DRUMS
When
triggering
from an acoustic
drum, that is using
a
contact
pick
up
(transducer)
mounted
to the head
or shell,
the same
general
set-up
procedures and parameter
principles
of
triggering
from pads
apply.
However,
due to
extreme
head
vibrations
and
resonance
of
acoustic
drums, keeping the
"factors"
under
control
is
considerably
more difficult.
These tips
should help
you in
eliminating potential
problems.
There are
several
things to consider when purchasing
transducers
(triggers),
and when mounting
them to your
drums.
Output Sensitivity
The difference in
output
levels
between
transducers
is
considerable. While
a really
"hot"
trigger might
work great
on
the snare,
it may not
work as well
on a bass
drum. For
example,
a high
sensitivity trigger
will detect the softer
"grace"
notes
on a
snare drum and
provide the best tracking in
a
tight
pressed
roll.
On
a
bass drum however,
because that same
trigger
is
so
sensitive,
it may
be over-driven
due to the sheer velocity
of each
impact from
the
beater on the
head.
Over-driving
the trigger
can
allow it
to detect every
slight vibration as you hit
the bass
drum.
This
results in
double triggering and
contributes to
cross
talk
problems. It
can also reduce
the
life of the
trigger
itself.
When
considering
trigger output sensitivity towards
applications,
generally
these tips will apply.
1.
Use
"hotter"
triggers for
shell
mounting.
Sensitive
triggers
can detect
signals through
the shell
more accurately
than
others.
2. For direct head mounting
use less
sensitive triggers.
When
possible use a
trigger that
contains
a
built-in
sensitivity
adjustment
There are
several types available.
Mounting
One of the most important
aspects of triggering
is mounting. For
any
trigger to work properly
it must
be correctly mounted
to the
drum.
Always
use
some type
of
a foam
tape,
and
make certain
the trigger is
firmly mounted
with
little
or no movement.
In
addition
to
forming
a
solid
foundation for
the trigger, the foam
tape
also acts
as a
shock
absorber
which helps
to deter double
