CHAPTER 22. LIVE INSTRUMENT REFERENCE 298

22.2.2 Sample Controls

Simpler plays a specic region or loop of the sample, as determined by a group of sample

controls.

The Start and Length controls work together to specify where Simpler begins and ends its

sweep of the sample. As the name implies, Start denes where sample playback starts.

The sample will play for the length dened by the Length parameter. Both parameters are

dened as a percentage of the whole region, so setting start to 25 percent and length to

50 percent, for example, will start playback 1/4 of the way through the sample and stop

playback at the 3/4 mark (using 50 percent of the sample).

Samples are played by Simpler as one-shots or as loops, depending on whether or not the

Loop switch is active. When looping is active, the Loop control dictates the length of the

loop, starting from the end of the playing sample. Simpler will play the rst instance of a

looped sample beginning with the Start point, then continue playing only the loop region.

When the sample's start or end points are moved, Simpler will try to preserve the loop length

for as long as possible by automatically adjusting the Start, Loop and Length settings.

It is possible for glitches or pops to occur between a looped sample's start and end points

due to the discontinuity in wavefor m amplitude (i.e., the sample's loudness). The Snap

switch will help mitigate these by forcing Simpler's loop markers to snap to zero-crossing

points in the sample (points where the amplitude is zero). Note: Snapping is based on the

left channel of stereo samples. It is therefore still possible, even with Snap activated, to

encounter glitches with stereo samples.

The transition from loop end to loop start can be smoothed with the Fade control, which

crossfades the two points. This method is especially useful when working with long, textural

samples. By default, Simpler uses constant-power fades. But by turning off Use Constant

Power Fade for Loops in the

(PC) /

Ctrl

(Mac) context menu, you can enable linear

crossfades.

22.2.3 Zoom

Quite often, one starts with a longer region of a sample and ends up using only a small part

of it. Simpler's Sample view can be zoomed and panned just as in other parts of Live  drag
