4.
Move the cursor to the first field in the bottom line and use the cursor
buttons to advance to the Release pages.
5.
Increase the Release 1 and 2 times. Note the effect as you release the key
on the controller. The Release stages controls the time it takes for the
sound to die away when a note is released.
Working with Filters
The filters make it possible to remove certain components of the sound. A
low pass filter removes the high frequency components or put another way,
it “lets the low frequencies pass.” A high-pass filter removes the low
frequency components from the sound letting only the high frequencies
pass. See “Filter Types” on page 103 for a complete list of B-3’s filters and
their descriptions.
In preparation for the next tutorial, select a user preset and go through and
turn EVERYTHING OFF. Yes everything! Then save it in a User location.
1.
Go to the Instrument screen and select Instrument #009 - 1st4Slow
VibM This is a really rich sound. Since filters work by removing or
accentuating certain frequencies, we want to make sure that we have a
lot of frequencies to start with.
1.
Advance to the Filter Type screen using the Data Entry Control. Select
the VCF Classic filter.
2.
Go to the Filter Frequency and Q screen. Position the cursor in the Freq:
field as shown in the following illustration.
The Frequency parameter determines the filter cutoff frequency or the
frequency the filter uses as the highest frequency allowed to pass.
If you play the keyboard now, you should hear the raw Looped Perc 1
sound. Slowly decrease the filter cutoff frequency value as you play the
keyboard. The sound gets more and more dull as you remove more and
more high frequencies from the sound. At some point, the sound
completely disappears. (You have filtered out everything.) The chart on the
following page illustrates what you just did.
