also affects the level of the feedback signal, so you’ll typically want
to start with I
NPUT
G
AIN
turned down.
Several of the factory programs already have some level of feedback
programmed in, as indicated by the letters “FB” following the name. To hear the
effect of ExtIn Vol and I
NPUT
G
AIN
, call up one of those programs and vary
those parameters.
Audio In
Audio In can also be used to process an external audio source, to get access to
the analog filter as a sound processor. In general, when using a line-level input,
you will want the I
NPUT
G
AIN
control set to minimum. When using a low-level
source, such as an electric guitar, you’ll need to turn up the I
NPUT
G
AIN
to get
sufficient signal level.
When processing external audio, you will first need to turn up the ExtIn Vol
level in the Mixer. Otherwise no signal gets to the filter. Also note that the VCA
needs to be open to hear the input. This can be done a number of ways:
1. Just turn up the VCA Level if you want the signal to go through
continuously
2. Manually trigger the VCA envelope with the P
USH
I
T
button or a MIDI
keyboard
3. Select AudioIn as the mode in the PushItSw parameter, which
automatically gates the VCA envelope with an input signal greater than
a fixed threshold
There are also numerous other ways of opening the VCA using modulation.
Saving a Program
To save a Program, press the W
RITE
switch and the following screen appears:
Write? P:xxx B:x
Hit: Inc if Yes
Press the increment (+) switch to save the current program, or decrement (-) to
cancel (or press the W
RITE
switch again). To store in a different location, use
P
ROGRAM
to select a new destination, and hold the increment or decrement
switch to choose a different bank.
