more than you need, because you can always remove the unused portion

later by using the EDIT A SOUND function. A good length for snare

drums and toms is 1.0 to 1.5 seconds. A good starting length for cymbals

is 1.5 to 3.0 seconds. To learn more about common sampling times for

various drums, load one of the preset sounds disks, then inspect the

various sampling times using the EDIT A SOUND function.

5. Move the cursor to the PRE-RECORD(MSECS) field and select a

pre-record time of 1 millisecond or more. This is the amount of time which

will be recorded before the record threshold is exceeded, preventing the

attack of the sound from being cut off.

6. Move the cursor to the HEAR INPUT field. This selects whether or not

the signal at the sampling input is heard in the stereo outputs. If you are

sampling with a microphone in the same room as the speakers, select NO to

avoid audio feedback. Otherwise, select YES to hear the incoming signal in

the stereo mix.

7. Move the cursor to the FADEOUT(MSECS) field. This sets the amount

of time it will take for the sample to fade down at the end of the sampling

time. This eliminates the need to manually fade down the level at the end of

the sample. Since the fadeout will always end exactly at the end of the

sample, this setting actually sets the position within the sound at which the

decay will begin. This setting may also be adjusted after sampling, both from

this screen and the EDIT A SOUND screen. A good starting value for this

field is 1/2 of the sampling time.

8. Move the cursor to the THRESHOLD field. This sets the audio level

which must be exceeded before sampling starts. The range is 0 to 100% of

the total input signal level. A good setting to start with is 5%. If the input

signal has much background noise, you may need to increase this value.

However, because of the PRE-RECORD feature, a high record threshold

setting will not cause the attack of the sound to be cut off.

9. Connect the audio signal to the REC IN jack on the rear panel. Use a

standard 1/4" phone jack here. However, this is a balanced input, so you

may optionally connect a balanced signal if you have one. To connect a

balanced signal, use a stereo (3 conductor) phone jack wired as follows:

10. Now, let's set the record level. First, set the GAIN switch on the rear

panel. For most applications, use the LO setting. Move the cursor to the

RECORD LEVEL field and set the record level by adjusting the DATA

CONTROL and watching the audio level
