Adjusting The Sample Playback Length - Alesis GT Reference Manual

Notes
¥ Because of the nature of sampling, the timing of the sample as well as
the pitch will change the farther away from the base note from which
it is transposed, with the higher notes sounding like ÒmunchkinsÓ
and the lower notes like Ògiants.Ó This is a normal phenomena that
occurs during sample playback.
¥ The pitch of the sample will follow within a 2 octave range and will
loop back into the range if any note information falls outside of the 2
octave range. For instance, if the base note has been selected to note
number 60 (Middle C or C3) and you play note number 84 (C5), the
sample pitch will be triggered 1 octave higher than the bass (C4).

Adjusting the Sample Playback Length

In any playback mode it is possible to adjust the sample playback length
to either ignore unwanted sampled material or Òdead air,Ó or to make a
loop more musical. To do this:
1. Assuming the DELAY module is selected, use the PAGE buttons to
select the display that says:
This page determines the point from which the sample plays back.
2. Use the VALUE buttons to select the desired Start time. The start can
be anywhere in the sample in 10 millisecond steps. Moving the
sample start maintains the loop length unless the sample end moves
past the loop end point. In this case, the loop will end at the actual
sample end regardless of the loop duration. However, the duration
value will remain intact, and will retake effect if the loop start is
moved forward enough to allow the complete loop length.
3. Use the PAGE buttons to select the display that says:
SAMPLE START:
0 .00 SECONDS
SAMPLE LENGTH:
1 .55 SECONDS
