Module: DIGITAL PROCESSING 2 Function: SET LOOP START and LOOP LENGTH POINTS
“Looping” lets you mark off a section (called a loop) of a Voice with a Start point and loop Length
(see Fig. DIGPROC-2). When you press a key, the Voice plays normally until it reaches the end of
the loop. It then jumps back to the Start point and re-plays through the loop. Upon reaching the
loop end, it again replays the loop. This looping process continues for as long as the key is
pressed. Fig. DIGPROC-3 indicates a typical looping action.
Note:
DIGITAL PROCESSING 4 controls three aspects of looping: loop on/off,
forwards/backwards, and loop in release. Refer to this section for specifics. Note also that
Emax offers two loops (see Fig. DIGPROC-4), each of which can loop a different portion
of the signal. The Sustain Loop Is operative when the key Is down, and the Release Loop
Is operative In the release phase, when the key Is up.
Applications: Looping provides “infinite sustain” effects, extends short samples, and if the loop time is
rhythmically related to a composition, produces interesting rhythmic effects.
1. Activate
DIGITAL PROCESSING 2 . The display shows:
The six digits under Start indicate, in number of sample points, the Start of the Loop in relation to the
beginning of the Voice. A higher number moves the Start point closer to the end of the sample.
Example : If Start reads 028000, the Start point is located one second (at the nominal sample rate)
into the sample (see Fig. DIGPROC-5). The six digits under Length indicate the Loop Length in
number of sample points. A higher number increases the loop Length.
Example: If L reads L028000, the loop is one second long (see Fig. DIGPROC-6) at the nominal
sample rate. Select the parameter to adjust with the cursor buttons. Adjust the coarse value with the
data slider and fine value with the increment and decrement keys, or enter a six-digit number.
2. Remember -- L sets the Length, not the end point, of the loop.
Example: Consider the loop in Fig. DIGPROC-7. When S moves, the loop end point (as determined
by the loop Length) moves in tandem with S.
After finding a good loop, press ENTER .
Hint: If the loop Length is at maximum (as occurs when you first call up a Voice for looping), you
cannot set a new S point since that would force the loop to “run out of sample” (see Fig.
DIGPROC-8). Shorten the Length before moving the S point.
