Parameter: Multisample
Value Range: (varies depending on available multisamples)
This parameter lets you select the multisample you want to load for each
of the two oscillators in Sample Playback mode.
Menu: Program/Synth/Osc/Select
Parameter: Start
Value Range: 0 – 10%
When you set a Start point, you indicate how much of the initial attack
of your sample you want to include. When set to "0%," the sample will
begin playing at the beginning. At "10%," the sample will begin playing
10% into the sample and will bypass much of the natural "attack" of
your sample. Bypassing the attack of your sample results in more
"mellow" tone since much of the initial transients have been removed.
Sound designers sometimes use this parameter to control the perceived
"hardness" of the sound. For example, by mapping note velocity of the
keyboard to the start point of guitar or drum samples, the harder you
strike the keyboard, the more of the natural attack comes through
resulting in a seemingly "harder" strike (or pick, in the case of a guitar).
Conversely, as you play more softly, more of the attack is bypassed and a
mellower tone results.

About Zero-Crossing Points:

If you place your start point on a non-zero
crossing (i.e., at the top or the bottom of a
waveform) then you'll hear a click or a pop
as the sample is triggered. This click has
nothing to do with the actual sample attack,
but can be perceived as an attack. If you do
not want this sound to appear in your
sample, you can either change the start point
until it lands on (or close to) a zero-
crossing, or you can set an amplitude
envelope attack time to about 5 or 10
milliseconds and that should smooth out any
clicks or pops.
