gives coarse control over the amount of start truncation, while Slider #2 gives fine control. Moving the sliders upwards increases the amount of truncation.

Example:

Adjusting these sliders so that the bottom line indicates E=2750 means that you have cut 1/10th of a second from the beginning of the sample.

Note that you cannot truncate a sound one sample at a time, but rather, in groups of samples (even with the fine truncation slider).

5.Slider #3 gives coarse control over end truncation, while Slider #11 gives fine control. Moving the sliders downwards increases the amount of truncation.

Example: With a 27500 sample length sound, setting these sliders so that E=13750 means that the end point now occurs halfway through the sample (27500 divided by 2 = 13750).

As with start truncation, samples are truncated in groups rather than one at a time, even with the fine truncation slider. As you change truncation, press the appropriate Play button to hear the results.
