CHAPTER 19. CLIP ENVELOPES 237

Try sample offset modulation with a one-bar drum loop: Make sure Beats Mode is chosen;

in the Envelopes box, choose Clip from the Device chooser and Sample Offset from the

Clip Envelope Control chooser. The Envelope Editor appears with a vertical grid overlay.

In envelope Draw Mode, set steps to non-zero values to hear the loop scrambled. What is

going on?

Imagine the audio is read out by a tape head, the position of which is modulated by the

envelope. The higher a value the envelope delivers, the farther away the tape head is from

its center position. Positive envelope values move the head towards the future, negative

values move it towards the past. Fortunately, Live performs the modulation in beats rather

than centimeters: A vertical grid line is worth a sixteenth note of offset and the modulation

can reach from plus eight sixteenths to minus eight sixteenths.

Sample offset modulation is the tool of choice for quickly creating interesting variations of

beat loops. We discourage using this technique for analytical cut-and-splice tasks; they

are much easier to perform using Live's Arrangement View, and the results can easily be

consolidated into new clips.

Repeating Steps and

Slowing Time with the

Sample Offset Envelope.

Some sample offset envelope gestures have a characteristic effect: a downward escalator

shape, for instance, effectively repeats the step at the envelope's beginning. Similarly, a

smooth ramp with a downwards slope is slowing time and can create nice slurring effects

when the slope is not quite exactly 45 degrees; try this with a 1/32 Granulation Resolution.
