Troubleshooting - E-Mu XL-7 Command Station Owner's Manual

Troubleshooting

A common source of confusion when working with the filter envelope is
that the Attack or Release parameters might not seem to be working
correctly. If you are not getting the expected result, try to analyze the
situation. There will be many times when you will have to stop for a
minute and think, "What am I trying to do and why isn't it working?"
When this happens (and it will), don't panic. Troubleshooting is a normal
part of the synthesis process. Simply examine the various parameters and
try to be as analytical as possible as you solve the problem. The solution is
usually simple. ("The filter is already wide open and can't open any more."
or "Another PatchCord is connecting something to the parameter and
affecting it.") Learning to play any instrument takes a little patience and
practice.
Referring to the diagram below which shows the XL-7 signal flow, notice
that the DCA comes after the Filter. The DCA controls the final volume of
the sound, so if the filter's release is longer than the release for the DCA,
you won't hear it, because the DCA has already shut off the sound.
Instrument
You're getting the general idea by now. Remember not to select a new
preset before saving the current one or all your changes will be lost (the
preset reverts to the last saved version). If you want to save your creation,
select the Save/Copy menu and select a destination preset location for your
masterpiece, then press Enter.
Because you can save your work, it's worth spending time to get the sound
just right. When designing sounds you become an instrument builder as
well as a musician. With XL-7 you can design the custom radical instru-
ments you've always wanted!
