4C ASSIGNING THE SAMPLE
The SP-12 default assignment places the sampled sound on the lowest available
empty user number, with the sound appearing on output channel 7 or 8. Both of
these can be changed as follows:
1. With the SAMPLE module active, key in 2. The display’s top line will give the
current User number, with a cursor appearing underneath the number. Key in
the desired User Sound number with the keypad (leading zeroes are not
entered); when the display confirms your choice, press ENTER.
If an asterisk appears next to the User Sound number, it already contains a
sampled sound. If you press ENTER, as a safety measure you will be
asked if you want to erase the existing sampled sound.
2. The bottom line will now show the output channel assignment for the selected
User Sound. A cursor will appear under the output channel number. Key in
the desired output channel number with the keypad (leading zeroes are not
entered); when the display confirms your choice, press ENTER. The output
channel number is stored with the User number until changed.
4D SETTING THE SAMPLING THRESHOLD
There are two ways to initiate sampling: Threshold-sensitive sampling and forced
sampling (SAMPLE 9). With threshold- sensitive sampling, once sampling is “armed”
sampling begins whenever the signal to be sampled exceeds the programmable
threshold level. To set the threshold level:
1. With the SAMPLE module active, key in 4. The display shows the regular bar
graph display on the bottom line, and a single bar on the top line that
represents the threshold. If the threshold has not been adjusted since the
memory was last cleared, the threshold defaults to minimum and the display
advises you to “Use Slider #1”; otherwise, upon selecting SAMPLE 14 the
threshold sits at wherever it had been set previously.
2. To change the threshold level, vary Slider #1. Generally, you will set threshold
just above the residual noise of the sound to be sampled (the display’s lower
line will show this noise, if any, as erratically moving bars towards the left of
the line). Therefore, the noise will not initiate sampling, but a signal that
exceeds the threshold will.
Hint: Set the lowest possible threshold. If the beginning of a sound is cut off, the
threshold is too high. If there’s a delay before the beginning of a sound, the threshold
is too low and the sample was probably triggered by some noise prior to the actual
signal.
Note: Once sampling has begun, the SP-12 will continue sampling even if the signal
falls below the threshold level.
