Akai S950 Operator's Manual page 32

Move to Page 14 using the 'page down' button and the display will read:
As with crossfade looping and splice crossfade, it is necessary to create a new
sample so move the cursor one position to the right by pressing the 'cursor >'
button and enter a new name in the usual way and hit the ENT button. Now move
the cursor one more position right and select the' percentage by which you want
to stretch or compress a sample.
Note:. as you have to create a new, longer sample it is quite feasible that
you may not have enough memory. Ensure, then, that if you are stretching a
sample, particularly
accommodate it. If you do not have enough memory, the display will tell you.
The next field allows you to set what is known as a D-TIME. When you stretch a
sample, you are basically instructing the S950's computer to play the sample
and, in order to lengthen it, to fill it in with bits of information thereby
making it longer. Compressing a sample removes certain bits of information so
making it shorter.
sometimes sound slightly metallic. The D-TIME function smooths things out
allowing you to suppress this effect. Longer, D-TIME values will give the
sample a slight tremolo effect whilst shorter D-TIME values give rise to the
metallic effect. Select a D-TIME value as you think appropriate. Of course,
this only happens on extreme stretch or compression percentages. To further
assist you in selecting a suitable D-TIME, there is an AUTO-D function which,
like autoloop, gets the S950 to select a suitable D-TIME value.
The next field, Monl/Po12, allows you to select whether the sample you are
stretching or compressing is a monophonic or polyphonic sample. The 'Monl'
setting is more suitable for lengthening a single tone whilst the 'Po12' is
better suited to lengthening polyphonic samples such as backing vocals, drum
loops, etc.. It is best just to experiment with the various options until you
arrive at the best sounding result.
To change the data in any of these fields, move the cursor to the appropriate
position and change the value displayed using the numeric keypad. When you
have done this, move the cursor to the 'DO' field and press ENT and the S950
will pause for a short while whilst it calculates the new sample (the EDIT
SAMPLE light will remain lit). When this is done (i.e. when the EDIT SAMPLE
light begins to flash again), hit EDIT SAMPLE and select the new sample on
Page 01. Play a note on the keyboard or hit the PB button to hear- the
results. If you are not happy with the new sample, delete it and select the
original sample to repeat the procedure.
Note l: Tlmestretch will require some experimentation. It is not unlike looping
in this respect and you may need several tries at it before you get a
timestretch sample sounding just right. Bear in mind what is going on here in
this process and realize that you can only expect a sample to be stretched or
compressed a certain amount before some degree of irregularity in the samples'
tone becomes apparent.
Note 2: The looping for the stretched/compressed sample will remain the same as
the original samples. As a result, if the original sample was looped, you will
have to edit the new timestretched sample and change its loop length to
something more suitable.
