If you're working on a new track that requires a new sample, you can just use the usual esx method for loading a single sample (you don't have to load in a whole .esx file - which will discard your current info). All the loading/saving info is in the manual starting around page 85. Here's how to load in individual samples:
Loading just a single sample
from SmartMedia
You can load individual samples from a file that was saved
by an ESX-1 or ES-1, as well as loading WAVE or AIFF files.
Loading a WAV or AIFF file
1. Insert the SmartMedia into the SmartMedia slot.
2. Press the GLOBAL key (the key will light).
3. Hold down the SHIFT key and press step key 16
(CARD). (Key 16 will blink.) The parameter dis-
play will show “CardMenu.”
4. Make sure that the value display shows “Load,”
and press key 16. The parameter display will show
“Load.”
5. The value display will show “All.” Turn the dial to
select the file format shown in the value display;
either “WAV” or “AIFF.” Then press key 16.
6. Select the sample that you want to load. The value
display will show “Load,” and the parameter dis-
play will show the “(
sample name
)” for samples that
match the file format you selected in step 6. Turn
the dial to select a sample. At this time you can press
the PLAY/PAUSE key to play the selected sample.
When you have selected a sample, press key 16.
7. Select the load-destination sample number. The pa-
rameter display will show “LoadTo,” ” and the value
display will show “(sample number in the ESX-1’s
internal memory).” (You can press the SHIFT key
to see the name of the sample.) Turn the dial to se-
lect the load-destination number. Already-used
sample numbers have an asterisk “*” at the right
of the sample number. Press key 16 to execute the
Load operation. During loading, the step keys show
the state of progress.
Good luck!
